k|ltlaDa Nature reflects our nature The World Is Dying We Are Drowning In Plastic Worldwide, about 2 million plastic bags are used every minute. This might seem like an unbelievable number but according to Ecowatch, between 500 billion and 1 trillion plastic bags are used worldwide annually. With the largest population, China produced the largest quantity, nearly 60 million tonnes. China was followed by The United States at 38 million tonnes, Germany at 14.5 million tones and Brazil at 12 million tonnes. According to The United Nations, ingestion of plastic kills an estimated 1 million marine birds and 100,000 marine animals each year. Additionally, more than 90% of all birds and fishes are believed to have plas- tic particles broken up into tiny sizes in the ocean and consumed by these fishes, birds and aquatic life forms. Research conducted by Plymouth University suggests that close to 700 species of marine life are facing extinction due to the increase in plastic pollution. Everybody uses plastics; things made up of plastics as well as the things wrapped up in plastic. There are many types of plastic and they are all light and low cost and can be used in all weather. And they last long, really long. But the funny thing is we don’t usu- ally use plastic that long. We throw away plastic cups, bottles, chips, wrappers, straws, etc. and that too im- mediately after their single use. Plastics are made up of chemicals that don’t easily decompose. If anything, plastics take a really long time to degrade and within that time it causes a lot of damage. These things have led to a high prominence of plastic pollution in the environment. Plastic pollution can afflict land, water- ways, and oceans. It is estimated that 1.1 to 8.8 mil- lion metric tons of plastic waste enter the ocean from the coastal community each year. Living organisms, especially marine animals are harmed by this be it mechanical effects such as entanglement in plastics, or through exposure to chemicals, or ingestion of plastics. Humans are also affected by plastic pollu- tion such as disruption of the hormonal mechanism. composition has slowed down. It is estimated that the decomposition of a foam plastic cup will take 50 years, a plastic beverage holder will take 400 years, a disposable nappy will take 450 years and a fishing line will take 600 years. Plastic pollution has been described as being highly detrimental to large marine mammals. Some marine species such as sea turtles have been found to contain large proportions of plas- tics in their stomach. When this occurs, the animal typically starves because the plastic blocks the ani- mal’s digestive tract. Sometimes, marine animals get trapped in plastics and nets and die there. Chlorinated plastic can release harmful chemicals into the surrounding soil which can then seep into groundwater or surrounding water sources and also the ecosystem. This can cause serious harm to the species that drink the water. Landfill areas contain microorganisms, nylon-eating bacteria, and flavor bacteria. These bacteria break down nylon through the activity of the nylonase enzyme. Breakdown of biodegradable plastics releases methane, a very powerful greenhouse gas that contributes significant- ly to global warming. What can you do to end plastic pollution? • Reduce your use of single-use plastics. • Make sure to recycle plastic. • Participating in or organizing a cleanup of your local beach or waterway. • Avoid products containing microbeads. Prabesh Baniya B.Pharmacy 1st year ( Batch-2018) Plastics themselves contribute to approximately 10% of discarded waste. Many kinds of plastics exist de- pending on their precursors and the method of their polymerization. Recent studies have shown that plastics in the ocean decompose faster than was once through, due to exposure to sun, rain and other environmental conditions, resulting in the release of toxic chemicals such as bisphenol A. However, due to the increased volume of plastics in the ocean, de- Nature and Social Concern Society 37
