Ecological problems
Air pollution is a community problem. Cars,
trucks, buses and airplanes are the worst
polluters. They send partly burned gases into the
air. Air can be also polluted by smoke and gases
from factories. Dirt, smoke, and gases in the air
may be carried away by wind and by air
currents, or settle over as a blanket of smog.
Air pollution
Water pollution is caused by dumping
wastes into lakes, rivers, and other bodies
of water. Harmful wastes may also get into
the soil or drain off fields that have been
sprayed with pesticides. Pesticides are
often used to kill insects and weeds in
cities or on farms. Polluted water can
spread many diseases.
Water pollution
Our forests are disappearing because
people fell and burn trees. If this trend
continues, one day we won’t have enough
oxygen to breathe, we won’t see a
beautiful green forests.
Felling of forests
Throwing
litter
in
urban
areas
promotes air pollution, people are choke
with pungent odor. Appear pests and
parasites which carry diseases and
allergies.
Throwing litter in urban areas
Radiation has become one of the main
problems. There are some atomic power stations
in our country. It is even a greater disaster for
the world. We all remember about Chernobyl
catastrophe and its tragic results. Many people,
who fought against that fire and received a
certain doze of radiation are invalids now.
Radiation
The main ways of reducing and total
elimination of air pollution are: development
and implementation of treatment filters in
enterprises, use of environmentally friendly
energy sources, waste production technology,
the struggle with car exhaust fumes,
greening cities and towns. Treatment of
industrial waste not only protects the
atmosphere from pollution, but also provides
additional materials and profits.
