To be with another scientist and make a discovery and share that with a global audience, or working with bear biologists in Alaska, by helicopter - [it's] really what I've given my whole life to. And I get to do that just about every week.

I'm glad I'm inspiring somebody.

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.

We live in a time where we have more extinction happening on our planet than since the dinosaurs were wiped out 50 million years ago.

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.

The challenge is that we live in a time where there's a lot of crap on television.

The natural resources we've depended on, if the places where they exist are not stable, our own livelihood and our health is put at risk.
