module three Environment Listening Task You will hear in three different parts a radio talk on plastics as you listen to each Bart answered the questions based on it. I bought one. Listen to part one off the talk and complete the statements 123 by writing the correct yah in each blank. This is Radio Rainbow FM, Delhi at one or 2.6 megahertz. It's time for our weekly in Wyman programme ICO Watch. Today you'll hear a talk on plastics in our daily life by Dr P when Gopalan, a noted environmentalist and teacher Theo Hello, this is Dr B. Vina Gopalan on your favourite programme. Seiko Watch. Today I'd like to talk about plastics. There is plastic all around us. Equipment, instruments, utensils, clothes, packaging, toys, bottles, furniture, water pipes and tanks and even bubble comes just about everything today is made of plastic. Plastic has been with us for quite a while. It became well known in the 19 thirties and went on to be a major substitute for other materials like metals, wood and glass in the 19 forties, thanks to a great deal of publicity. Since then, it has steadily increased its influence over lives in 1976 plastic outstripped steel to become America's most widely used material. But to now listen to Part two off the talk and complete the statements foe to five by filling in the blanks with one or two words each. And that's where the problems with plastic began. We'll come to that and it later. But let's talk about what plastic is made off. Well, the basic raw materials that go into the making of plastic are petroleum and natural gas, but plastic and also be made from coal or, if need be, even from wood. As you know, all these are hydrocarbons of some form or the other. They are processed into a waxy, Moldable stuff called resin, which is shaped into finished plastic products we use in our daily life. About three. You will hear Part three off the talk now, as you listen, righty against the statements that are true on DH F against the ones that are falls environmentally. Plastic has a good deal to recommend it. For example, plastic requires only 1/10 of the energy required to produce aluminium, and it can be easily moulded into any shape. It is hard and strong enough to withstand pressure and temperature and can be an easy substitute of expensive metals and precious wood. But as I said before, therein lies the problem that plastic presents because it is cheap and easily available, more and more of it is being used. What happens to the plastic that is no longer usable? It results in huge waste that is hard to manage first, Unlike metals and wood and other natural materials, it does not decay and decompose easily. Second, benzene that is used to produce polyester and nylon can cause cancer. Third, we cannot get rid of plastic by burning it for doing so will release toxins like hydrogen cyanide on hydrogen chloride in the air. Besides, when burnt plastic releases, clouds of tiny fibres that can short circuit electrical equipment and installations. What's more, plastic easily catches fire and is the chief culprit of choked sewage pipes and polluted water bodies. You will now hear the complete talk as you listen. Please cheque your answers.
