![]() ![]() Solutions for marine pollution include prevention and cleanup. In this way, the microplastic pollution migrates up the food chain, eventually becoming part of the food that humans eat. When small organisms that consume microplastics are eaten by larger animals, the toxic chemicals then become part of 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. Small organisms feed on tiny bits of broken-down plastic, called microplastic, and absorb the chemicals from the plastic into their tissues. Fish become tangled and injured in the debris, and some animals mistake items like plastic bags for food and eat them. This trash poses dangers to both humans and animals. Plastic items can take hundreds of years to decompose. Plastic waste is particularly problematic as a pollutant because it is so long-lasting. 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. Littering, storm winds, and poor waste management all contribute to the accumulation of this debris, 80 percent of which comes from sources on land. Marine trash encompasses all manufactured products-most of them plastic-that end up in the ocean. The negative effects on health and the environment caused by algal blooms hurt local fishing and tourism industries. 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. 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. Our ocean is being flooded with two main types of pollution: chemicals and trash.Ĭhemical contamination, or nutrient pollution, is concerning for health, environmental, and economic reasons. Marine pollution is a growing problem in today’s world. ![]()
