III Постановка целей урока.

• Children, what are we going to speak about today?

• You are right. We will speak about Ecology today. Ecology is a very popular word today. But what does it mean? Ecology is a science which studies the relationship between all forms of life on our planet and the environment. This word came from Greek “oikos” which means home. The idea of home includes our whole planet, its population, Nature, animals, birds, fish, insets and all other living beings and even the atmosphere around our planet.

1. Air Pollution

About 150 years ago the air was pure and clean. Then people started building factories and many of the things they makeput a lot of harmful gases into the air. Most of the pollution in big cities comes from cars and buses. Today the air is so polluted in some places that it`s not always safe to breathe there.

Polluted air is not only bad for people and animals, but also for trees and plants. And in some places it`s even damaging farmers` crops (сельскохозяйственные культуры) – the food we eat. So it`s very important for us clean up the air we all breathe.

To stop air pollution we must:

Save and protect forests because they are the lungs of our planet. Trees produce oxygen which we breathe.

Use public transport, as often as you can. Trams, trolley-buses and metro don`t pollute the environment.

Produce and use the cars which work on electricity.

Use good filters in our factories.

 Build factories for utilizing solid wastes

2) Water Pollution

The planet Earth is mostly water. Oceans cover the biggest part of it – and there are lakes, rivers, streams, and even water underground. All life on the Earth depends on the water.

There is no ocean or sea which is not used as a dump. They are used for dumping industrial and nuclear waste. Many rivers and lakes are polluted too. Factories and plants produce a lot of waste and pour it into rivers. Fish and reptiles can`t live in them. There is not enough oxygen in the water. In such places birds leave their habitats and many plants die.

To stop water pollution we must:

Use good filters in our factories.

Use less water:

- don`t leave the tap (кран)running when you brush your teeth;

- take showers not baths;

- wash the dishes by hand;

3) Land Pollution

When you throw something away, it goes into a garbage can.

Almost all garbage is taken to a garbage dump where it is put onto the ground. A big tractor comes along and pushes dirt on top of the garbage. So, most of our garbage is just buried. Now we are making so much garbage that in many places, there is not enough room to bury it all.

We dump domestic and industrial waste in the country and destroy the beauty of the countryside.

To stop land pollution we need to:

buy products with as little packing as possible;

use and throw away fewer carrier bags;

waste less paper;

turn rubbish into energy;

 buy recycled paper, recycle newspapers, cardboard, aluminium cans, glass jars and plastics.

4) Disappearing Animals

Every day there are more and more people living on the Earth. All these people need room to live. So they move into the places that are already homes for plants and animals. Forests are cut down, and wild areas are filled with houses and stores.

When people move into a new land, the plants and animals that live there can become endangered – which means they begin to disappear because there`s no place for them to live. Some even become extinct – which means that they all die out, and are gone from the Earth forever.

People continue to kill animals to wear fur coats. We kill many animals just for their fur.  Some of these animals, such as the fox, are in danger of extinction.  Every hour some kinds of animals and plants die.  

To protect wildlife we must:

organize conservation projects;

organize national parks;

fight against poachers

5) Deforestation

Of all the ecological problems today, one of the most serious one is deforestation. Forests are one of the greatest beauties our planet Earth has; yet, it is being destroyed every day all over the world. About one half of the forests that covered the Earth are gone. Each year, another 16 million hectares disappear. Vast forests are cut down in Africa, South America and Asia for the needs of industries in Europe and the USA.  The loss of the forests upsets (нарушает) the world's oxygen balance.  Many people think deforestation should be stopped. Trees and other plants take carbon dioxide from the atmosphere and release oxygen back into the atmosphere.

To stop deforestation we must:

• plant more trees to prevent global warming and make our country green

• make laws to protect forests

Заключение песня don`t kill the world

Don't kill the world
Don't let her down.

Do not destroy basic ground.
Don't kill the world
Our means of life.
Lend ear to nature's cry.

Don't kill the world
She's all we have,
And surely is worth to save.
Don't let her die,

Fight for her trees,
Pollution robs air to breathe.
Don't kill the world
Help her survive

And she'll reward you with life
And don't just talk,
Go on and do the one, who wins is you.
Cherish the world,

A present from god
On behalf of all creatures,
Made by the lord
Care for the earth,

Foundation of life
Slow progress down help her survive

Ecology

We live on the earth. It is very, very big. There is a lot of water on the earth. It is in rivers, lakes, seas and oceans. There are a lot of forests and fields, hills and mountains on it. The earth is full of wonders. Different animals live on the earth. Different plants grow on it. The earth is beautiful.

People have lived on our planet for many years. People depend on their planet, on the sun, on animals and plants around them. People must take care of Earth. Our ecology becomes worse and worse with every new day. Many species of animals and birds are disappearing nowadays. People destroy (разрушают) wildlife, cut down trees to make furniture. They forget that people can't live without trees and plants, because they fill air with oxygen(кислород).

The main reason of pollution is rubbish. One of the ways to get rid of rubbish is to burn it but the fires pollute the air. Another actual problem is protection of wildlife as a lot of animals disappear every year. People kill animals for different aims: e.g. people hunt whales for their meat and oil; elephants for their tusks (бивни), crocodiles for their leather(кожа) and so on. Modern life is bad for animals, birds, fish. The air isn't fresh and the water isn't pure. They don't have good meal and conditions for life. You can find their names in the Red Book.

The planet Earth is only the only place where human beings can live. Today, our planet is in serious danger. Acid rains, global warming, air and water pollution, overpopulation are the problems that threaten (угрожают) human life on Earth.

The seas are in danger. They are filled with industrial and nuclear waste, chemicals. If nothing is done about it, one day nothing will be able to live in the seas. Every ten minutes one kind of animal, plant or insect dies out for ever. If nothing is done about it, one million species that are alive today may soon become extinct.

Air pollution is another serious problem. Factories emit (выделять) tons of harmful chemicals. They are the main reason for the greenhouse effect and acid rains.

Fortunately, it's not too late to solve these problems. We have the time, the money and even the technology to make our planet a better, cleaner and safer place. We can plant trees and create parks for endangered species. We can recycle litter. We can support green parties. Together we can save the planet.
