How does pollution in the ocean affect the organisms?

Marine pollution occurs when harmful, or potentially harmful, effects result from the entry into the ocean of chemicals, particles, industrial, agricultural, and residential waste, noise, or the spread of invasive organisms. Air pollution is also a contributing factor by carrying off pesticides or dirt into the ocean.
