it’s absolutely horrific for the ecosystem as insects are destroyed en masse to serve the needs of the industry.

Don’t livestock consume just as much, if not more, plant matter to support the meat industry as humans would? Sort of a diminish caloric returns, since those calories have to support the life of the meat-creature which then has to support the life of the omnivore?

I would think that vegan diets would be a net-benefit in terms of pesticide and fertilizer use, and that plant-based diets would be more sustainable.

But I’m uneducated in this and haven’t done sufficient research.
