Humans are changing the ocean’s chemistry. Seawater absorbs much of the carbon dioxide we pump into the atmosphere; In addition, more carbon is entering the water from land-based sources. In coastal regions, runoff, stormwater and other pollution makes the situation worse.
The result is an increase in acidity that damages the basic building blocks of life needed by oysters, clams, corals and other animals to make their shells and skeletons.
Cold waters accelerate this dynamic; the impacts from ocean acidification are being seen right now in the Arctic and in the Pacific Northwest. Ocean Conservancy is working with partners across the United States to raise awareness of this threat to our coastal communities.
Local businesses, particularly shellfish producers in Washington and Oregon are feeling the harmful impacts of ocean acidification today. One family business in Oregon that supplies oysters to many growers discovered its oyster larvae were dying simply because they were unable to survive in more acidic ocean water.
At the same time, there is growing concern that these types of effects could be felt along the Atlantic Coast.
Shellfish growers on both coasts note the threat ocean acidification poses to their livelihoods as they struggle to keep businesses up and running. As the dangerous acidification trajectory continues upward, shellfish, including oysters, mussels and crabs, may soon become scarce on people’s dinner plates —and hard to come by for hungry ocean wildlife.
Ocean Conservancy is getting the word out to make sure people understand this complex ocean threat. We need to reduce our carbon emissions to tackle ocean acidification at its root.
There are also actions we can take locally to reduce runoff and support research investments to protect jobs, businesses and the unique way of life our coastal communities sustain. We’re working with partners and people on the front lines to create support for local and regional actions to address acidification.
Send a clear message to the FDA that GE salmon is a threat to our dinner plates and the very future of fish. Take action.
