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

Humans are the only creatures with the ability to dive deep in the sea, fly high in the sky, send instant messages around the globe, reflect on the past, assess the present and imagine the future.

I am driven by what I know; that the world I love is in trouble.

It is not too late to turn things around.

Since I began exploring the ocean in the 1950s, 90 percent of the big fish have been stripped away. Tuna, sharks, swordfish, cod, halibut, you name it, the numbers have just collapsed. Also, about half of the coral reefs are gone, globally, from where they were just a few decades ago.

You should ask where your food is coming from.

When I arrived on the planet, there were only two billion. Wildlife was more abundant, we were less so; now the situation is reversed.
