continued--As is well known that the industrialization has brought many new and novel nature occurring products like coal, petroleum, gases etc which lay hidden underneath the earth for thousands of years and the consumption of which have started producing gases like carbon monoxide, carbon dioxide and others adding to the gas composition of the atmosphere. The new gas composition in the atmosphere is further mixed with the different exhaust gases from the industries and as a result the atmospheric temperature has been rising ( the process of heating is not the subject matter here) much to the detriment of atmospheric quality to the health of the creatures who are rather helpless in the matter. While human efforts are there at the national and international level to combat the green house effect(the heating of the atmosphere )being out of the scope of this essay, the fact remains that the humans have been subject to the toxicity of the human created gases, which if the human system fails to adjust may bring in disaster to the human race.

Water--The second mandatory requirement for survival of the humans is clean, pure,sweet and potable water which the humans have been using from rains, springs, rivers,lakes, pools, wells etc for thousands of years. There was not much problem t o get access to the drinking water but with increase in population, growth of satellite townships due to industrialization water scarcity has started surfacing and over and above the huge consumption of water in big industries has complicated the situation in a number of ways. The effluent of the small and big industries contain many chemical compounds which are injurious not only to human health but even also  to the crops which the humans consume. In big town, cities and mega cities municipal bodies have to make elaborate arrangement for storage of water from different sources,and do take all necessary steps to make it potable. In many countries the supply is not adequate and the quality is far from criticism . Surprisingly even the tubewells in some areas yield high percentage of iron, arsenic    (to be continued )
