Maybe I'm missing something, but I don't see how we'll ever run out of arable land. The Earth has been warmer than now, in the distant past: there were times when the poles were not frozen over. Of course, this means the sea level was higher than now, so melting all the glaciers means a lot of our cities (and probably most of Florida) will be underwater, and it isn't so easy to pick up a city and move it to higher ground. A warmer Earth probably means more deserts, but there should still be arable land, in places that are currently cold tundra perhaps.
- parineum 3y agoThe end-end-end game is Venus-like conditions on Earth. I find that pretty unlikely though considering that population would be so reduced significantly much before that and industry would be effectively stopped. As long as any biology survives, they'd likely eventually be able to reverse the changes.
- midoridensha 3y agoI don't see how. As I said before, the Earth has been hotter than it is now. We're currently in an ice age, and coming out of it: that's why we have ice on the poles. The Earth was never like Venus, and never will be; the thing that humans are doing now is burning a bunch of carbon that was stored in prehistoric times. Back then, it was all in plants in the biosphere, when the Earth was warmer than now.
- cassepipe 3y agoYes, it was warmer... and there were no humans either.
