“Science-A Boon or Curse for Mankind”

INTRODUCTION:
We are in the age of science and technology. Everything in the universe has its uses and abuses. The same applies to science. Science has revolutionized the human existence. It has made man's life happier and more comfortable. Man cannot live without the aid of science. Science has so much engulfed our lives that nothing can take place in our day to day work without the help of science. There is the other side of the coin also. That science gave birth to destructive weapons like dynamite, guns, rifles, rockets, atom bombs, hydrogen bombs only to destroy people.
SCIENCE IN OLD CIVILIZATION:
In our olden civilization also there had some science in their daily life. The people used wind mills to lift water from the wells, they used turmeric as it is a good antibiotic , the people guessed the future perfectly without any knowledge , the tamil poets before 1100 years who said that world is formed through the burst of sun is proven by scientists in 16th century. the big temple which is built in 10th century is still a matter of discussion for the modern engineers who baffeled that how would the workers would taken the stone of 90tonnes to the top of the temple. The invention of them simple wheel has resulted in our modern industrialization.
Science in agriculture field
Science is a help in the agriculture field too. The food production levels and quality have improved by multiple factors. Soil analysis, hybrid varieties of crops giving higher yield, fertilizers, pesticides, advanced tools and machinery, irrigation equipments, etc. have increased the production of crops.Electricity is one of the greatest wonders of modern science. The growth of fast modes of transport and communication has changed the world into global village. In the field of agriculture, science has helped in increasing the crop production and improving quality.

MAN VS NATURE
The discovery and development of a large number of powerful energy sources-coal, petroleum, natural gas, electricity etc. have enabled humanity to conquer the barriers of nature. All this has facilitated the growth of fast modes of transport and communication, which in turn has changed the world into a global village. Science has given man the means of traveling-cars, trains, aero-planes, ships etc. man has even traveled to the moon. Science has posed a threat to the very existence of mankind with weapons-nuclear, biological, atomic, chemical etc
USE OF ELECTRICITY:
Electricity, as a source of energy, has revolutionized the world. Medical science is so much advanced that the average life of an Indian has risen to 62 years from 35 years. Science has contributed to the success of our green revolution and now we have enough food for all. We have enough clothing and better shelter too. All this is possible, because of science. Radios, T.C s and cinemas which entertain us are the products of science. So a common man has to conclude that science is a boon to mankind.
USE OF SCIENCE IN FIELD OF MEDICINE:
Open heart surgeries, organ transplants etc. have all become possible. A number of killer diseases are now curable. Diseases such as smallpox, polio, plague, malaria etc. have now almost been eradicated. Hidden diseases in the body can be diagnosed easily with the help of X-rays. Scientists have succeeded in cloning animals. The methods of diagnosis, prevention and treatment have developed with a rapid speed. As a result of this much progress in medical science, man finds himself more safe, secure and his average age has lengthened.
HIROSHIMA AND NAKASAKHI ATTACK:
Sir Alfred Nobel experimented with dynamite to clear huge mountains to turn it into productive land. but modern man is using it to kill his fellow human beings and destroy nature. The destructive potential of atomic energy was witnessed in August 1945, when the United States dropped atom booms on the Japanese cities of Hiroshima and Nagasaki. Those who survived the nuclear bombing suffered from its aftermath. It is a horrible fact that much of the national income of even a developing country is spent on acquiring latest weapons, bombs and missiles.

NEGATIVES OF BIOTECHNOLOGY:
Biotechnology is a great boon for fighting the diseases. But along with medicines lethal biological weapons have also been developed. Germs are deliberately released into the air to spread diseases. Anthrax envelopes are used for spreading terrorism.The negative effects of the excessive use of fertilizers and pesticides, used to increase yield, are now evident. soil salinity has increased. Traces of DDT are found in plants.

CONCLUSION:
Science has two faces-good and bad. It depends on us which face we want to see. If we use the gifts of science in positive direction with positive intention then it will provide us with sweet results but if we use it in the wrong way the results will definitely be bitter. To save ourselves and the world as a whole from destruction, we should follow the right way to use the gifts of science so that it appears as a blessing and not as a curse.
