Ignorance is the biggest problem of all for the ocean - and for many other things as well.

There's plenty of water in the universe without life, but nowhere is there life without water.

We don't have to be that greedy generation that just continued to take down the underpinnings of what makes the planet work in our favor.

The Earth is a unique system in the universe, the only planet we know of that's hospitable for humankind.

There are now more than 4,000 places in the sea around the world that have some kind of protection. The bad news: You have to look hard to find them. What you find instead is destructive fishing, mining, gas and oil exploration.

When I was 12, we moved from New Jersey to Florida. The Gulf of Mexico was literally my backyard. Every day, I could see the ocean. At low tide I went out and played in seagrass meadows that used to come right up to the shore, filled with tiny seahorses, pipefish and soft corals. There was so much life! But then I witnessed the change, the loss of the shoreline, the loss of the mangrove trees, the loss of the seagrass meadows. Shallow bay areas were turned into parking lots.

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