Ocean Acidification

Primary tabs

Why is the ocean becoming more acidic?

The ocean has absorbed about a third of the excess carbon dioxide emitted by burning oil, coal, and natural gas. Seawater is now roughly 30% more acidic than it was at the start of the industrial revolution.  This is a big change for every living creature, from whales and lobsters to the microscopic organisms they eat, called plankton.

Why should we care?

  • Know where most of our oxygen comes from? Plankton.
  • Know who depends on oplankton for food or oxygen? Humans! Also, fish, whales, lobsters, coral and virtually all other living things.
  • Think trees produce our oxygen? They do, but plankton produce more.
