Once abundant along the entire west coast of North America, sea otters were hunted to the brink of extinction. A small population has recovered off the coast of central California, yet they have failed to expand their range. Cassandra Brooks interviews Tim Tinker and Jim Estes to find out why visitors at Point Reyes will not likely see California sea otters today.

The Point Reyes peninsula is considered by some to be one of the fog capitals of the universe. But recent studies have indicated that the fog is declining from the California coast. Cassandra Brooks interviews Mike Vasey and Todd Dawson about how this decline may impact area vegetation and ecosystems.

Black Abalone is one of seven abalone species found in California's intertidal
waters. But, due to dramatic population declines as a result of overfishing and withering syndrome, Black Abalones have been classified as critically endangered by the IUCN. Cassandra Brooks interviews Amy Henry, an intern looking for Black Abalones in the Golden Gate National Recreation Area and Point Reyes National Seashore. -
Phytoplankton form the base of the ocean's food chains transferring energy from
the sun to sustain the global ocean. These tiny floating plants account for half of
the photosynthetic activity on Earth. They also generate the majority of our fossil
fuels. Cassandra Brooks interviews Ivano Aiello, a geological oceanographer at Moss Landing Marine Laboratories, about how we burn ancient life to power our civilization and some of the issues that result from fossil fuel pollution. -
More than a hundred thousand marine species build their bodies using calcium carbonate. This incredible diversity of life evolved over millions of years, as animals figured out ways to pull calcium and carbonate ions from the water to build shells and skeletons. But all of this is changing. Our addiction to fossil fuels and the billions of tons of carbon dioxide we're pumping into the atmosphere each year may be undoing millions of years of evolution in a geological blink of time.
