Answer :
Man's greatest invention and the only greatest cause of destruction was Science. If man would not have invented science the world would have been a happier place to live in and for the mis-users of science.
Science, it was not known to people till the 10th Century. The people used to look at everything as an act of God. But Science has given the real answer to each and everyone and nowadays no one even thinks to know about anything without the auspicious touch of science. Science is now even a poor man's work, for example, a motor used to distribute water evenly to each farmer's fields, similarly the fertilizers which are harmful but still used. Earlier farmers used to put manure to their crops but now they put on fertilizers which are very harmful. Now, by this 21st Century, everything we see around us is an invention of science. Science has even played a major role in shaping the lives of all. Due to science we are able to live lavishly and have a lot of entertainment. It is due to science that we exist on this Earth. Science is the basic need of our daily life. Nowadays it seems that science has bestowed a lot on us but we keep on forgetting that the nature has instilled a lot of facilities. We neglect them and keep on our way with science. So I conclude with the thought that in the future generation there will be everything that will depend on science. We would be so dependable on them that they would almost be into their trap and without anyone of us noticing that.
