If you’d prefer not to be born yourself, do not have kids. Hell, just go kill yourself right away and you will save the environment and the planet more than if you go around spitting stuff against the most natural and beautiful thing ever - having kids.

If you are happy to be alive, at least majority of the time, have kids, as normal people do. It is good for you, it is good for the kids, it is good for the planet, it is good for the universe.
