In the, dark ages, men lived in caves and used to dress themselves with the skin of animals. Their world was full of difficulties and dangers. But time changes and now modern men live in comfortable houses. The science has made their life easy and comfortable but on the other hand it has also created instruments of death that give much power to man.
First, we will consider the positive aspects of science or humanity, Science has invented machines and discovered engineers which are helpful to operate them, Now machines do most of man's work. Computer, motor vehicles, ships and aeroplanes provide leisure to man. Through these inventions the distance has been annihilated. Man has reached the moon and interplanetary travel is now a certainty. Difficult surgical operations have become a routine in the field of medicines. Many diseases like small pox, cholera, polio and plague. are fully controlled. and our lives have become healthier.
Science has made our social life very rich. Cinema, radio and television give relief from sorrows and load of work. The production of crops and production in industries has also increased. Our daily life has been revolutionized, the use of iron, stoves, washing machines and telephone have increased comfort and easiness in our daily life. In other words we say that the progress of science are amazing.
Thus science undultedly has made valuable contribution for the development progress of mankind. Scientific developments have out stripped our moral and spiritual progress. The man has become selfish and cruel. In fact science has been misused by the politicians not by the scientists. we can conclude that if it is in right hands then it serves as a blessing otherwise science can make our lives miserable.
