Слайд 4

Introduction
Our Earth is a beautiful home for living beings,

common for all the humanity forever.
The number of the planet’s population is in increasing constantly, but the technical progress not only for the people’s welfare, but also threatens the life itself. When people pursue great profits, they often act unwisely- destroy nature, pollute the environment. The poisoning of air, land and oceans is the fastest spreading disease of civilization.

Слайд 5

Air pollution
Air pollution is a community problem. Cars, trucks,

buses and airplanes are the worst polluters. They send partly burned gases into the air. Air can be also polluted by smoke and gases from factories. Dirt, smoke, and gases in the air may be carried away by wind and by air currents, or settle over as a blanket of smog.

Слайд 6

Water pollution
Water pollution is caused by dumping wastes into

lakes, rivers, and other bodies of water. Harmful wastes may also get into the soil or drain off fields that have been sprayed with pesticides. Pesticides are often used to kill insects and weeds in cities or on farms. Polluted water can spread many diseases.

Слайд 7

Radiation
Radiation has become one of the main problems. There

are some atomic power stations in our country. It is even a greater disaster for the world. We all remember about Chernobyl catastrophe and its tragic results. Many people, who fought against that fire and received a certain doze of radiation are invalids now.

Слайд 8

Earthquakes
Earthquakes is too difficult to forecast them
and

many scientists devote themselves to
protect our lives.

Слайд 9

The problem of forests felling
Our forests are disappearing because

they are
cut down or burnt. If this trend continues, one
day we won’t have enough oxygen to breathe,
we won’t see a beautiful green forests at all.

Слайд 10

The problem of biological variety
Every ten minutes one kind

of animals, plants or insect dies out forever. If northing is done about it, one million species that are alive today may soon become extinct.

Cheeta Snow leopard Koala

Animals from Red Book. WE MUST SAVE THEM!

Слайд 11

Global warming
Each time we burn gasoline, oil, coal, or

every natural gas, more carbon dioxide is added to the atmosphere. The greenhouse effect is what causing the temperate of the Earth to rise, and creating many problems that will begin to take place in the coming decades.

Слайд 12

The hole in the ozone layer
Ozone absorbs harmful ultraviolet

radiation which is produced by Sun. Ultraviolet radiation can damage cells of living things- plants, animals and people. The damage of ozone has been caused by complex chemical reactions involving chlorine and bromine.

How can we keep our earth clean?
Don’t buy drinks in plastic

bottles.
Save your family newspapers. Find out how
to recycle newspapers in your area.
Save water: the best time to water is early
is morning. If there is the leaky tap in your
house, get someone to fix them.
Turn off the lights when you leave the room.
Turn off the TV or stereo when you are not
watching or listening.
Don’t cut wild flowers.

The World Wildlife Fund
The WWF was founded in 1961. At first

it was a
small group of people who wanted to raise to save
animals and plants. Today the WWF was raised
over 35 million for conservation projects and has
created or given support to National parks in 5
continents. It has helped 30 mammals and birds to
survive.
There are a lot of nature centers in all the
countries of the world, such as: “Friends of the
Earth”, “Green peace”, “Trust” and many others.

Слайд 15

Way of get rid of solid wastes
Every day people

throw away amazing amounts
of garbage and trash. Trucks take the garbage to
the out-of-the-way places. Sometimes the trash is
burned, causing air pollution. But the more healthy
way to get rid of solid wastes is to spread them
over the land and pack them down. After that a
thick layer of earth can be put down over the
garbage and trees and grass can be planted.

Слайд 16

Removal and utilization of the rubbish
The problem of removal

and utilization of the
rubbish was solved in Japan in a very interesting
way. Careful Japanese people gather food and
industrial waste separately. And they press it in
blocks. Those blocks wear packed up near the cost
in the ocean. So the coast was built up and a new
territory was formed. Now on this land there is a
new town. It is called a town of the future.

to have it
John Golsworthy
Fortunately, it’s not too late to solve these problems. We can plant trees and create parks for endangered animals. We can recycle our wastes and persuade enterprises to stop polluting activities, because it is apparent that we are destroying our Earth and future.
