Evolution is not something to be feared. It's to be celebrated, embraced, and understood.

The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning.

Humans have always wondered the big questions, "Who am I? Where have I come from? Where am I going?" It's part of human nature. It's perhaps the underpinnings of religion.

I want everybody to go jump in the ocean to see for themselves how beautiful it is, how important it is to get acquainted with fish swimming in the ocean, rather than just swimming with lemon slices and butter.

The end of commercial fishing is predicted long before the middle of the 21st century.

If I seem like a radical it's because I have seen things that others have not.
