Слайд 1Global environmental problems and solutions
Слайд 2Problems
The destruction of a large number of species of plants
and animals
Deforestation
The rapid decline in mineral reserves
The depletion of the
oceans as a result of the destruction of living organisms
Pollution of the atmosphere, violation of the ozone layer
Pollution of the Earth's surface and disfigurement of natural landscapes
The rapid development of industrial enterprises
Global warming
Rapid population growth
Слайд 3The destruction of a large number of species of plants
and animals
Many species of plants and animals disappear
through the fault of people. In recent years, 10 to 130 different species disappear on Earth daily. This is more than new.
Animals whose number of species
dramatically reduced by the fault of man.
Слайд 4Deforestation
The disappearance of forests is a global environmental
problem. Deforestation of the planet leads to sharp temperature changes,
changes in the amount of precipitation and wind speed.
Слайд 5Mineral Cuts
The amount of mineral reserves is rapidly decreasing.
According to various sources, coal reserves will last for another
130-200 years, oil for 45 years, gas for 75 years, and iron ore for 65 years.
Слайд 6The depletion of the world's oceans
The ocean is
depleted as a result of the destruction of living organisms,
ceases to be a regulator of natural processes. The depletion of the world's oceans will lead to the depletion of other parts of nature.
Слайд 7Air pollution affects:
Atmospheric pollution is one of the main reasons
for the increase in the number of respiratory diseases, both
acute and chronic.
Forests, many agricultural plants — when they pollute the air, they either die or grow much slower;
Aggressive substances increase the corrosion of metal structures, acid rains appear, and ozone holes appear.
Слайд 8Ozone depletion
The ozone layer absorbs most of the ultraviolet
radiation from the sun, which is detrimental to terrestrial organisms.
The
consequence of the destruction of the ozone layer - most of the land animals and many land plants will die.
Слайд 9Pollution of the Earth's surface and disfigurement of natural landscapes
On
Earth, it is impossible to detect a single square meter
of surface, where artificial elements created by man would not be found. The disfigurement of natural landscapes and pollution of the Earth’s surface leads to disturbances in the primary structure of the planet, which in turn can lead to various natural disasters.
Слайд 10The rapid development of enterprises
The industry does not stand still,
it is rapidly developing, and with it the number of
industrial enterprises that pollute the atmosphere through the release of wastewater, toxic gases into the atmosphere, etc., increases.
Слайд 11Global warming
Global warming is a slow and gradual increase in
the average temperature on our planet, which is just being
observed now. Its impact on our planet can lead to the extinction of many species of animals and birds, to the appearance of the greenhouse effect, and quite possibly to the death of mankind.
Слайд 12Rapid population growth
The number of inhabitants of the Earth is
rapidly increasing every year, but at the same time the
amount of clean drinking water, minerals, etc. is sharply reduced. It can be concluded that humanity can disappear from the lack of vital resources.
Слайд 13Ways to solve environmental problems
The widespread use of clean energy
throughout the world
Exemption from oil addiction
Input effective power consumption
Developing a
population growth management policy
Compliance with the Kyoto agreement to reduce the greenhouse effect
Reducing the formation of carbon dioxide in power plants
