I am really inspired when I am in an experience, at the front lines of conservation, and I see someone - a woman, a man, a child, a person - who has given up an opportunity to have a family, an opportunity for financial riches, even an opportunity for security, [to] put their whole life on the line to protect a species.

We know that when push comes to shove, [we can] drive ourselves to save our planet.

Running is my addiction. It's always present. I'm constantly thinking about my next run.

I'm glad I'm inspiring somebody.

I think a human animal is far more wild and unpredictable and dangerous and destructive than any other animal.

Many of the medicines we use today, to fight everything from AIDS to cancer, originate as a toxin in an amphibian skin. When we lose these animals, we lose resources. We lose keystone species in the environments where they live.

Many scientists would argue that we are now in what is called Extinction, and it's caused by this perfect extinction storm: climate change, habitat loss, pollution, unsustainable exploitation of species and habitat resources, and of course, human population explosion. All of these factors work together and conspire to drive a species to extinction on our planet, every half an hour.
