> When you have an environment stressed by too many people, (which is, in fact, a thing)

No. This is untrue. Not only is it not true, it is a billion miles from being true.

It is true that current consumption habits are grossly unsustainable. But it's the consumption habits that are the problem, not people's desire to exist. We are absolutely capable of ensuring the prosperity of all people on Earth and many many many many more while being fully sustainable.

For real though. No one with relevant expertise disagrees with those statements. The idea that we just can't support everyone is capitalist garbage. It blames those with the least capital and offers them up as sacrifice so that we all get our own cars.

>People are starving for fucks sake.

Not because we can't make enough food. Because we can't extract sufficient wealth from them to justify giving them food. There is more than enough food in the world to feed everyone. It is fundamentally not an issue of production. It's an issue of economic exploitation.

>’m talking about family planning and birth control.

You're taking about removing people's right to control their own reproduction. That's powerfully wrong. It's also completely unnecessary and won't in any way achieve the goal you want, but regardless it's very, very wrong. It's just fundamentally untrue that we have an overpopulation problem, and pretty much every qualified expert agrees that there will never come a time when overpopulation becomes an issue.
