I always find it strange that the most immediate and effective change any individual can make is giving up or greatly reducing their animal product intake. Will it fix the world? No. But would it actually at least somewhat of a difference? Yes. Is it something you can do right now, today, without any real effort whatsoever? Yep.
But what is pretty much no one willing to do? Give up/reduce animal products in their lives.
It was the easiest change I ever made. 31 years ago. No meat. No dairy. No eggs.
Oh, and no car.
Guess that’s too hard for people and they’d rather die in a war over water.
