Ecological Problems
Ecology is a science about nature surrounding us.
The main ecological problems are:
Slide 3
Many rivers and lakes nowadays are polluted with different waist products, which are very harmful for plants and animals living in them. Some species are extinct today. Water in the majority of rivers and lakes has become undrinkable.
In big industrial towns and cities the air is very dirty. Sometimes people have to close the windows not to let it in. When it is not windy smog is hanging over the city and people breathe in poisonous substances.
Some waist products are buried in the ground, they poison soil and make harm to the plants which grow on it.
Slide 4
Where Does Acid Rain Come from?
People have left on the Earth for thousands of years. They tried to make their life safer, easier and more comfortable. They have built big houses, huge factories and plants, lots of different cars and machines and power stations.
Slide 5
Where Does Acid Rain Come From?
The smoke from cars, factories and power stations go into the air. This smoke contains sulfur dioxide and nitrogen oxide. These substances mix with water vapor in the atmosphere and form sulfuric acid and nitric acid. Sunlight turns these acids into poisonous oxidants which fall in rain or snow onto the trees.
Slide 6
How Does Acid Rain Influence Trees?
Acid rain influences deciduous trees like oak, beech and birch as well as coniferous trees like fir and pine. First the branches turn yellow and brown. Then the trees" needles or leaves fall. The roots and trunk shrink. Finally the trees die. In the Black Forest in southern Germany 75% of the trees have been damaged or killed.
Slide 7
Why Are Trees So Important?
Trees are important because they provide a home for many other plants, and animals too. They protect the flowers which grow on the forest floor. They provide food for insects, reptiles, birds and mammals. They protect the soil from the wind and the rain. Most important of all, the forests are the lungs of the planet. Trees produce the oxygen which we breathe. If the trees die, we will, too.

Environmentmen t al questions
- What does the life of the people on Earth depend on?
- Why are some animals and birds disappearing nowadays?
Air pollution is a very serious threat to our environment.
pollute the air.
- This is the result of human activities: oil spills. Polluted water also causes water animals to die.
- Environmentalists are worried because many coral reefs are disappearing. Today only 7% of Jamaica’s coral reefs remain and the reefs in the Philippines and Western Indonesia are almost extinct. Tourists damage reefs by putting
- rubbish into the sea.
Ecological situation in our place.
- I’m worried about the state of the Nekhvoroshcha-novka pond in my area. When I visi-
ted this place in summer I was hurt and disap- pointed by what I found. Water was very muddy.
Our attitude towards the environment.
We must keep our native place clean. If we see litter on the ground, we must put it into a litter bin. And of course we must not draw on walls
- We must keep our native place clean. If we see litter on the ground, we must put it into a litter bin. And of course we must not draw on walls or trees.
Code of Ecological Rules.
- Do not leave litter.
- Keep the country tidy.
- Respect the life and work of the countryside.
- Grow trees and flowers.
- Do not cut wild flowers.
- Put litter away.
- Do not frighten birds and animals.
- Do not burn fires.
The Earth is Our Home.
- The Earth is a garden. It is a beautiful place For all living creatures, For all human race.
- Food is a treasure From the soil and the seas Clean fresh air From the plants and the heels.
- Helping mother earth We can peacefully roam We all deserve a place We can call our home.
- The warmth of the sun Turns water into rain It is nature way!

This word came from the Greek "oikos" which means "home" .
“ Home" includes:
- Its population
- Our whole planet
- Nature
- Animals
- Birds
- Fish
- Insects
- All other living beings
- And even the atmosphere around our planet.
What is the environment ?
It means what is around us.
Some people live in a town environment, for others their environment is the countryside.
The air we breathe, the soil on which we stand, the water we drink are parts of the environment.

problems
toxic air
Dangerous water
Polluted land
The air we breathe
- Every year the world industry pollutes the atmosphere with about 1000 million tons of dust and other harmful substances.
- Big cities suffer from smog.
- Cars with their engines have become the main source of pollution in industrial countries.
The water we drink
- Two-thirds of the world’s surface is water. Many seas are used for dumping industrial and nuclear wastes. Many rivers and lakes dry up or are poisoned too .
- Fish dies in the lakes, rivers and seas .
- If people drink this water, they can get ill or even die.
The land we live on
- People cut down trees and many birds and animals can’t have homes in their usual places and they begin dying out.
- As a result some species of animals, birds, fish and plants have disappeared and keep disappearing.
Environmental protection. What should people do to survive?
- The time has come to save our planet, to protect people, animals and plants from dying.
- First of all countries should have strong laws to control pollution, to protect animals and plants.
- Governments should also find ways to recycle things. They should build recycling factories.

Slide description:
Man-the child of nature We live on a very beautiful planet – on the Earth. Our planet has very rich resources: the bright blue of the sky, fresh, crystal-clear mountain lake water, the rich green of the mountain slopes, wild flower, picturesque views – all these scenes of nature fill us with admiration. That’s why those who live in cities prefer spending their days off and their holidays far from the noise of the city, to be closer to nature. Perhaps they like to breathe fresh air or to swim in clear water because the ecology is not so poor as in the cities.

Slide description:
Ecological problems Ecology is the study of the ways in which organisms (plants and animals) depend upon each other and upon their surroundings. Each organism requires conditions in order to be able to live and breed. These conditions are its environment by changing the ecological conditions.

Slide description:
So, pollution is one of the most burning problems of nowadays. Now millions of chimneys, cars, buses, trucks all over the world exhausted fumes and harmful substances into the atmosphere. These poisoned substances pollute everything: air, land, water, birds, animals and people. So, it is usually hard to breathe in the large cities where there are lots of plants. Everything there is covered with soot and dirt. It affects harmfully on people's health.

Slide description:
Water pollution is very serious, too. Ugly rivers of dirty water are polluted with factory waste, poisoned fish are all-round us. And polluted air and poisoned water lead to the end of the civilization. So, nowadays a lot of dead lands and lifeless areas have appeared. Because our actions and dealings can turn the land to a desert.
7 slide
Slide description:
The Baltic Sea is a special case. Because it is such a small sea and it becomes dirty very easily. Its waster changes slowly through the shallow straits. As many as 250 rivers run into the Baltic. There are hundreds of factories in these rivers and millions of people live along them. Quite a lot of big cities lie on its coast. All these combined with the active navigation of the sea naturally affects the state of the sea water and the shore line flora and fauna. People suffer from the waster pollution; cancer deaths increase people's concern.
Slide description:
And there is no escape from this ecological crisis without organizing a single body dealing with the environmental problems, developing and carrying out a national program of environmental protection and co-operating with international schemes.
Slide 9
Slide description:
Discourse about problem So, we see that our environment offers an abundance of subject matter for discussion. The problems and prospects of the blue planet interest not only scientists and futurologists, but also politicians, industry, the public – and above all, young people! There is hardly a young person who is not conserved with the preservation of our natural habitat. To recognize environmental problems and master them, to reduce and avoid environmental pollution, to discover and develop ecologically sound technologies – there are the essential building blocks for our future.

Slide description:
Population Fears Scientists now predict that by the year 2050 the population will be doubled what is today. The fact remains that the rate of food production fell behind population growth in many of developing countries. The annual fish catch already exceeds what the world’s oceans can successfully sustain. If we go on using our natural recourses at today’s rates, we will have used up the entire reserves of cooper, natural gas and oil by the year 2054.

Slide description:
But the problem ahead lie not so much in what we use but in what we waste. What faces us is not so much a recourse crisis as a pollution crisis. The only solution is to try to change the areas of consumption, technology and population. Changes in technology must be baked by slower population growth. And it can be achieved by education in health and women’s rights. And there is a little hope of reducing consumption over the next half century.
Slide description:
Nowadays there are many different pressures and interests groups in the world, which try to find solutions to the problems of pollution at the national and international level. So they are groups of people with a common interest in trying to draw the public attention to environmental problems, to influence the government decisions.
Slide description:
Ecological organizations There are many ecological organizations in the world, but I can tell you only about seven of them, because they are most famous. At first I’ll tell you about “Kids F.A.C.E”. The main mission of “Kids F.A.C.E” is to provide information, to encourage and facilitate youth’s involvement with effective environmental action. Membership of organization is free for all. “Kids F.A.C.E” started in 1989.

People have always polluted their surroundings. Even in ancient times people admitted that their health was depending on the state of surroundings. But only in XX century humanity, in full measure, realized that many diseases are closely connected with the air and water pollution and inferior products. People always pollute their environment. Even in ancient times, people admitted that their health depended on the state of their environment. But only in the twentieth century did humanity fully realize that many diseases are closely related to air and water pollution and poor-quality products.
Air pollution. Air pollution is a very serious problem, because polluted air can cause illness and even death. Every year the world industry pollutes the atmosphere with about 1500 million tons of dust and other harmful substances. Many cities suffer from smog, the oxygen balance is upset. Cars are polluting the air by exhaust gases and other dangerous chemicals. Air pollution is a very serious problem because polluted air can cause illness and even death. Every year, global industry pollutes the atmosphere with about 1,500 million tons of dust and other harmful substances. Many cities suffer from smog and the oxygen balance is disrupted. Cars pollute the air with exhaust fumes and other dangerous chemicals.
Water pollution Water recourses is one of the main factor of existing life in our planet. People use fresh water for their needs. It is more than 2% of hydrosphere volume. First of all water pollution is the result of industrial, agricultural and everyday necessities discharge of wastes into rivers, lakes and seas. The main part of water pollution plays a large number of oil industry wastes. Water resources are one of the main factors of existing life on our planet. People use fresh water for their needs. This is more than 2% of the volume of the hydrosphere. First of all, water pollution is the result of industrial, agricultural and domestic waste dumping into rivers, lakes and seas. Large amounts of oil industry waste play a major role in water pollution.
Soil pollution The main component of the Earth biosphere represents topsoil. Soil is polluted by: litter, wastes, heavy metals, pesticides, radioactive elements. Sinking aerosol may contain heavy poisonous metals and it may lead to plants ruin. The main component of the Earth's biosphere is the top layer of soil. The soil becomes polluted: garbage, waste, heavy metals, pesticides, radioactive elements. The lowering aerosol may contain toxic heavy metals and this may cause plant death.
