The low level literacy, economic backwardness and over population are some of the important aspects of Third World States Culture. A nation can be called super power largely due to its natural resources. All the branches of science should be involved in promoting the rational use of natural resources environmental protection, its improvement and welfare of human society.

The effluents contain heavy metal such as mercury, lead, copper, arsenic, cadmium, zinc and acids and alkalies. Acids and alkalies destroy micro organisms. Some organic pollutants present in effluent are phenol, naphtha, proteins, cellulose fibres and aromatic compounds. Some of the chemicals are carcinogens. Industrial effluents are most hazardous pollutants both on land and water. Main source of mercury is combustion of coal, smelting of metallic ores battery and paint industries cadmium is released from mines, metal, welding, electroplating and pesticide industries.
I) Light. It provides solar energy for photosynthesis. Maximum light energy is available at equator. It decreases towards poles. In a tree more energy is available to upper leaves than the lower leaves. Their rate of photosynthesis is accordingly higher. (ii) Temperature. On the basis of temperature range, there are four life zones - tropical (hot throughout the year), subtropical (hot during summer and cool during winter), temperate (pleasant summer and cold winter with occasional snowy and arctic or alpine (Snowy throughout except for brief summer).
