it has definitely reduced the current overall meat consumption in comparison to the scenario of this person having continued to eat meat.

this can't be proven. what makes you think more meat could possibly have been produced?

• lots of people avoid meat.
• meat production continues to increase every year.
• the problem isn't with eating

Literally word for word what you said. Basic math disproves this. 100 people in the world, 10 are vegetarian, meat industry needs to feed 90 meat eaters. Each person has 2 kids, all children of vegetarians are magically vegetarians. Now there are 300 people. Let's say 50 of those meat eaters go vegetarian (way more percentage wise than in reality) The meat industry has to provide food for 220 meat eaters. Meat industry get bigger.

This is a strawman

You have no idea what that means, apparently. Something you don't like hearing doesn't make it a straw man.

There are a thousand problems with the meat industry, most of the world could and should be vegetarian. I am one. Throwing one liners around that is blatantly incorrect doesn't help the cause. It actively hurts it when people see through the bullshit and think then the idea behind it is bad.
