nutritional value availability it being delicious tradition and heritage sustainability
and so many more
Even you whole food vegan types have a final form as a hunter.
It is the logical conclusion if you care about the environment and animals, want low CO2 emissions and stay away from high intensity farming.
taste, tradition and heritage are not justifications. You can justify cannibalism using the same arguments.
Canibalism can cause severe deseases, if the protein isn't prepared correctly, but for craps it seems the way to go to find stability with any habitat.
It is my personal opinion to strive for a future with more variety in food and more opportunities.
Instead of being vegan and eat a block of starch each day.
