Science Boon or Bane

Gone is the age of steam. We are now in the age of hydrogen bombs and electricity. The most fantastic dreams of H. G. Wells in his novel Dream have come true. Thus, in this space age, where the wonders of science excel the wonders of nature, science affects our day-to-day life. Science has surpassed the old miracles of mythology and yesterday's faith has proved to be today's superstition in the crucibles of science. Science is a wonderful gift presented to humans. With science, we can create a small matchstick to a huge rocket. Science answers to many of our  questions.Everything around us is just because of science. Internet has given undreamed access to learners. Also science has always helped us to come out from the jaws of death. Nowadays medical techonology is so improved that we can cure illness in the finest part of the body without having any physical contact with it. Their is no field where science has not developed and helped us to make our life's easier. Even agriculture is now depend on science . Robots now do man's chores. Mobile phones, computers have allowed us to reach in  any part the world at any time.Where we need 100's of pages to write a data , it can be now saved in a small chip which we can carry everywhere. Because of all these things science is like a boon to mankind. But it is humans irrational thoughts turn the gifts of science into banes. It is said that science is a good servant but a bad master. When we regenerate energy from natural resources like wind, sun, water and other non biodegradable substances we feel proud but when the consequences lie on ozone layer depletion, radioactive radiation make us afraid.I think it's truly said that good and evil are two sides of a same coin as on one side it has made our life comfortable and easy and also we cannot ignore the other side that science made factories which led to pollution and made phones which causes our eyes irritations and made transport which led to air pollution science made electricity which leads to wastage of coals. So at first we need to restrict our greedy thoughts which may lead to destruction of our planet. If we are able to do that then science will remain as a boon always for mankind.
