Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.
Chemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons. This type of pollution occurs when human activities, notably the use of fertilizer on farms, lead to the runoff of chemicals into waterways that ultimately flow into the ocean. The increased concentration of chemicals, such as nitrogen and phosphorus, in the coastal ocean promotes the growth of algal blooms, which can be toxic to wildlife and harmful to humans. The negative effects on health and the environment caused by algal blooms hurt local fishing and tourism industries.
Marine trash encompasses all manufactured products—most of the plastic—that end up in the ocean. Littering, storm winds, and poor waste management all contribute to the accumulation of this debris, 80 percent of which comes from sources on land. Common types of marine debris include various plastic items like shopping bags and beverage bottles, along with cigarette butts, bottle caps, food wrappers, and fishing gear. Plastic waste is particularly problematic as a pollutant because it is so long-lasting. Plastic items can take hundreds of years to decompose.
This trash poses dangers to both humans and animals. Fish become tangled and injured in the debris, and some animals mistake items like plastic bags for food and eat them. Small organisms feed on tiny bits of broken-down plastic, called microplastic, and absorb the chemicals from the plastic into their tissues. Microplastics are less than five millimeters (0.2 inches) in diameter and have been detected in a range of marine species, including plankton and whales. When small organisms that consume microplastics are eaten by larger animals, the toxic chemicals then become part of their tissues. In this way, the microplastic pollution migrates up the food chain, eventually becoming part of the food that humans eat.
Solutions for marine pollution include prevention and cleanup. Disposable and single-use plastic is abundantly used in today’s society, from shopping bags to shipping packaging to plastic bottles. Changing society’s approach to plastic use will be a long and economically challenging process. Cleanup, in contrast, may be impossible for some items.
Nonetheless, many countries are taking action. According to a 2018 report from the United Nations, more than sixty countries have enacted regulations to limit or ban the use of disposable plastic items.

Perilous pollutants may contain various types of impurities including harmful chemicals, dissolved gases, suspended matters, dissolved minerals, and even microbes. All the contaminants reduce the level of dissolved oxygen in the water and affecting the lives of animals and human beings to a great extent. Dissolved oxygen is the oxygen present in water required by the aquatic system to continue the lives of plants and animals. However biochemical oxygen is the demanded oxygen by the aerobic micro-organisms to oxidize organic matters of wastes. Water pollution is caused by two means, one is natural water pollution ( due to the leaching of rocks, decay of organic matters, decay of dead matters, silting, soil erosion, etc ) and another one is man-made water pollution ( due to the deforestation, set up of industries near large water bodies, high level emission of industrial wastes, domestic sewage, synthetic chemicals, radio-active wastes, fertilizers, insecticides, pesticides etc )
