There would be very little point in my exhausting myself and other conservationists themselves in trying to protect animals and habitats if we weren't at the same time raising young people to be better stewards.

You may not believe in evolution, and that is all right. How we humans came to be the way we are is far less important than how we should act now to get out of the mess we have made for ourselves.

My mission is to create a world where we can live in harmony with nature.

It's not Africa that is destroying the African rainforest, it's selling concessions to timber companies that are not African, they are from the developed world - Japan, America, Germany, Britain.

We're the ones who can make a difference. If we lead lives where we consciously leave the lightest possible ecological footprints, if we buy the things that are ethical for us to buy and don't buy the things that are not, we can change the world overnight.

there have been too many events in my life, and in the lives of my friends, which have defied any kind of scientific explanation. Science does not have appropriate tools for the dissection of the spirit.

I've always felt you don't have to be completely detached, emotionally uninvolved to make precise observations. There's nothing wrong with feeling great empathy for your subjects.
