Слайды и текст этой презентации
Слайд 2The most important problems in this field are: the environmental
pollution, ozone layer depletion, diminishing water resources.
Слайд 3The environmental pollution is called for the numerous industrial, chemical
enterprises, which do not refine their wastes and in emergency
cases have no sewage purification, the result of which is the pollution of reservoirs and water basins.
Слайд 5Rubbish 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.
Слайд 6
The problem of ozone depletion is also of great importance
for the people. For example, global warming is a consequence
of the destruction of the ozone layer.
Слайд 7One of the sources of environmental pollution is automobile transport.
The internal combustion engines which work on oil fuel exhaust
a lot of harmful gases. The most important problems for protection of nature are the nuclear power stations.
Слайд 8There 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 10The 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
