Ecological problems
Since ancient times Nature has served Man, being the
sourse of his life. For thousands of years people lived in harmony with the
environment and it seemed to them that natural riches were unlimited.
But with the development of civilization man’s interference in nature
began to increase.
Among the most pressing problems are:
1) Global warning (глобальное потепление)
2) Greenhouse effect (парниковый эффект)
3) Littering, water and air pollution (industrial
waste-промышленные отходы)
4) Destruction of natural resources
5) Deforestation
·
Large cities
with thousands of smoky industrial enterprises have appeared all over the
world. Their activity pollutes the air we breathe, the water we drink, the land
we grow grain and vegetables.
·
Every year world
industry pollutes the atmosphere with millions of tons of dust.
·
Many cities
suffer from smog.
·
Vast forests are
cut down and burned in fire. As a result some rare species of animals, birds,
fish and plants disappear forever, a number of rivers and lakes dry up.
In 1986 Belorussian
people faced the most horrible man made ecological disaster. About 18 per cent
of the territory of Belarus was contaminated (были загрязнены). Today we have a great increase in children cancer
and leukemia.
Judging
from the statistics:
In Africa and
Asia about 80% of all energy comes from wood. The burning the fossil fuels and
wood leads to the Greenhouse Effect.
Now, some interesting facts:
1. In central London 40.000 cars every hour use the
roads, causing pollution.
2. Growing
coffee causes deforestation.
3. Every year
around 2 million sea birds die after eating plastic bottles.
4. It costs
around $150 million to clean gum off the UK streets. Chewing gum is illegal in
Singapore.
Taking
everything into consideration, our future looks very sad.
It’s time we
asked ourselves a question:
-
“What
can I do to protect nature”?
There are four solutions to
the environmental problems: FOUR Rs: REDUCE, REUSE, RECYCLE, RESPECT
Everyone can do a little to protect the environment:
a) Plant a tree
in your yard.
b) Conserve
energy.
c) Switch off lights
when you leave a room.
d) Take a shower
instead of a bath.
e) Prefer to
walk, ride the bike.
f) Collect and
use rainwater.
g) We should
remove factories from cities.
t) Reduce ,
recycle our wastes.
We should
realize that we are all responsible (ответственные) for our planet and we must think about future of the
world we live in.
