Hope Spots

She wished for protected places in the sea, the way we have national parks on land.

She called them Hope Spots.

Out of that wish came an organization called Mission Blue.

Today, there are more than 160 Hope Spots scattered around the world, each looked after by local people who love their particular patch of water.

Today, Sylvia Earle is 91 years old, and she still dives.

She has spent thousands of hours underwater throughout her life.
