I've been vegan for 15 years, and it turns out it makes a very big impact on the environment to eat fewer animal products, which cause more greenhouse gases than all of transportation combined.

I was a hostess in a restaurant in New York when I was 21, and I was too good of an employee. I was putting most of my energy into that instead of acting. But my father told my sister and me to look at whatever needed to be done and do that job well, no matter what it was.

I think its important to speak up for the environment because the Earth is not saying something.

The real challenge for a vegan is getting vitamin B and omega-3s, but you can get those in a vegetarian supplement.
