Even a few hundred year ago, the condition of man roaming in the world at the mercy of the mighty forces of nature, was miserable, if not pitiable. He had to suffer from the vagaries of weather and the far greater attack of diseases. Life in the pre scientific age was ruled by accident, which was explained as destiny. Science, however, has greatly relieved human sufferings espe­cially this is so in the case of medicine, and surgery. In ancient times a leper was left outside the city walls to live as long as he could on charity and then to die. We read that in the great plague of london 1665 people left their plague stricken relatives to die and ran way to save their own lives. Only the other day the bubonic plague, small­pox and cholera would break out almost every year.

But now a days most diseases yield to treatment and many more are prevented or checked by vaccination, injections of many kinds as also by micro surgery and ultra sonic treatment and transplantation of limbs or organs. Apart from fighting diseases, science has made life much more comfortable with various amenities. Imagine the sufferings of our ancestors who had to walk for days in sun and rain over dusty or muddy roads to reach a distant place.

We need no longer cover in the dark at night nor do we sweat in the heat as our ancestors did. Life is for the people in the western countries more comfortable than it is for us. There are so many labour saving devices to give the tired housewife more leisure.

She can finish her cooking in half an hour her washing takes far less time as if she is getting things done by robots. To the man in offices and factories also, science offers all sorts of pleasant amenities. Conditions in mines once used to be like hell now the suffering of the workers have been much reduced and mitigated. Book production, that used to be a costly process in the last century, is now cheap and plentiful.

The student enjoys facilities for writing and reading in a comfortable library, or for doing experiments in the laboratory, which his forefathers could not dream of. In one year, there may be heavy rains in the another, there may be severe drought. Scientific irrigation brings to the cultivator a ready supply of water: mechanized implements like the bulldozer and tractor help him to plough large tracts of land quickly and efficiently. Greater knowledge of soil chemistry has ensured proper use of manures and fertilizers. Refrigeration has helped long term storage of food and its even distribution throughout the year.

But science is also changing man's outlook on life, and as days go by, its benefits will be more and more enjoyed by the common man and reach the household of the poor. Over the past decade or so, more and more attention is being paid all over the world to man's environment on which human existence depends and the maintenance of which is now increasingly being considered as essential for mankind. By environment is meant those natural things that surround us the essentials to sustain human life, such as the earth's atmo­sphere, healthy air and drinkable water, together with the non essentials that help to make life sustainable, such as wild animals or wild places or human living space. With the passage of time, mankind is realising that preserving the essential ingredients of life and the rich natural diversity of the planet is indeed worthwhile. Thus, protecting and saving the environment involves keeping nature's gifts to mankind as much as possible, and in as good a condition as practicable. Pollution, especially in the industrialised belt, and the ecological crisis are not wholly new or novel, though ecology is a comparatively new science.

The idea behind it, preservation of natural resources is, however, almost as old as man. Now the realisation has dawned on humanity that we have been destroying valuable resources and that there must indeed be a limit to our plans and ambitions for development, expansion and growth. Murder of the environment, which involves senseless poisoning of the earth, air and water, and destruction of forest wealth, may be described as ecocide. Our rivers, including the ganga and the yamuna, are polluted the himalayan ecology is seriously endangered in many ways. The consequences of such continuous and reckless use of trees and other natural resources would be disastrous. There are also the dangers from chemical pollution from radio­active wastes, and other wastes from homes, factories, hospitals and laboratories, and from other foreign matter that keeps entering the atmosphere. It is feared by experts that if the energy of the sun is hindered, if the natural processes of purification and elimination are reversed, and if the reckless destruction and pollution continue, mankind may return to the dreaded ice age.

Therefore, preservation and restoration of nature's balance is vital and efforts are being made for that purpose, at both national and international levels. The first systematic and international effort in this direction was made in 1972 through the un conference on environment, held in stockholm. But by that year barely 10 nations had formulated environment protection programs now the number is above 100. A significant development was the charge brought by the third world that the advanced countries the u.s.a.

And certain other countries of the west were using the pollution problem and its dangers as an excuse for going slow in industrialising the backward and developing regions. Some of the stark facts that are deepening the ecological crisis are: about 12,0 new chemicals are being introduced into the world annually some deserts have been spreading and encroaching at the rate of 30 kilometers every year some oceans are reported to be dying and the earth's protective ozone layer is being broken up by aerosols and supersonic aeroplanes. The economists, therefore, warn that these must be viewed as capital, not as sources of additional income. Following the dawning of the realities and greater knowledge of the disaster looming ahead, there is better awareness of the need for environmental education, which millions of educated people have begun to regard as a matter of life and death. The developed and advanced countries may even be said to be exporting their pollution problems to the third world by decentralising their production processes and establishing factories in other parts of the world.
