General Information
  • Man is facing an ecological crisis. For
    centuries he thought little about the
    consequences of the pressure he was placing upon
    nature. Today the by-products of man's activity
    can be compared to the results of global
    geological processes. The pollution of the
    atmosphere, rivers, lakes, seas and oceans has
    reached a dangerous level.
  • Some of these ideas contain important
    constructive elements. It is as clear as day that
    as long as mankind continues to exploit nature in
    a blind barbarous way, it will be constantly
    threatened by ecological ruin. The solution to
    every problem of nature conservation, is becoming
    complicated and costly.
  • These problems multiply with the development of
    every new oil deposit, the opening of new coal
    mines, the building of railways and power
    stations. That is why money and effort invested
    in conservation are vital.
  • 1. What kind of crisis is man facing?
  • 2. What is the result of mans activity?
  • 3. Why money and effort invested in conservation
    are vital?

7
Ecological Problems
  • For centuries our humanism has been developing
    in a lop-sided manner proclaiming man the lord
    and the king of nature and not the child. Human
    achievements in conquering nature are so great
    that the economic activity has an increasingly
    negative effect on the biosphere.
  • Biodiversity describes the variety of life over
    a wide spectrum of levels. Human activity is
    causing serious destruction of biodiversity at
    all of these levels. If we lose variety within a
    system, will the system be able to keep going in
    a similar way? The "rules" of evolution game are
    well-known. The winners are the "fittest", the
    losers are the "less fit". But today animals and
    plants perish not so much due to their physical
    extermination as due to the production of
    chemical and other industrial pollutants.
  • We all want a higher quality environment for
    ourselves. Just as we now demand higher standards
    of healthcare, or education, or public service,
    we increasingly feel we have a right to a high
    quality environment. The first step is to know
    what your rights and responsibilities are.
  • 1. In what way does man conquer nature?
  • 2. Are there any systems and rules concerning
    biodiversity?
  • 3. What do we need at last?

8
Ecological Situation Nowadays
  • 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.
  • So, pollution is one of the most burning
    problems of nowadays. Now millions of chimneys,
    cars, buses, trucks all over the world exhaust
    fumes and harmful substances into the atmosphere.
    These poisoned substances pollute everything
    air, land, water, birds and animals. So, it is
    usually hard to breathe in the large cities where
    there are lots plants. Everything there is
    covered with soot and dirt.
  • 1. What does the word ecology mean?
  • 2. What country did the term ecology come from?
  • 3. What may the reason of polluted atmosphere be?

9
Animals In Danger
  • Environmental protection is one of the main
    problems of today. Industrial civilization is
    characterized by numerous factories and power
    stations, automobiles and airplanes.
    Technological progress improves people's lives,
    but at the same time it causes numerous problems
    that were unimaginable in the past centuries.
  • The blue whale is the largest animal which has
    ever lived. It is three times heavier than the
    biggest dinosaur. By 1963 their population had
    been reduced to just 1000. Today it is even less
    than that. The African elephant is the world's
    largest animal. In 1970 there were about 3.3
    million of them living in the wild.
  • We, people, are the only species that can
    change the world, and we are the only species
    that can choose either to look after our world or
    to destroy it.
  • 1. What is industrial civilization characterized
    by?
  • 2. What species of animals are In great danger
    nowadays?
  • 3. Who is responsible for our world?

10
Disappearing Life
  • Vast regions of the Earth have plenty of
    sunshine and rain. This hot, wet climate makes
    trees and plants grow quickly, forming huge dense
    forests. They are called tropical rain forests.
  • Meanwhile, what is happening to the plant and
    animal life there? Animals, having lost their
    food and home, move on to the remaining forests.
    They are followed by other animals in the food
    chain. Soon, the remaining forest is overcrowded
    and is unable to support all the animals. What
    happens next. The land that has been cleared from
    the forests is used for farming. But, without the
    protection of the trees, the soil quickly dries
    out and soon it is worn out.
  • So what can be done to save tropical rain
    forests? There are two ways to prevent them from
    disappearing altogether. One way is to stop their
    cutting down. The other way is to replant trees
    on the land that has been cleared.
  • 1. What are tropical rain forests and what can we
    value them for?
  • 2. What is happening to the wild life there and
    what does it mean?
  • 3. What should be done to save the forests?

11
Environmental Protection
  • Air pollution is the result of mans use of
    chemicals, and is a common hazard in both
    industrial and developing countries.
  • One form of air pollution is acid rains. Acid
    rain results from the release into the atmosphere
    of sulfur oxide and nitrogen oxide. Electrical
    plants, industrial boilers and automobiles are
    among chief sources of these emissions. The gases
    react with water droplets, forming a mixture of
    sulfuric acid and nitric acid, this mixture
    returns to earth in the form of acid rain, mist
    or snow. Acid rain is killing vast stretches of
    forests in Canada, the United States, and central
    and northern Europe. Acid rain has acidified
    lakes and streams making them unable to support
    fish, wildlife, plants or insects.
  • Scientists predict that by the year 2025 the
    population will rise to 8,5 billion, and by the
    year 2050 it will double. Most people find these
    figures alarming. They are afraid that we will
    run out of land, energy and minerals. Optimists
    are sure that new generations will find a way
    out.
  • 1. What is air pollution the result of?
  • 2. What do you know about acid rains?
  • 3. What awaits us in the nearest future?

12
Land Pollution
  • Both human activities and natural events cause
    land pollution. Soil contamination is often the
    first stage of ? chain of events that lead to air
    and water pollution. Major contributors to land
    pollution include chemical plants, oil
    refineries, nuclear waste dumps, garbage dumps,
    corporal animal farms.
  • What are the sources and impacts of litter
    pollution? Residential and commercial communities
    contribute to land, air and water pollution when
    motor oil, antifreeze, household chemicals,
    pesticides and fertilizers drain into soil and
    water.
  • You can participate in land, water, and air
    pollution prevention by following these tips 1.
    Reduce. 2. Reuse. 3. Recycle. 4. ?void chemicals
    in your home and yard. Substitute green cleaning
    practices for chemical cleaners. If you do use
    household chemicals or fertilizers, dispose of
    them safely.
  • 1. What are main contributors to land pollution?
  • 2. What are the sources and impacts of litter
    pollution?
  • 3. How can we participate in land protection?

13
Greenhouse Effect
  • Carbon dioxide is not very poisonous and it is
    present in the atmosphere in so small a quantity
    that it does us no harm. But here is what this
    apparently harmless and certainly essential gas
    is doing to us. The sea level is rising very
    slowly from year to year. Eventually many cities
    will be drowned.
  • The concentration of carbon dioxide in the
    atmosphere is going up steadily. This means that
    in the coming decades Earths average temperature
    will go up slightly. The glaciers will retreat,
    the mountain tops will grow more bare, and the
    polar ice caps will begin to melt. It will drip
    down into the ocean and slowly the sea level will
    rise.
  • What is to be done? First, we must save our
    forests, and even replant them. We must have new
    sources of fuel. For example, nuclear fission.
    There is also the energy of waves, tides, wind,
    and the Earths interior heat. Most of all, there
    is the direct use of solar energy.
  • 1. What are the consequences of the increase of
    the concentration of carbon dioxide in the
    atmosphere?
  • 2. Why is it dangerous if Earths average
    temperature goes up?
  • 3. What should we do concerning the problem of
    the greenhouse effect?

14
Radioactive Contamination
  • ULTRA-VIOLET EMANATION is electromagnetic
    waves, which length varies from 0,1 to 0,4 micro
    meter. NEGATIVE ASPECT the influence of UV waves
    on the skin eyes may be destroyable. Eye skin
    diseases, violent burns skin cancer (that is
    melanoma), other biological effects are proven
    consequences of redundant intensity of UV
    radiation.
  • ATOMIC POWER STATIONS ARTIFICIAL RADIOACTIVE
    SUBSTENCES which appear as a result of nuclear
    weapon tests are also important sources of
    radiation. Nowadays they are very important
    producers of energy.
  • In recent years the pollution problems have
    received great publicity. The environmental
    movement has gained widespread trust support.
    The protection of natural resources wildlife is
    becoming a political program in every country. In
    the end of the XXth century atmospheric testing
    of nuclear bombs was stopped in different
    countries to prevent radioactive contamination of
    the atmosphere.
  • 1. In what ways can UV rays influence mans
    health?
  • 2. Do you think that people nowadays can live
    without nuclear power plants?
  • 3. What are the ways of protecting our Nature
    from radioactive contamination?

15
The Road To Destruction
  • Anger and stress are nothing compared to the
    real costs of the motor car over 3 thousand
    people die every year in road accidents in
    Britain 25 thousand deaths per year are caused
    by air pollution every seventh child in Britain
    suffers from asthma in London cars produce 99
    of all carbon monoxide in the atmosphere some
    types of cancer are related to traffic pollution
    traffic is one of the major causes of global
    warming and climate change.
  • And now some advice from Greenpeace how to
    solve these problems 1. Use your legs. 2. Use
    public transport. 3. Think before you go. 4.
    Share cars. 5. Dont believe adverts!
  • 6. Take action! There is always something we
    can do about the noise, pollution and danger of
    traffic. Talk to your neighbours, write to the
    papers, go to the town council, get a protest
    group together. Dont just sit around and
    complain!
  • 1. What is meant by the real costs of the motor
    car?
  • 2. What are the ways to improve our environment?
  • 3. Do you think that it is possible to stop using
    cars?

16
Noise Pollution
  • A number of experiments confirm that industrial
    and car noise has a negative influence on
    peoples health and make their lives shorter,
    because it is impossible to get accustomed to
    this noise. A person may not notice sounds, but
    it doesnt save him from problems with ears.
  • Cars give about 80 of noise. Japan is one of
    the noisiest country in the world. 82 of the
    population live in such regions where industrial
    and car noise is higher than it should be.
  • Many young people who listen to loud music may
    become deaf. This conclusion was made by Swedish
    and Japanese specialists, when they examined
    students and senior schoolchildren. Scientists
    try to make cars less noisy, airports and plants
    are built in some distance from the cities.
    People have to observe some rules to reduce noise
    in flats.
  • 1. Is it possible to get accustomed to the noise?
  • 2. How many people in Japan live in regions where
    car and industrial noise is higher than it should
    be?
  • 3. What conclusion was made by Swedish and
    Japanese specialists?

17
Light Pollution
  • Night satellite photographs of the Earth from
    space show that light pollution fills the night
    sky all over the world. Until recently, bright
    night skies were ?n issue ??l? for scientists and
    astronomers. Today, light pollution is ? public
    concern that affects wildlife, ecosystems, human
    health, and the financial well-being of
    communities.
  • Unlike most pollution, light pollution is not
    persistent. Turn the lights off, and the dark sky
    comes back immediately. Mitigating light
    pollution, however, has proven to be particularly
    difficult.
  • One solution to light pollution problems is to
    control poor night lighting with laws codes or
    ordinances. Local officials can cite ?nd
    prosecute those who violate these codes. You can
    do your part by learning more about light
    pollution and taking steps to reduce the
    extraneous night lighting in your own backyard
    and town. These steps wi11 save you money ?n
    electricity bi1ls and help mitigate the world's
    energy crisis.
  • 1. Where is light pollution most clearly seen
    from?
  • 2. What is the difference between light pollution
    and other types of pollution?
  • 3. How can we reduce light pollution?
