As far as I understand, the imbalance of the two hands is due to the collaborative nature of a species (if I teach you something is easyer if we use the same hand). There are advantages of using the other hand as dominant, in fact in competitive environment like ping pong we see a 50-50 split between left and right hands. This is because the left hand has the advantage of being rare and so the majority is not trained to compete against the minority, while left hand people mostly compete against right handed. If two lefties face each other they are equally disadvantaged, that's why in the end a 50 left 50 right distribution emerges.
My main concern is the acidification of the ocean due to the carbon dioxide equilibrium between the atmosphere and the sea.
There is a threshold level threshold at wich the shell of plankton just dissolves. After that happens I think the whole ocean ecosystem will collapse (maybe no more fishes?)
Also the deep ocean has an inertia of thousands years meaning that we are going to stick with industrial coal revolution levels of co2 in the atmosphere for a lot of time even if we emit nothing.
People wasn't seeing immediate effects because it was hidden in saturating the ocean and now there's no way back in my opinion
This is so useful, I built a Julia server that uses GPU for big computations and I love how simple all of this is, but I still lacked the power of frontend capabilities Julia offers, thank you for tiding it up
I find really helpful writing down by hand the key concepts or phrases I find impactful. Also I draw a lot of pictures to fix the stuff and link it with arrows to show the line of thought
Also fun fact, kangaroos have this same 90-10 split: https://www.nationalgeographic.com/animals/article/150618-ka...
