Don’t have children

A+ my friend. Solve this one, and you solve most of the others.

However, eating animals isn’t inherently bad on its own. It’s the SCALE at which we do it. Animals have been eating animals since there were animals, and as long as there is a natural balance, this can be a good thing. Factory-farming for billions of humans is where it all falls apart (much earlier than that, actually)

You either care about the future of humanity and their place on Earth, or you don’t.

I couldn’t give less of a fuck of humans make it or not, but the Earth and its other inhabitants don’t need to go down with the shitty ship humans built.

I agree with your overall point, though, but I think the main solution to the problem is simply to use a condom. Most of the rest will sort itself out or be much easier to solve after there are less of us.
