Underwater Wilderness: Creating Marine Protected Areas

The waters off the coast of California are some of the richest in the world. But declines in fish species have led state leaders to begin creating large protected areas, or "no fishing zones," similar to wilderness areas on land. Although controversial with some fishing groups, the idea is to protect entire ecosystems instead of single species. The hope is that a statewide network may help bring back fish, birds and marine mammals that are currently on the brink.
