I am as health and environmentally conscious now as I ever was, only aware that vegetarian & vegan diets in America are atrociously unhealthy. Offering cheap, low quality, fake food is not a technological advancement.
And I am not sure meat consumption is the problem.
Factory farming and industrialized agriculture are the big issues: the greed of the majority of the food supply causes death, destruction, and misery on beings regardless if you are eating kale or cow.
Eat pasture-raised & local if you care about the environment and your own health...
