As i said in another comment, the way we treat animals is and should be different from they way we interact with other humans.

I dont advocate for the rule of the mightiest between humans. For animals, i think we dont have any moral obligation in the way we treat them. Doesnt mean im ok obliterated species or kill rare animal for sport, just that we are ok to eat them.

considerably worse for your health

Not quite the case. The way we in the western world consume meat is not particularly healthy. But a vegan diet is not healthier per se. You can have a pretty healthy diet that includes meat (although definitely with less meat than the average person in the western world consumes) and you can have a pretty healthy vegan diet. The difficulty with vegan diets is that humans are biologically omnivores, and while it is possible to lead a healthy vegan diet, one does have to be much more careful about their diet so that one doesn't miss any important nutrients. There's a reason the human palate is trained to like meat.

to the environment

This is more an argument to reduce meat consumption than to eliminate it, something I am entirely for. Whatever food we consume, it will just about always have an impact on the environment. The question is how we can reduce that impact to a point where it is sustainable.

The interaction between human and human and animal and human are different.

Theres not much elso to say. What is true for how we treat animals, the fact we can eat them (in my opinion) because we are over them, doesnt reflect in how i think a human should and can treat another human. Thats it
