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'm a biologist. At my core, I'm a naturalist.

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.

The number one issue that Ocean Mysteries has opened my eyes to is, no matter where you are, whether you're on a beach in Hawaii, you're diving in the Pacific, you're in a remote archipelago, or you're in the middle of nowhere - I am blown away and sobered and crushed, emotionally crushed, by the amount of marine debris, of garbage, that is now in our ocean.

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

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.

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