I deeply admire Sylvia Earle. She is one of my heroes and has done more for ocean conservation that possibly anyone on earth. Her career exploring & studying the oceans, and work to create ever expanding areas of protected ocean inspires me as a scuba diver, an ocean lover, an environmentalist, and a woman.
Sylvia Earle is one of my sheroes -- she's a marine biologist, aquanaut, spent like a month living UNDERWATER in an ocean lab in the Gulf of Mexico, and created "Hope Spots" which are like rainforests for the ocean. She's amazing, this book is beautiful and wonderful.
