Here’s an argument to think about.
If you and your friends stopped eating meat there would be lots of animals that will not exist and that would have existed had you and your friends continued to eat meat. This is true because the meat industry produces animals (indirectly) in line with demand.
But as bad as conditions are for factory farm animals, it is still better for those animals to have existed than to never exist. Even though their lives would be even better were they to live on a peaceful farm, the lives of factory farm animals still contain on balance more pleasure than pain, or for whatever other reason it is a good for them that they exist.
So, if you and your friends stopped eating meat you would be harming these potentially existing animals by preventing their existence in a way, and that’s not a good thing to do. So, for the sake of the animals you and your friends should keep eating meat.
