Question

Ocean ecosystems are sensitive to the chemical composition of the 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

Burning fossil fuels releases large amounts of CO2, which the ocean absorbs, causing acidification that weakens shells and skeletons of many marine organisms and disrupts food webs. Fossil-fuel-driven warming also heats oceans, contributing to coral bleaching, altered currents, and lower oxygen levels that stress marine life. Using less fossil fuel reduces the risk of oil spills and cuts other harmful emissions that can lead to eutrophication and pollution. It also lowers demand for petrochemical plastics, helping reduce marine debris that injures and kills wildlife.
