Free 600 words essay on polythenes (plastic bags) positive and negative effects for school and college students.
Use of Polythenes has increased exponentially in our modern living. It has found space in every corner of our homes and offices, around the globe. It remains a consistent part of our lives in a daily routine. Polythenes are the most common type of plastics. They are formed by bonding many monomers to form polymers. Plastics are primarily used to make plastic bags, films, bottles, containers, shoe soles, decorative pieces, carpets, etc.
Polythenes (plastic bags) positive effects
There are a few favourable reasons for making Polythenes as the first choice of people round the globe. They are inexpensive and sterile. They are cheap and prevents contamination, thus they are found to be effective for medical purposes and for daily uses of storing water, food, etc. They are very light in weight and can be used for multiple purposes in our daily life. They are being widely used for packaging and storage of materials by many industries. In fact many industries have settled down to plastics from glasswares because of it being more profitable. They are conveniently mouldable and remain leak proof, thus, proving out to be the best material for packaging and storage.
Polythenes (plastic bags) negative effects
However, the world has started to recognise that the negative effect of plastics on the environment. The packagings used to carry material in the way of bags or bottles are thrown away by approximately one-third of the consumers into the environment, eventually adding to the environmental pollution. These discarded polythenes add up to the landfill or eventually reach the water sources, polluting both in return.
It has been reported that approximately 300 million plastic bags and up in the Atlantic ocean alone. There is no doubt that they possess danger to the sea life. When hunting mammals consume a plastic bag, it mostly results in its death. The plastic acts as a poison to the mammal leading their way to sudden death or a slow painful death. Apart from direct consumption, Polythene releases harmful chemicals into the soil when on land, thus making their way into water sources and affecting the aquatic life negatively.
The plastics hamper the natural progression of wildlife. Their presence leads to suffocation death of animals on land and prevents any improvement in soil nutrition. Land animals when ingest or inhale plastics, their deaths become certain.
Burning of plastics releases toxic gases in the environment adding to the air pollution which is not good for the inhalation of human beings especially children. Many polythene materials contain toxins like phthalates, BPA and flame retardants. These are further more poisonous and also more difficult to dispose off. They further absorb harmful pesticides like DDT, PCB and PAH.
Polythenes are non-disposable and non-biodegradable. The process required to recycle plastics is very expensive which is why it is not being practiced in most parts of the world. It does not melt down easily and it’s reuse for a long time is not practical. Consequently, they end up polluting the environment.
The world has begun thinking over the alternatives to polythene stuffs and it is not very inconvenient to use them. For example, paper bags, fibre bags, cloth bags, glass bottles, silver sheets, etc. However, even these options are not completely eco-friendly. Papers used to make paper bags come from trees and cutting down trees for making paper bags will also have negative impact on the environment. The reusable cloth bag is the best option available as an alternate and it is increasingly gaining importance in everyone’s life.
Hence, it may be inferred that the plastics are leading the world to a silent death. One really need to understand their real importance, not making it a way of life.
