The mode of living of the primitive people and the mode of living today, are notÂ same. The primitive people did not know how to live comfortably like modern people because they had no knowledge about science. If we carefully study the progress of human civilization,Â we shall find that the progress has been made due to science. In different spheres of our lives, science has made wonderful progress in areas like food, shelter, clothing, power, materials,Â transportation, communication and health.
Primitive people did not knowÂ how to grow crops, make food, make houses, clothes, use powerÂ without using animals, make different things like planes, buses, cars etc. In ancient timesÂ they ate raw meat, used leaves as clothes, used animals as a means of transport. But now science has changed it all and developed all these spheres.
Thus, we see what science hasÂ doneÂ for the comfort of modern men.Â But in spite of it all these, men are not alwaysÂ happy.Â There has been war among the nations, and science has hel-ped menÂ to make weapons to destroy human lives and properties. So,Â science is not always a blessing. It is sometimes a curse as well.
But if we deeply think over the matter, we shall find that men themselves are to blame for making their lives unhappy. Science itself is neither good nor bad. SoÂ men must change their outlook of lives. If all men get accustomed to think that they are all brothers, there will be no war. They will live in peace and happiness. The condition of the backward nations of the world can also be improved with the help of science. Thus,Â science can add happiness to mankind.
