By the end of the 20th century, up to 90 percent of the sharks, tuna, swordfish, marlins, groupers, turtles, whales, and many other large creatures that prospered in the Gulf for millions of years had been depleted by overfishing.

You don't have to touch the ocean for the ocean to touch you

We have been far too aggressive about extracting ocean wildlife, not appreciating that there are limits and even points of no return.

With care and protection, with safe havens in the ocean, there is still a good chance that we can turn things around.

The image of Earth from space transformed our view of ourselves. It is maybe the most important image that exists - because we can see ourselves in context in a way that otherwise would be really hard to explain. It should inspire us to wonder about it, to want to know everything we can about it and do everything we can to take care of it.

With every drop of water you drink, every breath you take, you're connected to the sea. No matter where on Earth you live.
