Pool starts with "all roads lead to population reduction." And yet it's the Left who want to warning label everything and feed people in overpopulated countries.

They must meddle and "save" everything from tree frogs to humans.

Back in the day people who lived in drought stricken and other inhospitable areas knew how to migrate and find somewhere better. If they didn't, they got Darwined out of existence. Now liberals drop gruel on them so they can pop out more humans the land can't sustain.
If the global overlords are trying to reduce the population, it's pretty easy to do that: leave people alone and they'll reduce themselves.
