RECYCLING



(1) Recycling is a very important subject, and one that is becoming more so all the time. As we all know, it reduces waste and is good for the environment. But what do recycling centres do with the things we throw away? I found out some very interesting information.

(2) Recycling paper has been the biggest success. In 1990, in the USA, more than 20 million tons of paper were recycled and turned into birthday cards, cereal boxes, and hundreds of other things. Paper is the easiest material to recycle and, as David Dougherty of Clean Washington said, "You can use it six times over, then burn what's left to create energy."

(3) Wisconsin cow farmer George Plenty had the most interesting use for recycled paper: he uses it instead of straw in his barn. "It's cheaper than straw," he said, "but even if the price were the same, I wouldn't go back."

(4) Plastic is the hardest material to recycle, because there are so many different kinds, all of which need to be treated differently. At the moment, only two per cent of the plastic used in the US is recycled. But is does have its uses: one company uses plastic from recycled car headlights to make windows. In some ways they are better than normal windows, because they are much harder to break. Another company, Image Carpets, uses plastic to make carpets and rugs. A comment made by the manager showed us how attitudes towards recycling have changed. "We worried that people might refuse to buy the carpets if they knew they were recycled," said sales Manager, John Richmeier. "Now we advertise the fact as a marketing strategy."

(5) Metal is another important material. It is easier to recycle an aluminium can than to make a new one. It is also 20 per cent cheaper, and uses only 5 per cent of the energy that making a new can would use. So many of the things we use are made of metal, and can all be reused after they stop working. Recycling car parts, for example, is a big business. There is also very little waste involved in recycling metal. Steel is 100 per cent recyclable, and can be recycled hundreds of times. Recycling steel is cheaper than mining it. A lot of America's scrap metal is taken by the Japanese, recycled, and eventually sold back to America as new cars.

(6) 20 per cent of America's glass is recycled, and used for a number of things. For example, it can be mixed with asphalt or cement and used to pave streets. It can also be melted down and used to make new bottles. However, unlike the other materials, glass can also be reused commercially in its original form; many types of bottles are returned to bottling plants, sterilized and refilled. Recycling and reusing glass is actually a huge worldwide business, with bottle banks appearing everywhere.

(7) So remember, think before you throw things away — they may still be useful. If we all make an effort to recycle, we can make the planet a cleaner place to live.

Our Earth is Our Home”

The environment is all the things we need to be able to live - clean water to drink , air to breathe and healthy food to eat.    We can’t live without plants and animals. They help to make the soil, they clean the water and air, and they give us all our food.

Rainforests are very dense, warm and wet forests. Rainforests are found on every continent across the Earth, except Antarctica. They cover only 6% of the Earth’s surface but yet they contain more than a half of the world’s plant and animal species.

The Earth has been getting hotter because we are producing too  many greenhouse  gases.  Because the Earth is  getting hotter, ice is melting. Scientists say that in 2050 some parts of Great Britain will be under the sea.

Post-reading Stage Answer the following questions using the text.

  • What is the problem described here?
  • What is recycling?
  • Why do American farmers prefer using paper to straw?
  • What things can be made through the process of recycling?
  • Why is recycling so important nowadays?

We can recycle newspapers,  bottles and metal cans. We mustn’t cut down trees. Feed birds in winter. Protect wildlife, plants and trees. Keep all water clean. Don’t use aerosol sprays. Don’t use chemicals in the garden. Turn off the light when you leave the room. Don’t cut wild flowers. Try to avoid buying plastic. It’s hard to recycle.
