We need protein to feed the world. Beef and lamb are environmentally horrific, and for some people there are ethical problems too. Chicken is less harmful for the environment (still pretty bad), but the ethical problems for most forms of chicken (anything other than properly free range) are severe.

We could try plant based diets for everyone, and if done correctly that would increase health, but it's possibly tricky to do.

Supplementing a plant based diet with entomophagy could feed the world at considerably lower carbon footprint than current meat based diets.
