How does a person change the aquatic environment?

Water is an irreplaceable part of life, not only for humans, but also for all land and sea animals. With the advent of man, the aquatic environment has changed significantly and is changing to this day. Man reduces the amount of water, pollutes the oceans and rivers with chemical waste and poisons, and catches a huge amount of fish from the seas and oceans. Because of man, the marine fauna is changing and depleting. Many marine animals die, some species are on the verge of extinction. Often because of man, oil is released into the oceans and seas, which irrevocably poison the water.
