The more it comforts us, the more we use it.
One suitable item for the above sentence is plastic. The word plastic springs from the Greek word ‘plastikos’ meaning ‘capable of being shaped or molded’. Plastics are polymers which are made up of monomers, similar to a series of paperclips or a necklace. Plastics are often broadly classified into two- thermoplastics and thermosetting plastics. Thermoplastics are the plastics which, once molded, are often remolded and recycled. for instance, polythene, PVC, polystyrene etc. Thermosetting plastics are the plastics which can't be remolded or recycled. If they're heated to recycle, they're going to burn. Unlike the thermoplastics they preserve their shape and strength even when heated. for instance, vulcanized rubber, Bakelite, melamine, etc.
Nowadays, plastics are used most that it's become an inseparable a part of our life. it's very inextricably linked to us. If you have a look at your house and count the amount of plastic items, you may be surprised to understand that about 95% of them will be plastic. We use it everywhere for everything from packaging to industrial machinery. it's the bottom, inexpensive, easy to use and handle, immune to corrosion, poor conductor of warmth and electricity and is well moulded. because of this very reason, plastic has become an inevitable part.
However, it has many disadvantages too. One main disadvantage is pollution. Pollution refers to all kinds of pollution in water, land and air. People after visiting and enjoying the sweetness of the ocean, they merely throw the waste in to the water and also the wastes contains plastics.
Many marine animals who lives there swallows this plastic and gets choked. Some gets entangled with the polythene bags. Land pollution is totally a different case where huge piles of plastics are dumped on the road blocking the way. It also pollutes the land by releasing toxic substances and gases, as it is non-biodegradable, which are very harmful. They can also harm the water which runs through the soil. So, What does people do?? To avoid that, people burn the wastes so that it doesn’t pollute the soil. But, by burning of plastic it pollutes the air by emitting carbon dioxide and other harmful gases. Another disadvantage is of polythene bags which are coloured using colorful dyes. When food items are kept in it, the food gets contaminated thereby wasting and polluting the food. There are many more and more disadvantages.
Due to this arising problem of plastics, scientists have come up with an answer for use of waste plastics. They have melted polythene, thermocol, polypropylene, polystyrene article by strong heating (100-160C). This melt exhibits good binding property. After mixing it with bitumen, it is used for road -laying. This method is simply a solution for the waste plastic not a way to get rid of plastics. After many years, when the roads degrade, this plastic can permeate the soil and pollute groundwater. The things children can do is to use the 4R’s Refuse, Reduce, Reuse and Recycle. Try refusing, reusing and recycling plastic. Reduce plastic by using cloth or paper bags. Nowadays, some biodegradable plastic has also been designed. It is used for the filling if medicines and as a thread to stitch wounds while injuries. Let us also bring awareness to the societies about the threat of plastics by hanging posters. Let us strive for a more robust place, a much better earth to measure in.
