The oceans regulate our climate and store nearly 30% of human caused carbon dioxide emissions.
Solutions are to restore coastal wetlands, reestablish ocean ecosystems such as kelp forests and coral reefs. Other solutions are small scale ocean farms for seaweed and oysters. These help to permanently store carbon while addressing ocean acidification.
Challenges are ocean warming and acidification, loss of ocean ecosystems, and loss of coastal wetlands to development projects.
Impact: By restoring coastal wetlands 3.19 gigatons of carbon dioxide could be captured. Farming of seaweed, algae, oyster and clams can store huge amounts of greenhouse gases.
