How does a person affect the underwater world?

Unfortunately, man does not use the resources of the ocean economically and pollutes it. Marine vessels dump recycled fuel into water, industrial enterprises – hazardous production wastes. Therefore, oil products, detergents, radioactive substances, pesticides, and salts of heavy metals get into the water. The aquatic flora and fauna suffer from this. Birds, marine life and plants die. From lack of food, organisms change their habitat. Also, from human activity, the number of marine life and plants decreases.
