What are the 5 main sources of ocean pollution?

Opt for reusable bottles and utensils. Marine pollution is a combination of chemicals and garbage, most of which come from land-based sources and are washed away or washed into the ocean. This pollution causes damage to the environment, to the health of all organisms and to economic structures around the world. Chemical pollution is the introduction of harmful contaminants.

The most common man-made pollutants that reach the ocean include pesticides, herbicides, fertilizers, detergents, petroleum, industrial chemicals, and wastewater. So-called “biodegradable” plastics often only break down at temperatures higher than what will be reached in the ocean. Scientists found plastic fibers in corals in the Atlantic Ocean and, more worryingly, they discovered that corals ate more plastic than food. The Pacific garbage patch is an example of this type of collection, with plastics and microplastics floating above and below the surface of swirling ocean currents between California and Hawaii, in an area of approximately 1.6 million square kilometers (617,763 square miles), although its size is not fixed.

These areas look less like garbage islands and, as the National Oceanic and Atmospheric Administration says, more like microplastic pepper specks that swirl around an ocean soup.
