While cats are little murder machines, the focus on keeping them indoors seems not to ring true to me (in North America). We have systematically killed/displaced all of the natural predators (bobcat, lynx, coyote, foxes, wolves, etc...) how is introducing a predictor to help re-balance things a net loose?
Yes I know what they did in new Zealand but remember there were no indigenous predatory land mammals to replace there

Unlike wild predators or feral cats, domesticated, human-owned cats don't live or die by how much they kill. There's no feedback loop that would prevent them from hunting their prey into extinction. If they over-hunt birds one season and can't catch enough the next, their owners will simply supplement the difference.
It's not even clear to me that birds are a primary food source for domesticated outdoor cats. They might be hunting them just for sport.

Why are you applying human morals to cats?
He's not; cats are notorious for hunting for pleasure. I love cats; I've owned many. They are little killing machines.
How are they?
We might consider it a bad thing to kill for sport, but why is it bad for animals like cats to enjoy hunting and killing other animals? Cats have no such moral restrictions.
No morals were implied or intended. Hunting for sport is unconstrained by population feedback loops.
It’s not about morals. It’s about environmental/ecosystem balance. Parent comment talked about feedback loops and over-hunting.
>It's not even clear to me that birds are a primary food source for domesticated outdoor cats. They might be hunting them just for sport.
This seems like a condemnation of hunting for sport to me.

We must be coming from different places.
I still don't see a condemnation at all. Other than the implication that sport is not constrained by hunger and therefor can have unbounded externalities, which again is not moral, it's a practical observation and concern for bird populations.
Maybe you could pinpoint further which part of the sentence you quoted brings in morality.

It's blame shifting, easier then changing their own consumption behavior, less expensive then spending money on bird feed.
Cats are a smaller problem in New Zealand than is often claimed. The possums and rats are far worse, to the point where NZ is engaging in bio-chemical warfare against them. However the worst thing for birds are not those small mammalian predators humans brought there, but the massive destruction of their livelihood: https://en.wikipedia.org/wiki/Deforestation_in_New_Zealand
Yes, stack rank risks & threats.
Yes, prioritize benefits & ROI.
Yes, cats kill their share of birds.
Yes, keeping cats indoors feels like recycling plastic (pointless).
But I still do it. Because I don't want to be part of the problem.
We make what improvements we can.

Keep your f%@#g cat indoors - or at least in your yard. Cat's don't "deserve" to be outside wandering free and I sure as hell don't need them on my property terrorizing wildlife, tearing up my garden and shitting all over the place.
And no, you're kitty is not a "natural predator" rebalancing anything. It's a pet and as such should be kept under you're control.
Entitled "free roamer" cat owners are the worst - and breaking leash laws in just about every jurisdiction out there. I have zero problems trapping trespassing cats and turning them over to animal control. Not sure why people feel entitled to get a pass on this - it's BS.

Why don’t they deserve to be outside? I disagree with that - I think they do deserve it because it keeps them happier. I find your description of cats (“terrorizing wildlife”, “tearing up my garden”) to be hyperbolic. Domestic cats don’t typically do things like eat through a vegetable garden. As for leash laws - that’s more necessary for dogs because of their potential for aggression and harm to humans. Cats are VERY rarely aggressive, non threatening to almost all humans, and are more likely to run away from humans than say a pit bull.
Your house cat(s) probably don't do much damage.
Something like 2/3rds of domesticated cats are feral.
All told, cats kill > 1 billions birds in North America.
Like this article says, with so many factors and poor data collection, it's hard to quantify everything.
But please do your part. If your cat does go outside, please consider putting a bell on their collar.

Frankly this "they do deserve it because it keeps them happier" reeks of sheer entitlement and disdain for personal property and boundaries. I have had terrible experiences in the past with neighbour cats. And if you don't think cats are aggressive you clearly haven't seen a caterwauling fight mess up the neighbourhood or scratch kids up badly.
Also, many people are allergic to cats. Some of them develop even serious health problems like anaphylaxis. Please restrict your cat strictly to your property.

> 1. Keep your cat indoors.
I don't know. I've been considering pets for several months since I'm now spending so much time at home and, as for many people looking for some at home companionship, it comes down to dog or cat.
I've read a reasonable amount of material that suggests that if your cat is kept indoors it's a lot more likely to be unhappy. So if you must own a cat then keeping it indoors may not be the best strategy for the cat. On the other hand, the point about environmental impact of cats - killing of birds and other small animals - might be a really good argument against having cat full stop. If you can't keep it in a way that ensures its welfare whilst also ensuring that it doesn't cause havoc amongst the local wildlife, maybe don't get one at all.

If you have previously let your cat outdoors on a regular basis, it will likely be unhappy if you stop letting it go outdoors.
Outdoor cats get in fights with other cats, spread disease via their waste, kill birds and wildlife. Neighbors also can mistake your cat for a feral one and call animal control or trap your cat: https://www.humanesociety.org/sites/default/files/docs/carin...

We made it almost a year before our rescue got outside. He was instantly hooked. Would hide for hours under something near door. Bolt the moment it was open.
Seems logical. They are wide roaming predators stuck indoors. If I lived in a box my entire life and then got to go outside just once, my preferences might change dramatically.
We have 3 cats, and only one has any interest in prowling the yard, and we watch her like a hawk, only let her outside with us.
The other two (one born feral, one in a shelter) have zero interest in stalking birds. They're not lazy, just don't care about stalking birds, are more "dog-like" perhaps.
Point is, it's a proper subset of cats wreaking mayhem, and they have very varied personalities, which I offer as another datapoint.

It is absolutely a subset. I've had many cats who go outdoors and only one really paid any attention to birds at all. They seem to be much more interested in rodents like shrews and voles. This is only my personal experience though, but I really would love to see further study on this, since I have bird feeders and a ton of birds in my yard. I'm also curious how it might be different in urban vs suburban and rural situations.

I'm glad that you're taking the time to think through the responsibility that comes with getting a pet, but I think you are coming close to letting the perfect be the enemy of the good here. just keep in mind that there are already more cats than homes willing to take them in (almost a million shelter cats are euthanized each year in the US alone). if we're talking adoption (and we really should be; deliberately breeding cats for sale is part of the problem, imo), you don't need to offer a perfect life for your prospective pet. you just need to offer a life that is worth living at all.

Completely agree here. We have four cats plus foster regularly... the catio definitely created net positive happiness, but the key is really just the elimination of boredom. Cats need stimulation just like people. Some toys, a tower, a good window - just keep on top of their needs and they will be happy

Cat was constantly sneaking out. Cat is much loved throughout neighborhood. Got really good at hunting. To the point a neighbor started shooting at it.
We finally got good at keeping the cat inside. Cat became super depressed.
Got a second cat. second cat peed in every laundry basket and bed in the house in a couple of days. Oh and first cat hated second cat.
Things have calmed down, and cats are happy, and we now have a gate to bedrooms.

My likely unpopular opinion, humans shouldn't have pets any more, i think its an overall net negative driven by peoples selfish need to take care of a thing, be loved and have attention.
Dogs are particularly bad. off leash owners cant control them, we have kill shelters, breeding for obscene prices, dog shit being left all over, dog fighting. Then people just don't know how to take care of them. I had a neighbor that left their dog outside for hours barking. such a nuisance for no reason, and that dog must have been living a miserable life. we keep breeding chihuahuas that no one wants, pitbulls that can't be adopted, and some of these pure breeds like bulldogs are just miserable, other pure breeds have health issues.
Cats we're already talking about.

The main counter argument I usually hear when this is brought up is that many of these animals have been bred for hundreds or thousands of years to be dependent on humans.
To your point about kill shelters, I think the humane society has largely helped fixed this. There was an article on HN this week that claimed shelter killings was reduced from 20% down to 2% based on the efforts of the humane society since the 1970s.
I may be biased as a dog lover, but most of your arguments seem to be based on bad owners. If we can stop bad ownership we should do so but let’s not throw the baby out with the bath water. I don’t think bad parenting existing should be an excuse for abstaining from having children either, unless we regress to a misanthropic world view.

Thanks for this. In college I worked at the Humane Society and helped with the dogs. Very hard work. After working there I realized how most "breeders" are just random blokes with an AKC pure bread who get some dogs together. Some real breeders who monitor trace genetics and try to make the breed better exist, but these dogs usually cost a lot of money, and have specific purposes and customers. Sometimes I wonder if dog ownership should require a license and semi hefty fee (make it more a kin to adoption). But I am not sure...

Yeah most problems do stem from bad owners. But idk how to enforce good dog and cat ownership? At least with kids we have cps even if it isn't perfect and if a crappy kids grows up into a terrible adult we have law enforcement.
But what can you do about terrible owners? Are we going to take dogs away from owners that don't clean up poop or how do you handle communities that don't think their dog needs a leash.

Most municipalities already have laws against this. Hell, where I live there’s a law that can escalate to a 3rd degree felony if your dog looks like it can get out of its fence. What I suspect is an unsatisfying answer for you is that they aren’t enforced because they really aren’t a priority.
That’s unfortunately a part of living in a society. We can’t always agree on what priorities are worth our limited resources. We’ve generally agreed children are a priority and choose to enforce those laws more often. For every person annoyed by bad dog owners, there’s somebody who annoyed by laws not being enforced against noise pollution, poorly parked cars, yard maintenance etc etc. My only suggestion is to get engaged to try and get them enforced if you feel it’s a major problem

We have laws against animal abuse. Some of these laws have strong teeth and can put abusers behind bars for years.
I have two dogs, and they're both incredibly happy. They enrich my life, and I do the same to theirs'. I don't want the state telling me I can't have dogs. That's a kind of liberal fascism that goes against the grain of this country's ethos.
There are dogs suffering in shelters, but there is suffering all around, everywhere you look. Orphan children, homeless people, cancer. If you start passing laws against everything, we'll wind up living in a bubble.
Find negative externalities and tax them if you want a better way of dealing with problems. Don't ban dog ownership.

Let the domesticated variants die out, wolves will continue.
to an extent I kinda agree. I definitely don't think people should deliberately breed animals as pets. but we already have an unnaturally large population of cats and dogs and we have not been entirely successful at preventing them from reproducing on their own. just leaving them be is not an option, as that would devastate the prey population. if the alternative is euthanizing the majority of cats and dogs that currently exist, I don't think we have to feel bad as individuals about keeping a few in our homes.
I highly disagree: humanity has co-evolved with animals and living together with them has always been normal. Reducing it to some "selfish need" is a cynical generalization. Denying pets will not improve the lives of these creatures, it will close their niche and pave the way for the extinction of their species. After millennia of living with them, that would be the ultimate betrayal of our most loyal friends and allies. We can already see that with horses: they are no longer useful and their numbers are dropping fast.
One wild theory is that dogs domesticated us. I could believe that.
Absolutely agree. Especially in the aggregate.
And I still got a dog. Right before some unplanned surgeries. Now, I also totally believe the claimed personal health benefits. Can't stay in bed when the puppy needs to be walked. This dog probably saved my life.
We spend a lot of time at the dog park, so I see the cream of the dog owners. I try to not think too much about all the other dogs who aren't as lucky. I'll just start crying.

Leash training is an option.
And if you are going to have a cat, get 2 so they have companionship.
I have 7 cats now and have had dozens of cats since I was a kid. Cats don't give a fuck about being outside if they've never been there. Now, trying to make an adult outdoor cat into an indoor cat is hellish. But if kept indoors from a young age they are quite happy.
Or they are quite warped.
Did it ever tell you it was happy?
And do you have a substantial body of conversations with other cats to be able to analyse so you can tell when one claiming to be happy is instead stunted and warped and brainwashed into declaring it's love for it's cult leader?

If you have an outdoor cat, you absolutely need to put a bell or something that jingles on it's collar. The sound will alert the birds and give them time to escape.
These have nothing whatsoever to do with cats or insectiside and they're not even remotely "common". The fact that die offs are happening more now, due, as the piece notes, almost certainly to effects of climate change shouldn't lessen the impact it has on people, on the contrary, it should heighten it.
Defaulting to keeping your cat indoors is cruel. Instead put out some bird feeders.
Cats love the outdoors. It's evil to take that away from them. Not all cats even kill birds.

You really don't know what you are talking about mate. Indoor cats live 13-17 years. Outdoor cats average 2-5. What's cruel is willfully exposing your cat to an environment that will very likely result in a reduction of their lifespan by 60-80%. There are plenty of ways to stimulate a cat that don't involve dramatic risk of disease, parasites, disfigurement or death by predator or vehicle.
Pretty sure that you are talking about feral cats rather than cats that are allowed to go outdoors.
I am not. I am talking about domestic cats allowed to roam outdoors unsupervised some of the time.
What’s your source on the life expectancy of outdoor cats? I haven’t observed this having any impact myself. Cats that stay indoors and ones that free roam seem to have the same life expectancy. The ones that roam even seem healthier.
Human Society and University of California-Davis.
Would you happen to have the exact paper?
> Outdoor cats average 2-5.
On the other anecdata, my parents have only had outdoor cats and every single one has made it past 5 - several past 10, one past 20. Of the 10 I can think of just now, only 1 died of "unnatural" causes (car).

The pet cat industry in general is evil. Keeping them indoors is the best way to protect local wildlife, there are still many ways to make an indoor cat happy. If it were up to me, breeding of cats would be banned and existing populations would be the "final" permitted generation.
Or, we have one final generation of people and let nature sort itself out...
I've seen that number before (1 billion birds killed a year) and I'm interested in how accurate it is.
There are appropriately 92 million cats in the US - so that is like 10 birds per cat - I've had a lot of outdoor access cats and most have never brought birds in, or like once or twice a year.
Do cats bring in only a tiny subset of things they catch, or are some cats killing far far more?

On protecting birds, also be sure to keep dogs on a lead when birds are nesting, they can destroy nests in hedges and in the ground, or cause birds to abandon them. https://ww2.rspb.org.uk/birds-and-wildlife/bird-and-wildlife...

> 1. Keep your cat indoors. The low estimate for the number of birds killed in North America pet and feral cats is one billion birds a year.
If your pet cat is spayed/neutered, it should be fine to allow them outside. They will not contribute to the feral cat problem and in fact could help slightly reduce it.

Correct me if I'm wrong, but IME cats don't use their genitals to hunt birds.
It's only fine in terms of preventing them from creating feral cats. It doesn't stop them from murdering wildlife.
Your comment, and the article, makes me wonder what we can do to help misc birds. Concrete actions akin to planting milkweed for monarch butterflies.
Anecdote - I find letting spiders live and using no insecticide results in fewer insects and more diverse and plentiful bird activity.
I wonder if it is possible to set up some sort of supplementary feeding stations. Suet or vegetable oil minced with crickets(or other mass raisable insect grubs??).
They would have to be on poles to stop predators and would have to suit the birds habits, with the ability to feed hovering birds as well as perchers. It will take some research, but lines of these just off roads would provide a number of lines of feeders that could be maintained via the road, with a liftable hopper top I think many birds would adapt to this lifeline during their migration. It would involve many tons of food for the migratory season and to be established in advance.
I wish that were easier. I've found that the cleaning involved is burdensome. It's recommended that you take the feeder down and scrub it with bleach every few weeks to prevent the spread of parasites between the closely packed feeding birds. Worse for me is that even when I can keep the feeder away from the local rodents (a non-trivial challenge), seeds fall to the ground and it becomes a hot spot for insects and rodents. The rodents here are causing major damage to my house and vehicles. It was just higher maintenance than I expected, so I stopped. But I do like having the birds around. Maybe I can start again after retirement.
What kind of rodents do you have in your part of the world that they damage your _vehicles_??
Not uncommon for rodents to chew on hose or wiring.
Just last week a colleague of mine had car electric problems that turned out to be a rat chewing through cables.
It's weirdly common(ish) problem.
It's weirdly common(ish) problem.
They started using soy-based insulation in automotive wiring a couple decades ago.
Sadly, it turns out that rodents really like to eat that kind of insulation. So if you have a car made after ~2000, you need to keep pests away from wherever you store it.

This is also a problem for e.g. excavation equipment that might sit unused for weeks at a time.

The ones living in my pickup's engine compartment are kangaroo rats. The usual repellents don't seem to make much of an impression on them.
Hirundo, I see. So perhaps a non germinating mixture would be good. I agree with the parasite problem. Perhaps 4-6 dunk tanks, so the new full top can be attached and the empty one immersed to soak in the detergent tank(no insecticide) and when you raise the next one, the soaking ones are drained and then a few rinse tanks. That way a crew could have them in the back of a pickup and do the swaps and dunk/rinse changes as they go from feeder tp feeder. This will have to be a short term production line in motion for the 4-6 weeks of the migration. Foods can change as the migratory species change over the various species migration patterns. This needs to be a major continuing state/national effort in many global areas to sustain the birds as the warming and concimmitant changes occur - or we witness the end of many species of birds.
A coworker has an extensive setup for feeding birds, squirrels, and raccoons. He deals with rats and mice with a high powered air gun with a well calibrated scope and sufficient skill that he's able to kill them quickly with one shot. He's killed something like a hundred over the last couple of years.
If you are willing to kill the rats and mice instead of just drive them away somehow, then taking up shooting as an additional hobby might be worth considering.
I've ruled it out because I don't really want to kill them, and also in my feeding area there is no good spot to take a shot from where a miss would not potentially go somewhere I really do not want it to go.

A valid suggestion, but the growing dust bowl might mean that general plant growth is down, less seed and insects = starvation mode. For decades the South west has been depleting all of it's aquifers, so wells are getting deeper and with more salt and other mineral intrusions. This is all tied to the global warming. The great lakes are getting wetter, so major canal works to direct some of the great lakes excess to the southern and western water table is the solution. Now the excess water drains unused into the Atlantic ocean - flooding many US/Canada riverine communities.
What a great oportunity for yet one more economic activity for people. Sad reality is that this economic activity would have no need if not the other econiomic actvities which have caused the problem in the first place.
This starts to look like cutting down the forest and then replantig lesser version of it because it feels not so cozy on plain field...

Not sure why you're being downvoted. Apparently the wild bird feeding industry is worth $2 billion.
Well, we cut down the forests and built farms because we needed food to feed the growing population and economy of the young United States. Now we are seeing over time farms outside of cities being converted to suburbs with little to no habitat for birds. But hopefully over time as the suburbs mature, trees will grow taller and provide more habitat for birds.
Yes, but the ultimate question is how much population is enough and are we capable of self limiting. Oposed to limits imposed from outside. Because with outside limits, it might be to late to keep balance for whole ecosystem, when we hit them (limits)
Are you talking about Human population? Human population is forecasted to peak mid century and begin to decline as more women have access to education and contraception [0]. Many models are predicting this, however personally I'm not 100% sold on the models yet. I think trying to fight the population growth is just as infeasible as trying to move a mountain. I think we have better chances to fight ecological decline by educating the population on effects of overconsumption of goods, pollution, and energy use.

I may have missed a link to a complete list of species tallied in this event, but the photographed birds are mostly Violet-Green Swallows. This species eats flying insects exclusively (source: Birds of the World research database) and would not be able to take advantage of feeders.
Even if we manage to tackle the climate crisis, I wonder how we will address the accompanying ecological collapse that seems to be rapidly accelerating.
We won't.
It makes me sad to think that 50-100 years from now most of the species we know and many more we don't will be extinct.
The only things left alive will be what we need to survive and whatever manages to carve a niche out of the blasted landscapes we leave in our wake.

Isn't this a bit exaggerated?
Better to act like it isn't.
Care to offer your own diagnosis, or just here to frown at people?
I'm old, I tried over my lifetime and failed.
Give it a shot if you care. Education isn't the problem, it's the will to sacrifice our comfort for a better world.
Give it a shot if you care. Education isn't the problem, it's the will to sacrifice our comfort for a better world.
In what sense? Seems realistic to me. The past ten years alone have been terrible for extinction; we lost about 500 species. And there is a feedback loop with these sorts of things.
You're not accounting for adaptation, which nature is very good at.
Not at the timescale humans are forcing.
Things will probably fill in niches later, but there will still be a lot fewer species by the end of the century, which is what the original comment said.
Evolution takes time.
We are much better at consumption than nature is at adaptation.

Do you have a source for that fishy number?
"Since 1900, 543 species of vertebrates have gone extinct. And those are just the ones we know of. In the past century, we have witnessed the disappearance of the ivory-billed woodpecker (Campephilus principalis), the Round Island burrowing boa (Bolyeria multocarinata), the laughing owl (Ninox albifacies), the sea mink (Neovison macrodon), and the golden toad (Incilius periglenes), to name a few."

Here's an estimate that shows one third of all species going extinct by 2070 https://www.cnn.com/2020/02/21/weather/species-extinction-cl... And "In a worst-case scenario, that number could rise to over 55%."
This protected death of millions of species, 50 years out from now, is based on an analysis of 538 of them.
That sounds woefully inadequate information for something as complex as what this model is trying predict.
That's like predicting the weather from only a handful of temperature sensors, or doing patient studies with N=4.

If you select the proper species then you can make fairly accurate deductions due to cascading effects of the food chain.
Key indicators and foundational species like coral are effective metrics.
A mass die offs of coral, which is currently happening, will decimate ocean ecosystems and have a cascading effect on the rest of the world.
People have been saying this for decades, its not new news. Its just inconvenient and impacts shareholders.

Luckily no one is able to predict most anything beyond 4 years in the future. Ask any economist or epidemiologist.
This is false.
We have been accurately modeling climate change for over 50 years now.
Also, epidemiologist have been predicting a coronavirus outbreak specifically for about 10 years, and a larger global pandemic for about 100.
You can choose to ignore science if you want, but that doesn't mean people havent been warning us.

So they have been wrong for about 100 years. Great record.
I predict the sun will run out of steam and we are all gonna die. Furthermore, some volcanos will erupt too.
And we have not been 'accurately predicting the climate for 50 years' : about 50 years ago, there were worries about a new ice age.

I think we can debate magnitude, but not direction.
I feel recently it's been a long time since I came across examples of where nature is increased or restored. Every time it's about nature disappearing.

Bad news is reported far more often than good.
There are signs of the planet greening as a result of higher CO2, for instance.
That doesn't diminish the potential damage, but it's not all bad.

But it doesn't mean it won't happen without a wake-up call. The answer is simple, just stop destroying what has caused unprecedented equilibrium in temperatures during the latest rise of civilization in the past 10k years.

I think it speaks volumes that the very people responsible for this positive change were themselves victims of near extinction due to consumption and greed.
The only real hope the worlds ecosystems have is drastic and sudden reduction in human population, which won't be pleasant for anyone.
This was proved by the resurgence of nature in the areas surrounding Chernobyl. I've been a part of a coral conservation project in SEAsia for the last 15 years, and we have seen more recovery over the last year due to tourists being gone than ever before.
Unfortunately the boat captains who were ferrying snorkelers before have gone back to fishing the reefs, so that change was short lived. We are also beginning to see signs of a major bleaching event.
The long term impacts of COVID are going to see a relaxation of ecological protections worldwide, which I imagine will have a similar effect.

Remember when acid rain was a serious threat, or the hole in the ozone layer? While we still have some work to go, we’ve actually done a lot of good work to stop these problems and begin reversing the damage that we caused. We can and do clean up after ourselves.
It’s not just climate change which is destroying these ecosystems. A huge factor is pesticide killing huge numbers of bugs, which these birds eat.
Please post relevant links and arguments showing that pesticide is killing huge numbers of bugs unnecessarily (we do use pesticides for farming, after all).

climate crisis == ecological collapse they are one in the same
Personally, I envision a world like blade runner 2049. Humans thrive with technology and the earth ceases to be our parent, providing for us.
I don't personally worry about the collapse of the ecosystem as some major long term issue. Major extinction events have occurred in the past, and it portends a massive explosion of diversity as life adapts to the new ecosystem. In a few million years our AI ancestors will tend an amazing garden of native, artificial and synthetic hybrid life.
And if we don't make it... multicellular life will continue to flourish and evolve.

What leads you to believe this? I often see similar sentiments on this website. I don't understand it. Maybe I'm missing something.
High technology is fragile. As far as I can tell, it's nowhere close to self-sufficient. It's the pinnacle of a massive edifice whose foundation is biology: in particular non-human life. Kick that out and the whole thing collapses.
> And if we don't make it... multicellular life will continue to flourish and evolve.
This does seem reasonably likely. Life is resilient. Human life and human engineering, not so much.

Wow. Just wow. That has to be the dumbest comment about climate change and biodiversity collapse I've read so far. If you are not concerned about anything which is not still impacting earth after time-scales that are approaching aeons have passed then you will surely have no qualms about wiring me all your money -- and hell, take some loans before you do that -- because what is it in the grand scheme of things, am I right?

I'm not sure if you grasp the concept of extinction: the permanent removal of species from the ecosystem. Mass extinctions don't "portend a massive explosion of diversity" they literally signal the end of diversity. Ecosystems take millions of years to recover as there are few or no species left that fill prior ecological niches to provide ecosystem services. Biodiversity is not the result of extinction, it's what happens between extinction events as millions upon millions of mutations build up viable species.
It's like cutting down all the trees in the forest and declaring "but in the long run, this will be good for the forest! Think of all the trees that will eventually grow here!"

https://i0.wp.com/mackaycartoons.net/wp-content/uploads/2020...
Can someone more familiar with the field post some applicable models for review?
Systemic change begins with personal transformation.
On a personal level, online calculators tell me I've reduced my footprint about 90 percent. More than the material change, I didn't expect it would improve my life so much -- saving money, time, increasing connection to family and control over my career, plus being invited to communities like food deserts who can benefit most from such transitions. I would bet most Americans could reduce about 70 or 80 percent with simple improvements they wish they did earlier. Most Silicon Valley types maybe 90 percent before any difficult decisions.
My podcast and nonprofit's missions are to help people realize they'll like the change. Everyone presents sustainability as a burden, chore, or sacrifice. In practice, it's the opposite, but no one tries so haven't experienced it. They think not flying means not working or seeing their family.
We're creating systemic change by leading well-known people to change, publicly so listeners have role models. Community influences people more than facts and figures, so we're focusing on people in everyone's communities.
Many opportunities for rewarding change.

My two cents...
Due to this pandemic, I'm finally eating the way I've always intended to. Beans, legumes, brown rices, chilis, stews, novel flours, baking.
I've dropped 30lbs, now close to my ideal weight. I'm also eating non-stop, so it's not due calorie restriction.
To maximize social distancing, and maybe reduce risk of food shortages, I've been buying bulk as much as possible.
Another unexpected benefit is my food waste is now super low.

The good news is that we have the solutions already, we can regenerate ecosystems if we put our mind to it.
For example, regenerate forests using Miyawaki's method: https://en.wikipedia.org/wiki/Akira_Miyawaki#Method_and_cond...
> The Miyawaki method of reconstitution of "indigenous forests by indigenous trees" produces a rich, dense and efficient protective pioneer forest in 20 to 30 years ... this method, if properly applied, quickly produces a multi-layered forest and according to him, a soil with a microbial and acari composition quickly approaching that of a normal primary forest.

Our future Garden Earth will need a lot of labor, investment.
I recently observed a couple dozen volunteers working on restoring some local woods (in a park). Removing rubbish, culling invasive species, restoring top soil, planting saplings, etc.
It was real work. I couldn't believe how small the targeted area was. Less than an acre.
Doing restoration, biomediation at scale would give a lot of people a lot of jobs. At this point in my life, I'd definitely do it for minimum wage and health insurance. My neighbor "retired" a few years ago, now does landscaping. He claims he's never been happier, more fit. He certainly looks it.

There was an article that went by here on HN not long ago that claimed that this is the year that humans and their livestock outweigh all other (wild) biomass. In other words, I think Garden Earth is today, eh?
And yeah, I agree with you that it's going to take a lot of work. Done well, regenerative agriculture is profitable, so that's great.

I think the answer I keep getting at is we change our lives substantially and engage local community to collaborate - gradually, through mutual learning. A number of us talk about this and what we're trying to do at individual/community scales at https://earth-regenerators.mn.co .
Blue Origin, Virgin Galactic, SpaceX is the billionaire solution to fixing the world's impending doom. While the peasants are fighting over the limited supply of clean water, oil, and food, the billionaires of the world are off trying to colonize another planet. Unfortunately, they are likely to repeat the same patterns as Earth and bring that planet to a complete collapse.
Some times I think that humanity is just a disease itself. Despite overwhelming evidence of our detrimental effects to this planet, we continue to plunge all of it's precious resources and while sitting on a pile of ashes. We ponder at the question of "why?"

The OP said nothing about an "accompanying ecological collapse".
Sounds like the bees...
I noticed bees are being eaten by birds. I wonder if this is a result of lack of food or the norm?
Such die-offs are often a result of a "predator-prey" cycle wherein both the predator and prey populations vary inversely over the long term. It is nothing new, nor is it catastrophic unless you're part of the cycle.
Perhaps in this case there were a lot of birds and not enough insects (food). So the birds die off. In a few years, with fewer birds(predators), the insects (prey) will return with a vengeance. In the midst of this new plenty, bird populations will rise dramatically, peak, and then die again. Rinse, repeat...
"Predator-prey cycles":
https://www.khanacademy.org/science/high-school-biology/hs-e...
This article reminds me of the recent years' of German beekeepers writing fretful papers on excessive insect die-offs. Worrywarts have long forecast ecological disaster. But such things have been going on for eons and started long before man was present.

Predator-prey cycles are of course neither new nor catastrophic, but the planetary extinction event we're in the midst of is definitely a catastrophe.
Maybe not yet to the same degree as the oxygenation of the atmosphere, but we're only just getting started.

We are part of the cycle, though. Do not simply assume that our ecocide will not come back to bite us hard.
Mankind already learned that lesson -- and it was a costly one: https://journals.sagepub.com/doi/full/10.1177/03064220188002...

The problem is we've driven these species to the brink, so the "natural cycle" stands an elevated probability of killing them off completely. It's like the way we started out with a million sea otters, killed all but five of them to make fancy hats, and then when a shark eats one of the last remaining females we say oh well what can we do about nature? Luckily in that particular case the species recovered somewhat, but there are lots of examples of animals that we've reduced to a handful of individuals that now face extinction due to "natural cycles".
So, I had a similar thought to yours, which was that it is not unusual for populations of any animal in the wild to have long term cycles. The idea that this is necessarily not a big issue, though, does not necessarily follow.
For example, some (not all) scientists think we have seen a large-scale decline in insect populations due to insecticides being used in ever-larger quantities in North America. If insectivorous bird species are dying of malnutrition, this could be a result of human insecticide (over)use.

It's not just North America.
The fact that well fed, cleanly kept, domesticated bees have been dying in enormous numbers points to something more than the eb and flow of nature.
As for the birds, you have to ask the same question: what makes you sure it's just Predator-prey?

I didn't say that it was "just Predator-prey". But birds are definitely both, and exist in a web of predator-prey relationships.
Therefore it is contingent upon the presenter to provide at least some evidence that this is a "runaway" situation - a "die-off" rather than the usual alternatives, which happen all the time as Exmoor states in his initial post on this thread.
Instead we're shown a bunch of dead birds. That is followed by a chorus of webshits here providing subsequent "the sky is falling" lamentations, moaning and gnashing of teeth.

I live in New Mexico. I found 3 or 4 dead songbirds outside my house this fall. This was happening in ~October. The die-off has halted since then, I'd estimate it lasted about 3 weeks.
On a slightly unrelated note, Turkey has put money into feeding stray birds and pigeons and the like, while the lockdown happens (Turkey randomly became #4 per after US, india, brazil out of nowhere in starting in December, all of them have higher populations, sometimes MUCH higher [1]).

The local gov decided to pay to keep them fed instead of having a bunch of half-dead animals walking around on the ground when they get out I guess. Or harassing homes most likely.

The slow progression toward consensus conclusion that pets are wrong and no one should have one is depressing.
I think it's wrong to even think about the fact that cats kill birds. That's between the cats and the birds, and even the fact that some humans own or feed some of those cats is irrelevant.
Not only that, did everyone forget all the humans that have birdfeeders and the even more that simply litter and leave edible garbage everywhere? (or in garbage bins for that matter)
Most of the problems brought up about either dogs or cats sound to me like the most sane and correct reaction which does the most good for everyone, is to simply be more tolerant of other people's pets as a fact of life, the same way we have to for their babies.
It's like the annoyance of a baby crying in some place like a restaurant or a plane. I agree, that is super annoying, if you've somehow managed to live too much of your life shielded from that annoyance. But really the problem is not the baby or the fact that a parent took the baby into a public shared space, it's that you are too much of a baby to tolerate it.
Intolerant selfish douchebags can sort of get away with making the argument that you don't need to go out to a restaurant with a baby, and can actually turn their intolerance into someone els's inconsideration. You could choose to stay home where I don't have to deal with your unsightly family, or just don't have any kids like I didn't, or just leave them with a babysitter etc etc.
But what about a plane? If you have a kid you simply can't travel?
But even the restaurant example has that same essense of unreasonable discrimination as the plane example.
I say people are forgetting that life and being a human is a bit messy and inconvenient once in a while, and it's fundamentally wrong to go quite so far towards trying to erase all the mild blemishes on your perfect clean unruffled existense when that requires telling other people they can't exist eny other ways except exactly the same sterile predicatble compartmented existence you like.
Not only do I say dogs and cats should be more tolerated as simply a recognized reasonable ingredient in life, and that it's not reasonable to expect to erase all trace of their messiness any more than it is to do so with human babies, I say it's also depressing that the universe of animal companions has been reduced to cats and dogs. How neat and tidy and boxed a web form with a cat or dog radio button.
For all the obvious obvious arguments, it's still just fundamentally not a good progression.
This all comes from someone who has neither pets nor kids. I am not arguing from the bias of having a kid or a pet myself that I want to be free to annoy everyone else with.

Weather-related events are pretty tough to predict and prevent. There are several things you can do that will have a direct effect on bird populations. I'm short on time, so I'll just list the two most impactful ones:
1. Keep your cat indoors. The low estimate for the number of birds killed in North America pet and feral cats is one billion birds a year. That doesn't include the many small mammal, reptile, and amphibian species which are the base of the food chain for larger species of birds.
2. Reduce your use of insecticides both directly and via store-bought foods. There's a lot of evidence that insect populations are experiencing a population collapse, likely due mostly to accumulated insecticides in the ecosystem.
