The following 8 year old groundbreaking video documentary explores the startling phenomenon of ocean acidification, which will challenge marine life on a scale not seen for tens of millions of years since during the Paleocene–Eocene Thermal Maximum. Called the "other carbon problem", ocean acidification is now understood to actually be more dire than presented here.
Note: A hundred years ago, the oceans seemed invulnerable to harm from us. A hundred years from now, the oceans will be dying. All because of our 'unrelenting' use of the fossil fuels of coal and oil. The solution is our transitioning ASAP to the use of renewable energy sources.

The two main classes of phytoplankton are dinoflagellates and diatoms. Dinoflagellates use a whip-like tail, or flagella, to move through the water and their bodies are covered with complex shells. Diatoms, also, have shells...
