Veganism can not only help with climate change, but also total land use, species extinction, deforestation, ocean eutrophication, antibiotic resistant bacteria, zoonotic diseases and soil erosion. Also, keep in mind that over 90% of worldwide livestock and 99% in the US are factory farmed. And we still needlessly slaughter egg-laying chickens and dairy cows once they’ve been overworked to the point of no longer being profitable enough to keep alive.
