Oh boy, why are you arguing about things that you clearly don't understand? "Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose." Veganism doesn't care about climate. People don't go vegan to save climate. Some adopt a plant-based diet though, but these are separate bubbles that just barely intersect.
