Act now to stop ocean acidification, sometimes called global warming's evil twin. The Environmental Protection Agency is seeking public input on how to address ocean acidification under the Clean Water Act -- a process that opens the door to greater opportunities to regulate the emissions that are causing ocean acidification. It is extremely important that the EPA hears from you in support of these efforts. 

Our thirst for fossil fuels is turning our world's oceans more acidic -- with potentially devastating impacts on marine ecosystems. The oceans absorb about 22 million tons of CO₂ daily, causing seawater to become more acidic. Ocean acidification prevents crucial marine life such as plankton, shellfish, and corals from building the protective shells they need to survive.

Leading scientific experts warn that if we do not rapidly reduce atmospheric CO₂, our oceans will dramatically change and entire ocean ecosystems could unravel from the bottom up due to acidification. It’s not too late to act, but time is short.

The Clean Water Act -- our nation's strongest law protecting water quality -- provides tools that can be used to rein in CO₂ pollution. The law has a history of successfully reducing water pollution, including other atmospheric pollutants such as mercury and acid rain. The EPA has the ability to invoke this powerful law to curb CO₂ emissions that are causing our oceans to acidify.
