Final answer:
Oil spills in the ocean have significant environmental impacts, including reduced light and oxygen availability and damage to marine organisms. Strategies like hosing oil from beaches and using bacteria to degrade the oil are used for clean-up.
Step-by-step explanation:
Oil spills in the ocean have significant environmental impacts. The spilled oil covers the surface of the water, reducing the amount of light and oxygen that enters the ocean. This can lead to the death of marine organisms, including phytoplankton. Oil spills also limit the mobility of marine animals and can result in their death. Additionally, oil spills can cause damage to fauna. To clean up an oil spill, strategies such as hosing oil from beaches, using floating booms to corral the oil, and employing bacteria to solubilize and degrade the oil can be effective.
