The scientists believe that nearness to the sun by a few thousand kilometres would have raised earth’s temperatures to such a degree that no life could survive. Similarly, if our earth had been away from the sun by a few thousand kilometres, this would have created freezing temperatures.

We get necessary oxygen from the air we breathe. As breathing is our most pressing and regular necessity each moment, air has been provided on the earth’s closer-most atmosphere in great abundance. We just have to keep breathing; the air is always there for us.
But we are vitiating this atmosphere with our activities. Millions of big and small factories have been set up across the globe. The smoke coming out of the chmineys of these factories is causing air pollution. The number of vehicles is increasing day by day. The smoke...
