Marine pollution is a growing problem in today’s world. Our ocean is being flooded with two main types of pollution: chemicals and trash.
- Marine pollution is a combination of chemicals and trash, most of which comes from land sources and is washed or blown into the ocean. This pollution results in damage to the environment, to the health of all organisms, and to economic structures worldwide.
- 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.
- Marine trash 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. In this way, the microplastic pollution migrates up the food chain, eventually becoming part of the food that humans eat.
Causes of Marine Pollution:
There are many causes of marine pollution. Of all the facts, there is one constant: most pollution in our oceans begins on land and is caused by humans. Here are some of the major causes of marine pollution:
- Nonpoint source pollution (Runoff)
- Oil spills
- Ocean mining
- Harmful to marine animals
- A threat to human health
- Reduce chemical fertilizer use
- Opt for reusable bottles and utensils.
- Hold a cleanup
- Properly dispose of plastics and trash
Solutions for marine pollution:
- Prevention and cleanup.
- Reduce Your Use of Single-Use Plastics
- Recycle Properly
- Participate In (or Organize) a Beach or River Cleanup
- Support Bans
- Avoid Products Containing Microbeads
- Spread the Word
- Support Organizations Addressing Plastic Pollution
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. Many types of debris (including some plastics) do not float, so they are lost deep in the ocean. Plastics that do float tend to collect in large “patches” in ocean gyres. 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.
