OMG. I have one of the original SGI 24” 1080p flat screen CRTs (went with the onyx2) in storage. One wonders what that’s worth :) fundamentally a better tube ..
If you repeatedly harvest crops from soil without working on building it, this is what happens. Each crop progressively removes some nutrients from the soil with the result that the soil nutrients, and nutrients in the derived food gradually decay. Most petroleum/chemically derived fertilizers do not replace such. It is a known phenomena organic farming circles. Organizations like Rodale institute are working to correct this my improving soil health - but in general we’re been on a long program of “withdrawing money from the bank account without paying in”.
It's beyond dumb and currently all stick and no carrot. By that I mean - at least in CA - a huge state bureaucracy including visual inspections that essentially precludes any real modifications to vehicles - unless you see a referee in which case it is a crapshoot on approval. We would IMO be better served by larger tax incentives on electric, and reduce the CARB bureaucracy enormously - insist on a simple tailpipe test "as it blows". Ridiculous standards have effectively forced small, high compression, often turbo charged, engines on consumers which run extremely hot (observe the heat shielding on newer subarus intended to prevent the engine mounts from burning out). Such engines, while fuel efficient, will never last the 300k miles we saw previously, without extensive messing with - by that I mean engine pulling, gasket full gasket and ring replacement type operations. If you want longevity, the older style toyota, lower compression, engines - which run cool and are marginally less fuel efficient (available in most other places in the world) will last in the 1m mile range.
Came here to say this. If you had a super long, very sensitive, trunk with a huge bee attracting hole at one end that bees could fly into and then sting inside, you'd be scared of them too .....
What you are referring to is a "screened bottom board" in langstroth (modern box) hive beekeeping terminology. Mites fall out of it when bees groom (if kept clean) and cannot return as they can only climb a certain distance (6" is what is generally held as being this distance). However, modern hives have other issues which may be more or less prevalent in different locations and some have argued they were primarily designed for honey production, not honeybee health. In my location, which gets quite cold in winter, the thin walls of langstroth hives have undesirable properties - being too thin to provide insulation, they get cold and then transpiration from the bees condenses as moisture on the inside of the hive, leading to mold. Other people see other problems - no hive design is perfect in all locations - many different location specific designs existed in antiquity, from the clay tubes of the Egyptians to the skeps of the English beekeeping and everything in between. I do note that in the wild, honeybees select a wide range of places in which to live, but seem (to many) to prefer hollow trees. Organization like boomtree bees and gaiabees encourage this preference by providing log type hives and report good results as well as evolved resistance to the varroa destructor, the parasitic mite to which you refer.
