Question

Ocean ecosystems are sensitive to be chemical composition to water. Any excess compounds can upset the balance and cause damage to organisms. In three to five sentences, Describe how reducing consumption of fossil fuels can help the ocean ecosystem (4 points)

Answer 1

Reducing fossil fuel use cuts carbon dioxide emissions, which slows ocean acidification and helps shell-forming organisms (like corals, mollusks, and some plankton) maintain their calcium carbonate shells and skeletons. It also lowers greenhouse gas–driven warming, reducing ocean temperature rise that causes coral bleaching and disrupts species’ ranges and breeding cycles. Burning fossil fuels emits nitrogen and sulfur compounds that can deposit in coastal waters and fuel harmful algal blooms and hypoxic “dead zones,” so using less reduces those inputs. Finally, reduced extraction and transport of oil and petroleum products means fewer spills and toxic contaminants entering the sea, directly protecting marine life and habitats.
