Imagine a forest larger than the Amazon producing vast amounts of oxygen and home to over 1,000 species of wildlife that few know about. That鈥檚 the world鈥檚 kelp forests. In a matter of decades, a spectacular cold-water paradise thirty million years in the making is succumbing to our warming oceans. Kelp forests are one of Earth鈥檚 most wondrous and underappreciated marine habitats. Please join Book Passage (Corte Madera) in welcoming David Helvarg, author of Forest of the Sea.
