Reducing consumption of fossil fuels can help the ocean ecosystem by decreasing the amount of greenhouse gases released into the atmosphere. These gases contribute to global warming, which in turn leads to ocean acidification. This change in chemistry can harm many marine organisms, especially those with calcium carbonate shells like coral and shellfish. By reducing our reliance on fossil fuels, we can help mitigate these negative effects and protect the delicate balance of the ocean ecosystem.
