Greenhouse
effect signifies gradual warming of the earth‘s atmosphere. It is thought to be
caused by increased carbon dioxide in the air. The scientists are very much
concerned about this natural phenomenon. In recent years there have been many
alarming reports that the world‘s climate is undergoing a significant change.
All these reports provide strong evidence that world temperatures are increasing
day by day. This increase is known as global warming caused by increased amount
of carbon dioxide around the earth. Most climatologists believe that the
‗greenhouse effect‘ is the most likely cause of this global warming.
Climatologists predict that by midway through the next century temperatures may
have risen by as much as 40 C. This could catastrophically reduce mankind‘s
ability to grow food, destroy or severely damage wildlife and wilderness, raise
sea levels and thereby flood coastal areas and farmland. As a result of the
rise of the sea level, the lower southern part of the country may one day go
under water. Scientists are now taking steps to isolate and destroy radioactive
elements which are really dangerous for mankind. In fact, its damaging effect
is so extensive that it is one of the most widely discussed topics nowadays.
Sensing danger, the United Nations Environmental Programme is sponsoring 5th
June of every year as the World Environmental Day to evolve fruitful
possibilities. Seminars are being regularly held all over the world to make the
people conscious of the impending danger to mankind. We must follow the guidelines
to create a better environment and save life on this beautiful planet.
