For starters, as a biological species we value our kin above all else.
So first our family (our closely related genes), then our species. It is super natural. You don't really see true altruism anywhere in nature. It is extremely rare, at least.
Ethical is relative, and purely subjective. Biologically, you want your species to thrive. Without preying on other animals, we would not be where we are, in terms of civilisation. We are at the top of the food chain, and if you look down the scale, you will always see a being taking advantage of others, until you reach the photo-synthesisers, those who produce energy out of inorganic materials.
I can never look at humans and think we are above all else: we are still an animal species. Death is something common in nature. Every living thing will suffer (if they can) and die.
It is also hypocritical to say "I don't eat animals", but live and capitalise on a system that, to exist, destroys and kills in mass. For you to have access to your phone, many animals died. Entire pieces of land were destroyed.
My two cents anyway. But I am in no way against veganism, as hopefully you will know, and I fully support the principle and movement, as long as it is coherent.
