Application of technology led to higher standards of living. But this is not without risks. For technology, if not wisely used, if its evil powers are released, man may well be wiped out of the earth. This is no figment of imagination. The two Word Wars tell us how dangerously close man is to annihilation.
Nobody can forget the events of Hiroshima and Nagasaki.
There are several areas where science and technology can intervene and bring benefits to man. Think of the kaccha roads in the villages or of the busy roads in the metropolitan cities. Both are difficult to use. The busy city roads, corroded and congested, must be broadened enough with provision of footpath on both sides of the roads, with modern facilities of toilets, drinking water etc. Technology that lies behind in sub-ways and over bridges too must be fully harnessed to ease the traffic congestion.
