There is no 'need' for us to eat meat dairy or eggs. Indeed these foods are increasingly linked to various human diseases and animal agriculture is an environmental disaster for the planet.

There's so many issues tied to the meat industry. I mean social environmental humanitarian - all of them. I know that when I'm eating that I'm not hurting the planet I'm not hurting other people on this planet I'm not hurting animals... and I'm not hurting nature.

There are nuclear weapons in China Iran Korea and Pakistan. It wouldn't take much to send a couple of warheads off on this planet somewhere that would cause a lot of environmental damage then if you have got someone who wants to retaliate you have real problems.

I don't think it's too hippie to want to clean up the planet so you don't wind up dying of some kind of cancer when you're 45 years old. It enrages me that these big cancer-research organizations can't be bothered to man the front lines of environmental protest.

I don't see this planet being... they're talking about how they're turning around the environmental problems here but I think it's already too late.

Factory farming is one of the biggest contributors to the most serious environmental problems. The meat industry causes more greenhouse gas emissions than all the cars trucks planes and ships in the world.

I have a private plane. But I fly commercial when I go to environmental conferences.

Unless we keep this planet healthy everything else is for naught.

Our world faces a true planetary emergency. I know the phrase sounds shrill and I know it's a challenge to the moral imagination.

Journey with me to a true commitment to our environment. Journey with me to the serenity of leaving to our children a planet in equilibrium.
