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. Ships are the main contributors to ocean pollution, especially when crude oil spills occur. Crude oil lasts for years in the ocean and is difficult to clean.
Every year, billions of pounds of trash and other pollutants enter the ocean. Where does this pollution come from? Where is he going? Some of the debris ends up on our beaches, washed away by waves and tides. Some debris sinks, others are eaten by marine animals that mistake it for food, and others accumulate in ocean gyres. Other forms of pollution that affect ocean health come from sources such as oil spills or from the accumulation of many scattered sources, such as fertilizers in our gardens.
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. The rate of plastic that is dumped into the oceans increases simultaneously with the increase in the human population. 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. Although it is intentionally released into the sea, wastewater also contributes to ocean pollution, as well as to plastic products.
The debris that forms garbage patches can be found from the surface of the ocean to the bottom of the ocean. So-called “biodegradable” plastics often only break down at temperatures higher than what will be reached in the ocean. The animals most vulnerable to damage caused by plastic waste in the ocean are dolphins, fish, sharks, turtles, seabirds and crabs. Low oxygen levels in the ocean cause the death of marine animals such as penguins, dolphins, whales and sharks.
As excess waste in the ocean slowly degrades over many years, it uses oxygen to do so, resulting in less than 02 in the ocean.
