I eat meat, and like many of the others here I don’t need to justify what I eat, however I understand the op’s intentions and so I will tell some of the reasons why I eat meat.
- It’s cheap. I’ll be frank, I’m not trying to spend a bunch of cash on organic stuff that doesn’t even taste good that’ll probably eat through my pockets anyways.
- I’ve been raised on the stuff, of course I’ve had my fair share of mix between vegetables and meat, I could never feel full unless some part of my meal had meat in it. I couldn’t possibly transition to only herbs, beans, nuts and veggies ect. now.
- I don’t see any reason not to, other than yeah processed and hormonized meat. But they use hormones on fruits and vegetables as well. Even if that wasn’t the case, there are just more pros to eating both meat and greens than just being vegan.
If humans never existed to begin with, then the world wouldn’t need humans. But because of hundreds and thousands of years that humans have been alive, the world has adapted so well to them that if they all disappeared now it would probably doom life on earth as we know it.
Edit: But then again, if the world was given the same amount of time, then your absolutey correct that over that course nature would eventually adapt back to humans not existing.
