why the ocean is going bad

The ocean absorbs about 30 percent of the CO2 emitted from human activities. As the volume of atmospheric CO2 grows, the ocean collects its proportionate share. To give you an idea of how much that is, in 2013, countries emitted nearly 40 billion tons of carbon. According to the World Meteorological Organization, that represents the biggest surge in CO2 concentration since 1984.
So what does more acid in the ocean mean? For one thing, it means less calcium carbonate. This mineral is a key ingredient in the shells of several marine species, and without it, fewer shellfish are surviving to adulthood. One oyster farm in Washington state reported that their oyster production declined by 42 percent in just 10 years. The tiny shellfish that feed Alaska's salmon stocks are also in danger to say nothing of the state's lucrative crab fishery.
