Carl Safina Studies 'Saving The Ocean'

From the Deepwater Horizon oil spill in the Gulf of Mexico to the radioactive isoptopes pouring into the waters off Fukushima in Japan, it's been a tough year for the world's oceans.

Marine biologist Carl Safina is an optimist, though. In his new PBS series "Saving the Ocean," Safina turns his attention on promising conservation efforts around the world, from rebounding cod stocks off New England, to an Islamic conservation movement in a poor fishing community in Zanzibar.

Safina joins us to talk about what's working in the effort to save the world's oceans.

Guest:

"Saving the Ocean" premiers in Boston on channel 2 Sunday at noon.
