Recycling

"In the time it takes to read this, more than a million pounds of materials that could have been recycled will be thrown away all over California."—Californians Against Waste (CAW) Newsletter

We are running out of space in which to discard our garbage, and our current methods of disposing of it are endangering the environment. One solution to this problem is recycling.

Recycling is the process of collecting used materials and remanufacturing them into new products instead of throwing them away. This process is important because it reduces the trash in overcrowded landfills, salvages materials that we can use to make new products, and saves our natural resources.

Used products may be converted or reutilized in a number of ways. Paper is reprocessed into new sheets, glass is cleaned and remolded, and plastic is melted and formed into new products such as carpet backing, fence posts, and drainage pipes.

Recycling is being done worldwide. Japan recycles 95% of its bottles and 50% of its aluminum; the United States recycles only 20% of its bottles and 38% of its aluminum. In Germany a new law requires product manufacturers to create ways of reusing their packaging material.

Helping to solve the garbage crisis is something everyone can do if they just remember the three Rs: "reduce, reuse,andrecycle."

Business Goes Green!

Many cities around the world today are heavily polluted. Careless manufacturing processes em­ployed by some industries and lack of consumer demand for environmentally safe products have contributed to the pollution problem. One result is that millions of tons of glass, paper, plastic, and metal containers are produced, and these are diffi­cult to dispose of.

However, today, more and more consumers are choosing "green" and demanding that the prod­ucts they buy are safe for the environment. Before they buy a product, they ask questions like these: "Will this hairspray damage the ozone layer?" "Is the packaging biodegradable?" "Will it break down in a trash dump?" "Can this metal container be recycled or can it only be used once?"

A recent survey showed that two out of five adults now consider the environmental safety of a product before they buy it. This means that com­panies must now change the way they make and sell their products to make sure that they are "green", that is, friendly to the environment.

Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry la­bels to show that the product is green. Some com­panies have made the manufacturing of clean and safe products their main selling point and empha­size it in their advertising.

The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of "Buy it, use it, throw it away, and for­get it." The public pressure is on, and gradually business is cleaning up its act.

Text C. MAN THE LOSER?

The warming of the climate on Earth that could only be reg­istered by experts at the begin­ning of the century is obvious to everybody in our day. The process has been set off by the rising content of carbon dioxide in the atmosphere and is directly traceable to human activity: the burning of fuels, the spewing of industrial exhausts, the felling of forests, and erosion of farmlands. However, some of the carbon dioxide is effectively absorbed from the air by the ocean and the green plants on land. Who will win in this "competition" be­tween Man and Nature? What will happen to the global cli­mate in a longer run, beyond the turn of this century?

A mathematical model has been developed by some em­ployees of the Computer Centre of the Russian Academy of Sciences in an at­tempt to answer these ques­tions. The model is described by a system of 1,500 differen­tial equations using such vari­ables as amounts of carbon dioxide in the biomass of living plants and in humus. To obtain accurate results, the scholars divided the land mass on the geographical map into meshes measuring 4 by 5 degrees. They have taken in the mean annual temperature, rainfall, and plant production over the year, since these characteris­tics are influenced by the car­bon dioxide content in the at­mosphere. The analysis has been carried out for such re­gions as Europe, the tropical forests, Canada, the USA, and this country since 1860 and has been extended till the year 2000.

It turned out that carbon dioxide is absorbed in all the regions, the forests in the tem­perate zone of the Northern Hemisphere playing the most significant role in the process. However, up to 53 percent of carbon dioxide contributed by industrial exhausts remains in the atmosphere (in the tropical forest zone the figure is con­siderably lower, while in the temperate and northern re­gions it is rising continuously). Apparently, plants can no longer absorb these excessive amounts of carbon dioxide. According to some estimates, the capability of green plants on land to absorb carbon dioxide declined after 2000, and at some point be­tween 2000 and 2030 the land itself may become a source of carbon dioxide!

When this will happen, if at all, depends on many factors, in the first place, on the eco­logical strategy of mankind which appears to be climbing further out on to the limb.

Environment and Ecology

I. Make sure you can translate the following text both ways – from English into Russian and vice versa.

Ecology is the science of how living things are related to their environment. Many people all over the world are concerned about the ecology today. The word "ecology" came from the Greek which means "home". This idea of "home" includes the whole planet of ours. We must protect our planet from littering, air pollution, water pollution, de­struction of natural resources.	Экология — это наука о том, как живые су­щества связаны с окружающей средой. Многие люди во всем мире обеспокоены состоянием эко­логии в настоящее время. Слово «экология» произошло от греческого слова, которое означа­ет «дом». Это понятие «дом» включает всю нашу планету в целом. Мы должны защищать нашу планету от засорения, загрязнения воздуха, во­ды, уничтожения природных ресурсов.
We know that polluted air, land and water are harmful to plants, animals and people. Many terri­tories, lakes, rivers, seas, oceans and the atmo­sphere are polluted with all kinds of technological, chemical, nuclear and other wastes. Awful harm is caused to our home by nuclear tests, atom bombs and accidents on the atomic power stations.	Мы знаем: загрязненный воздух, земля и во­да вредны растениям, животным и людям. Мно­гие территории, озера, реки, моря, океаны и воздух загрязнены различными технологиче­скими, химическими, ядерными и другими от­ходами. Ужасный вред причиняют нашему дому испытания ядерного оружия, атомных бомб и аварии на атомных электростанциях.
How can we keep our earth clean?	Как мы можем сохранить нашу землю чис­той?
Don't buy drinks in plastic bottles. These bot­tles can't be recycled and plastic won't even de-grade. If you throw this bottle, it will still litter the earth for ever. Only buy water and other drinks in aluminium cans or glass bottles. Buy milk and juice in cartons. Glass, aluminium and carton can be recycled.	Не покупайте напитки в пластиковых бутыл­ках. Эти бутылки не могут быть переработаны, а сам пластик никогда не разрушится. Если вы выбросите такую бутылку, это загрязнит нашу землю навсегда. Покупайте воду и другие на­питки в алюминиевых банках или стеклянных бутылках. Покупайте молоко и сок в картонных пакетах. Стекло, алюминий и картон могут быть переработаны.
The energy saved from one recycled aluminium can will operate a television set for three hours. If you throw an aluminium can out of the train win­dow, it will still litter the earth up to 500 years later. If you throw the glass bottle you litter the earth for ever.	Энергия, сэкономленная при переработке од­ной алюминиевой банки, даст возможность работать одному телевизору в течение трех часов. Если вы выбросите алюминиевую банку из окна поезда, это загрязнит землю на 500 лет. Если вы выбрасываете стеклянную бутылку, вы загрязняете землю навсегда.

Environmental Protection

The twentieth century is known to be the century of the scientific and technological progress. The achievements of the mankind in mechanization and automation of industrial processes, in chemical industry and conquering outer space, in the creation of atomic power stations and ships are amazing.

But at the same time this progress gave birth to a very serious problem – the poisoning of our planet, its land, its air and water. The ecological harmony is disturbed. The seas are filled with industrial and nuclear waste, chemicals and fertilizers. The concentration of smoke in the air is so high in some industrial centers that it is deadly dangerous just to breathe there.

Many species of flora and fauna have disappeared. Some of them are on the brink of extinction, many have been put down into the “Red Book of Nature”. Every hour some kinds of animals and plants die out for ever.

Acid rains, the greenhouse effect, ozone depletion caused by harmful substances emitted by industrial enterprises are much spoken about.

Unfortunately some means of transport can be regarded as offenders in poisoning the environment.

Atomic power plants are worth mentioning as a grave threat to the environment nowadays. The pollution of the environment is hard to ignore.

The problem of environmental protection has become an extremely important part of political programmes in many countries nowadays.

The Environmental Movement had gained a lot of supporters long before our country joined it. Many laws and vital decisions on the problem have been adopted, many measures have been taken to protect our forests, rivers, lakes and seas.

However, the Mediterranean is already nearly dead; the North Sea is following. The Aral Sea is on the point of vanishing. The environmental problems have grown beyond the concern of a single country. Their solution requires the cooperation of all nations.

It is obvious, that only our joint effort will help to avoid a global catastrophe.

-Vladimir Shatalov,

quoted in The Home Planet, 1988

The greatness of a nation can be judged by the way its animals are treated.

-Mohandas Gandhi

The frog does not drink up the pond in which he lives.

-Indian Proverb

This we know. The earth does not belong to man, man belongs to the earth. This we know. All things are connected like the blood which unites one family. All things are connected.

Whatever befalls the earth befalls the sons of the earth. Man did not weave the web of life, he is merely a strand in it. Whatever he does to the web, he does to himself.
