Being evil is something that only humans are capable of.

Be assured that our individual actions, collectively, make a huge difference.

A book came out recently written by scientists and environmentalists that made me so angry. It said the only thing we have to worry about is big industry. Each individual who tries to make his or her own environment better is useless. I find this criminal, because then you have a billion people all saying, It doesn't matter what I do because I'm just one person. But if you turn that around and a billion people say, What I do does make a difference, then it will make a difference.

My mission is to create a world where we can live in harmony with nature. And can I do that alone? No. So there is a whole army of youth that can do it. So I suppose my mission is to reach as many of those young people as I can through my own efforts.

When you borrow you plan to pay back. We're stealing from our children - so many people have no intention of paying back.

It's easy to become hopeless. So people must have hope: the human brain, the resilience of nature, the energy of young people and the sort of inspiration that you see from so many hundreds of people who tackle tasks that are impossible and never give up and succeed.

One individual cannot possible make a difference, alone. It is individual efforts, collectively, that makes a noticeable difference - all the difference in the world!
