Most problems would simply not be a problem if we drastically reduce the human population. Which would not only avoid the issues caused by climate change but also would prevent further increases in pollution and CO2 emissions.
I don't know why the best solution is often the less talked about. Just stop having so many children. We don't have 70% infant mortality rate like we used to, there's no need to have 4 kids to preserve your legacy.
One difficulty with that is that the way we organize economies currently depends on having a working-age population that is large enough to support the non-working population. When you have far fewer workers than retired people you start having problems. I don't know what the answer to that is, but it's another instance of how any plan to seriously address climate change tends to require deep changes to how we run society. The current systems can't simply be tweaked to make the problem go away.
We already have far more people than necessary jobs. One person with modern trchnology can produce way, way more than one person could even just a century ago.

This is only a problem if production does not increase dramatically, as it has for the last century. The reason it feels like there are insufficient working people is because parasites siphon from the resource distribution between more and more productive workers and their non working counterparts
Yeah. Thanos should simply have made half of all living beings gay.
Much less violent and this would probably also make future generations more likely to be gay too.
So it‘ll probably have a much more longlasting effect than killing 50% once.
