The Marine Mammal Center

Many marine mammals are harmed or critically injured by our trash in the oceans. But Jalena found one place that's on a mission to save these creatures. The Marine Mammal Center in Northern California rescues seals, sea lions, porpoises and other injured or sick mammals and thanks to the dedication of hundreds of volunteers, they are healed, cured, rehabbed and returned to their native habitat. And some of the volunteers are concerned teens.
