Marine pollution refers to the introduction of harmful substances into the ocean, which can damage marine ecosystems and affect human health. Common pollutants include plastic waste, oil spills, and chemicals from industrial activities. These pollutants can harm marine life, such as fish, sea turtles, and coral reefs, disrupting their habitats and food sources. The effects of marine pollution extend beyond the ocean. Contaminated seafood can pose health risks to humans who consume it, while polluted waters can impact coastal communities and economies that rely on fishing and tourism. Addressing marine pollution requires global cooperation and sustainable practices to protect our oceans for future generations.
