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.

Whether it's exploring the woods around where I grew up, or even today exploring the coastal habitats and environments where I live in New England, or in a remote wilderness we're featuring in one of my series - I love to be in the field and I love to explore.

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

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.

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

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.
