Now I've said I have 3 reasons to be vegan: Ethical, Spiritual, health and Environmental. I actually list environmental last, but these two movies really make the case that if you really love the environment and yourself, then you should be a vegan.
Kip Anderson dramatizes how eating meat leads to the most pollution and destruction of the environment, more than transportation by far, more than anything by far. All the envirnmental organizations don't mention that because their bread is buttered by big business that is invested in carnism. Then he demonstrates that health organizations don't mention how deadly meat is, even though they claim to be to help diabetes or cancers...
I think first about the ethical precept to not lie. They lie like tobacco companies did. They suggest you eat meat, which helps you to get diabetes, cancer, high blood pressure, heart disease. The best way to cure these things is to eat a vegan diet. There's really no logical reason to eat meat. Or consume meat products, which health wise are just as bad. That is what changed me from vegetarian to vegan. The health factor is so much better for the vegan diet.
My doctor always tells me her macrobiotic friend still got cancer. So what? It's not a one to one correspondence, but it is a factor. But it gives you so much more energy to eat vegan.
Go watch these two movies and talk to me.
My friend thought What The Health over stated their point, which undermines the point, by having a woman who needed hip replacement to be walking around. She still needs hip replacement. But her energy level and whatnot still improved greatly.
People focus on transpiration or whatnot. That's nothing compared to being vegan. The meat industry, the dairy industry is creating all the environmental problems. Go watch these two documentaries. They have a similar format and form, same director.
