The seas need their own Kyoto Protocol.

The Ocean Health Index is like the thermometer of the ocean. It will allow us to take the temperature to know what is going on at the global level, trying to integrate different impacts, including overfishing, invasive species, coastal development, and climate change.

When I was six, all I dreamt about was becoming a diver on Jacques Cousteau's boat, the famous Calypso.

What we have now - a world without [marine] reserves - is like a debit account where we withdraw all the time and we never make any deposit. Reserves are like savings accounts.

What better way to learn about life in the ocean--and how we are changing it--than through stories of blind zombie worms, immortal jellyfish, and unicorns of the sea? The Extreme Life of the Sea is an insightful book that inspires awe and wonder about our ocean, and brilliantly shows us the immense possibilities of life on Earth.
