A supermajority of animal feed comes from the waste product of crops we that were being grown anyway

According to the Alberta Cattle Feeders Association, 80% of the feed is composed of corn. According to the USDA itself half the corn grown in the US was used for animal feed, and 78% of the world’s soy production is made for animal feed.
Is the waste product of corn and soy included in these numbers?

You’re free to do whatever you want, all I meant is decreasing meat consumption not only will reduce the amount of big animals killed, but also the number of smaller ones. Growing a cow takes a whole lot of grain.

Cows and chickens gotta eat too, and that food is coming from fields as well.
By reducing meat consumption also way less critters will end up dying.
