Uncertain what is true, even if it seems somewhat plausible.

But would a pet affect this? Isn’t endangered status about wild animals?

In colloquial language, “chemicals” is fine IMO. It’s clear from context that it’s not H2O. Just like substance abuse is only about drugs, not cornography.

I’m not vegan, but this does not follow from the premise you set out with.

Most animals are slaughtered after around one year. Calf/piglet/lamb is taken away early so the mother can become pregnant. She becomes pregnant through artificial means in most cases, or at the least in an organized fashion.

These ‘gargantuan’ numbers of animals we need to cull would not be more than we slaughter at present, if everyone went vegan. No more mechanical pregnanies, no more offspring, and no need for culling beyond the first thirteen months. Of course, I have never heard a vegan talk about changing all meat eaters overnight, so this is an unlikely scenario, but even if that is your premise, it doesn’t hold up.
