Слайд 2 Greetings, dear viewers and readers. The problem of environmental pollution is
in the first place at present. Nature suffers and perishes, but we have a reason for that !!!
My name is Ksenia, and I want to show you how our world is suffering! We will look at important points in our lives.
Слайд 3The most important problems in this field are: the environmental pollution, ozone
layer depletion, diminishing water resources.
Слайд 4The first problem is environmental pollution caused by numerous industrial, chemical enterprises,
which do not refine their wastes,
Слайд 5as well as in emergency cases have no sewage purification, the result
of which is the pollution of reservoirs and water basins.
Слайд 6The second problem is garbage. Rubbish tips, dumped poisonous chemicals, broken cars,
thrown away bottles and dropped sweet papers are types of land pollution. Poisoned soil can make animals and people very ill.

The next problem is the depletion of the ozone layer, which is
also of great importance to people. For example, global warming is a consequence of the destruction of the ozone layer.
Слайд 8Doctors believe that as a result of the decrease in ozone, the
percentage of skin cancer and blindness due to cataracts has increased. The human immunity also falls, which leads to various types of other diseases. The inhabitants of the upper layers of the oceans are most affected.
Слайд 9Another source of environmental pollution is road transport. Oil-fired internal combustion engines
emit a lot of harmful gases. The most important environmental issues are nuclear power plants.
Слайд 10There are many consequences of damaging the environment: acid rain, water shortage
resulting from abuse of arable lands in agriculture, damage to wild-life. Vast forests are cut and burnt in fire. Their disappearance upsets the oxygen balance. As result a number of rivers and lakes dry up.
Слайд 11Drought leads to the death of animals, plants and even soil. Many
animals have to change their habitat.
Слайд 12Remember, the discharge of dust and gas into the atmosphere returns to
the Earth in the from «acid rains» and affects crop, the quality of forests, the amount of fish. To this can be added the rise of chemicals, radioactivity, noisy and other types of pollution.
Слайд 13You saw only part of how we kill life.
Think about it,
this is our home!
We can’t change our planet, as if to buy a new apartment when the old is no longer suitable for life.
We must save her!
Слайд 14 Our duty is to help to prevent pollution of nature !!!
