Our health as a society, our robustness as a community, as a nation, as a people, is not only dependent upon fiscal stability, military might, political strength - it's also dependent on a healthy planet.

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.

I think the hardest part about my job is the best part of my job - the travel.

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.

We are not far away from the point of no return when it comes to life on earth, and we have some radical choices to make.

I am really sobered by what's happening to ecosystems around our planet and to the wildlife that is to be found there.

When you're in the middle of nowhere, when you're on this tiny little island, probably one of ten people ever to step foot on this island, it's taken you a week to get there by boat - and you step near to an albatross nest. It doesn't even look at you as the enemy. You get this great nature moment. Until you realize the albatross, along with the thousands of other winged albatrosses next to it, has constructed its nest of trash.
