Underworld

Did not know much about the deep oceans before listening to this book. I was very impressed with the history behind deep sea diving, the technology involved, and current aspirations. It was very inspiring. I hope that no one ever mines the oceans. As a nonfiction, it was very well written and I ended up watching Aliens from the Deep and other documentaries that confirmed the info within this book. Renews a sense of adventure and reminds us where we are in the world with our environment. Highly recommended. Everyone should be informed of the ocean and protect it whenever possible. Wish I could deep sea dive!!
