Over the years, I have seen the power of the oceans to excite, feed, and sustain people. I have also seen them undergo a growing onslaught of attacks, from destructive fishing practices to rising acidification.

Instead of hazarding our future on the dirty fuels of the past, let's invest in clean power that can drive this country forward. Let's cut energy waste, make our economy the world's most efficient, and give our workers a leg up in the global marketplace.

Nearly every president in the past 100 years has declared national monuments, from Teddy Roosevelt creating the Grand Canyon National Monument to George W. Bush preserving 10 islands and 140,000 square miles of ocean waters in the Northwestern Hawaiian Islands.

The U.S. has a proud history of cleaning up our air through technological innovation. We did it with leaded gas, acid rain and countless other pollutants, and we can do it with carbon pollution, too.

I think the kind of landscape that you grew up in, it lives with you. I don't think it's true of people who've grown up in cities so much; you may love a building, but I don't think that you can love it in the way that you love a tree or a river or the colour of the earth; it's a different kind of love.

I see a future where states compete with one another to see which can be the most efficient, and where businesses seek out efficient states in which to locate so they can reap the economic and environmental benefits for their businesses and employees.

We copied laws and regulations from western countries, but enforcement remains weak, and environmental litigation is still quite near impossible.

Truly and clearly, the climate changes.
