The consumption of animal products isn't the problem.
It is the exploitation of the production for profits, which is not a choice of the consumer. This is what causes the problems in nature: increases in greenhouse gasses like methane and the inability of our planet to re-uptake carbon through the reckless destruction of carbon locking plant life environments like oceans and forests, etc all.
You can point fingers at people who want to eat meat all you want but personal responsibility is incapable of balancing out the atrocities that are rewarded thru capitalism. This is intentional, and it is being perpetuated by the ones being rewarded for it. The rich.
If you think for one minute that not eating animal products is going to resolve these issues, then you're deluding yourself.
There is nothing wrong with not eating animal products, if you can afford to live like that. But be honest with yourself about the realities that others experience; both those who can't afford to or just don't want to live like that, and the ones exploiting the world's resources for personal gain. There is a huge difference in culpability between these groups.
