That may be, but by becoming a vegan, you don't make a problem any better, you just neglect to make it worse. And since I have a very limited ability to make this issue worse and no power at all to make it better, the only ethical reason not to eat meat is to protect my conscience.
Besides, extra production when it comes to meat means raising another animal when previously one would not be allowed to mature. Its life may be short and unhappy, but I value a life of suffering more than no life at all.
So you are nearing the end of your life due to some disease, and the doctor tells you: "At the moment when you would otherwise die, we have a procedure that can give you an extra two minutes of life. Unfortunately, you will spend all of those two minutes in utter agony, as if your entire skin were flayed and bathed in salt and red-hot barbs had been simultaneously thrust into your throat, genitals and anus. Then, after two minutes of this, you will die." Will you opt for the procedure?
Just a thought I had the other day; what do you think that the political ideas of conservatism have to do with cognitive bias? I mean, how much are people willing to change naturally, without arguing any points?
I know very little about all of these things, so forgive me if this is a silly thought.
