Science:Friend or Foe

Introduction:

We are living in a scientific age. Every country is trying to make as much scientific progress as possible. Science has been used for many good purposes. For example, we can use electricity and different kinds of gases because of scientific progress. All kinds of machines that we use in home and in factories and at other places are the result of science.
Good uses of science:
There are many scientific inventions we use now. For example, the radio, television, telephone, mobile phone, computer, laptop, internet, motor car, railway engine and aircraft are some of the most important scientific inventions. We can hear the voice of persons speaking thousands of miles away on radio. We can talk to others anywhere in the country and outside the country on mobile phone and telephone. The motor car, railway engine and airliner have made travelling very quick and easy. Science and scientists have made our life what it is. There has been tremendous development in health matters. We have many new medicines for our diseases. There are injections which cure some of our diseases very quickly. Surgery has also made great progress. Operations of the heart and brain are possible now. All this medical and surgical progress is due to modern science. In agriculture, we have new machines like tractors which help us in sowing and reaping our crops easily and quickly. There are very useful salts and fertilizers which make our lands very fertile. There are hybridized seeds that increase the production of crops. Insecticide, pesticide and other sprays crops are indebted to science. The production of our food increases much due to the use of science. Hence, science has benefited society much.

Bad uses of science:
science has also been used for bad purposes. It has been use to harm society in a number of ways. Scientists have prepared destructive weapons of war. For example, machine-guns and huge guns can kill thousands of persons in a few minutes. There are tanks and fast-moving vehicles which can bring great destruction to human beings. The bomber planes move very fast and drop bombs on city and village during war. All this means that scientists have made war very destructive. The worst use of science was made in the 20th century when the atom bomb was made. This bomb was dropped on two cities of Japan, Hiroshima and Nagasaki in the Second World War. The two cities were completely destroyed and thousands of human beings were killed. Afterwards scientists prepared the hydrogen bomb which is even more dangerous. Politicians in different countries ask scientists to prepare more horrible weapons and bombs. Such practices are to stigmatize the uses of science.

Conclusion:
Scientists should try to invent those things only which benefit human beings anywhere in the world. Science has taught us how to do our work exactly with the help of machines. We use scientific methods without prejudice for others. So science teaches us to live without prejudice in society. Space travel has become possible with the help of science. Man has visited the moon. He may be visiting other planets. So science has made impossible things quite possible. Let all the countries of the world decide to live in peace. The scientists of different countries should use science for the progress of mankind. They should pledge to use science in sensible way.
