When people think about the state of Maine, images of lobsters and lighthouses usually spring to mind. For the state of Maryland, people think of blue crab and the rivers feeding into the Chesapeake Bay. Both states are closely associated with rich maritime traditions, however a change in ocean chemistry is rapidly occurring that could jeopardize not only their maritime way of life, but also the jobs and economic benefits that the ocean and coastal waters provide.
Ocean acidification is caused by carbon pollution from factories, cars, and power plants being absorbed by the ocean, turning it more acidic. In fact, the ocean absorbs roughly 30% of all carbon pollution we put into the atmosphere, and local pollution running off from the land into coastal areas can make acidification worse. Animals that have shells, like oysters, clams, mussels and crabs have trouble surviving in increasingly acidic water. In the Pacific Northwest ocean acidification has damaged these animals, contributing to billions of baby oyster deaths, significantly impacting the hatcheries and oyster operations in these regions. The impact of ocean acidification on other animals, such as lobsters and fish, are not well understood.
