Hungry Ocean (1x8)

:

Oceans cover 70 percent of our planet and are one of the most important carbon sinks we have, but the phytoplankton that convertcarbon dioxide into living matter are declining – and many scientists believe that Climate Change is the culprit. Dr. Brian von Herzen of The Climate Foundation joins forces with some of the world's foremost oceanographers — Professor David Karl of the University of Hawaii and Professor Ricardo Letelier of Oregon State University — to deploy three wave powered pumps. They head into the huge swells of the North Pacific in an attempt to restore this critical natural mixing effect.
