Hunting is not what is wiping out animal populations. In fact, for many commonly hunted animals, like deer and many forms of fowl, human hunters are a necessary part of maintaining ecological balance.

Fishing and deforestation are another story.

...and animal farming. It's completely unsustainable as well.

Do be careful with that, whilst I agree that we need to drastically reduce our meat consumption, getting rid of all meat consumption with out some kind of super advancement in other fields will be far worse for the environment. In some place plant based food is more sustainable, in other animal based is.

The Chicken + Talapia conversion to protein is the most efficient animal protein to build.

If only people knew how to cook and flavor foods, then people wouldnt be reliant on beef to make their foods tasty.
