This modern age is called the age of science. Science has brought great changes in the life of man. It converted much impossibility. Science gave electricity, electronics, telephones, aeroplanes and several other things for pleasure and comfort of man. It has minimized suffering and increased happiness of man.

Science is also responsible for human misery in many ways. Science through industrialization and mechanization brought urbanization, unemployment and unequal division of monetary benefits. Rich have grown richer and poor became poor. The mankind has been divided into haves and have-nots or rich and poor. The poor toil more and rich enjoy more. This unequal balance of humanity is due to science.

Science is responsible for wars and deadly modem weapons like long range remote control and radar guided missiles, poisonous gases, biological weapons, atom bomb, hydrogen and neutron bombs that can destroy the whole of the world population and the world in few seconds only. Such weapons are amassed by superpowers in greater number. The recent star war projects developed by America to prove its superiority in a deadly menace to the world peace. When the different nations in the world stall their mad frenzy of arm race is not known. Today the whole of the mankind is sitting on key of gun powder to be blown away any moment.

The facilities given by science are being misused by man for example atomic energy has infinite potential both for destructive and constructive purposes. On the one hand atomic energy can be successfully used for converting barren deserts in to fertile lands. But on the other hand it can be used for total annihilation of humanity. It is thus the application of scientific mind either to peace or war. Percent day modern super fast vehicles are used for wars rather than peace. Because of unnecessary arms race, the nuclear explosion conducted are polluting atmosphere, the world is threatened with radiation hazard. The dreaded killer diseases like cancer etc are spreading due to nuclear and other chemical pollutions.

Science has affected our social life very badly. Man became materialistic and his spiritual feelings are drying up along with the progress in science. Modern science is leading men towards material aggrandizement at the same time depriving him morally and intellectually. Science has made man selfish, greedy and jealous. Man became more dependent on science than on his own self. Science, the servant of man is controlling master that master controlling it. It made man to leave spirit of friendship and fellow feelings. Science has robbed away the peace of mind. It has no doubt given physical comfort to man, at the same time it made him a morel wreck, timid and a weakling. Man has become incapable and important without the scientific appliances around him to lead him normal life.

The misuse of scientific knowledge is the cause of our troubles and unhappiness. Nations are indulged in war due to greed and selfishness. Wars and weapons rob away riches of mankind. Science can provide food, shelter, clothing and many other comforts to the whole of the mankind on earth. However science is a double edged weapon which can be used to give both pleasure and pain. The use of it depends on man. It is not the fault of science, if it is used for wars and destruction instead of peace and prosperity.
