the promblem of plasticpollition and itd causes in china , India , thainland and bangladesh
Answers
Answer:
Plastic pollution is the introduction of plastic products into the environment which then upset the existing ecosystems in different ways. These pollutants cause environmental degradation and also affect different living organisms and their habitats negatively.
When plastic products accumulate in the environment, they begin to cause problems for wildlife, humans, and other living organisms. They create conditions that are not favorable for healthy living and proper growth. This is what is essentially referred to as plastic pollution.

Explanation:
Plastics play a vital role in our daily life. However, plastic debris in the marine environment has serious negative impacts on marine resources, fisheries as well as on the use of coastal areas for tourism. It is also a threat to our precious Blue Economy.
Globally, one million plastic bottles are purchased every minute. Around 8 million metric tons of plastics go into the oceans every year. Over 46,000 pieces of plastics are found in one square mile of ocean. The global production and consumption of plastics have continued to rise and it is estimated that by 2050, there will be more plastics than fishes in the world’s oceans.
The Bay of Bengal is rich in marine resources and produces 6 million tons of fish that correspond to nearly 4 percent of the total global catch. It is an important source of animal protein for nearly 400 million people in this region. But the Bay is heavily littered with plastics and huge amounts of plastic waste are found on the shorelines, on the seabed, and suspended in the water column. The corals of St. Martin Island are almost dead, littered with marine debris, plastic packages, and food wrap discarded by hundreds of tourists daily. The Bay of Bengal and the South China Sea are the new plastic hotspots in Asia. Every year about 2 lakh tons of plastics enter the Bay of Bengal from Bangladesh. According to the Earth Day Network of USA (2018), Bangladesh is the 10th most plastic polluting countries in the world. Population pressure, poor waste management practices and shipbreaking are primarily responsible for that. Every year, 60-65 ships are broken in Chattogram and Khulna.
Plastics can have a direct impact on animals, both through entanglement and ingestion that cause starvation or suffocation of wildlife. It also affects biota through leakage of harmful chemicals often contained in plastics or attached to them. Perhaps what is most disturbing is the fact that plastic has been found inside fish and large mammals in different parts of the world. For instance, a dead whale found in Thailand had 80 plastic bags in its stomach. Fishes of the Pacific coast are estimated to consume over 2,200 tons of plastic in a year. The disintegrated plastic can potentially be ingested by the humans when they eat seafood, resulting in a number of fatal diseases including cancer. It is of the utmost importance to minimise plastic pollution.
Microplastics, which are tiny pieces of plastic or fibres smaller than 5 mm, are even a more dangerous form of marine debris/litter. About 80 percent of marine litter is microplastics. Face wash, toothpaste, scrubs and anti-ageing creams contain thousands of microplastics per product. A single shower can result in 100,000 plastic particles entering the ocean. Microplastics (also known as microbeads) are too small to be retained by the filters used at sewage treatment plants. Fish and shellfish ing
