Highways crisscross the land, simultaneously forming pathways and barriers. - Sylvia A. Earle

The next time you dine on sushi -- or sashimi, or swordfish steak, or shrimp cocktail, whatever wildlife you happen to enjoy from the ocean -- think of the real cost. For every pound that goes to market, more than 10 pounds, even 100 pounds, may be thrown away as bycatch. This is the consequence of not knowing that there are limits to what we can take out of the sea.

I think one of the most important trends is the awareness and willingness to embrace places and to recognize that protecting nature, the natural systems, have benefits back to us in terms not just of better health, not just because they're beautiful - it's not even a choice anymore; it's necessary for our existence. We have to realize we're a part of nature. We can see the connection between trees and climate. We can see connection between the forests and the ocean, the phytoplankton capturing carbon, generating oxygen, maintaining a planet that works in our favor. This is common sense.

We have an opportunity, now, to achieve for humankind a prosperous, enduring future. If we fail, through inability to resolve thorny issues, or by default born of indifference, greed, or lack of knowledge, our kind might well be a passing short-term phenomenon, a mere three or four million-year blip in the ancient and ongoing saga of life on Earth.
