Though often hidden from view under the sea, kelp forests are one of the most important and dynamic marine habitats, supporting numerous species of marine life.

But kelp forests are also under threat from pollution, overfishing, and warming ocean temperatures.

David Helvarg is the author of the new book "Forest of the Sea: The Remarkable Life and Imperiled Future of Kelp."

Helvarg joined Midday Edition Monday to talk about what kelp forests add to our oceans, the history of the Point Loma kelp forest, as well as restoration efforts to bring kelp forests back.
