Question

Read the passage and answer the questions that follow.

Environmental protection and management is deservedly attracting a lot of attention these days. This is a desirable development in the face of the alarming rate of natural resource degradation which greatly hampers their optimal utilization.

When waste waters emanating from municipal sewage, industrial effluent, agriculture and land runoffs, find their way either to ground water reservoirs or other surface water sources, the quality of water deteriorates, rendering it unfit for use. The natural balance is distributed when concentrated discharges of waste water is not controlled. This is because the cleansing forces of nature cannot do their job in proportion to the production of filthy matter.
According to the National Environment Engineering and Reasearch Institute (NEERI), a staggering 70 percent of water available in the country is polluted. According to the Planning Commission “From the Dal lake in the North to the Chaliyar river in the South From Damodar and Hoogly in the East to the Thane Creek in the West, the picture of water pollution is uniformly gloomy. Even our large perennial rivers, like the Ganga, are today are heavily polluted”.
According to one study, all the 14 major rivers of India are highly polluted. Beside the Ganga, these rivers include the Yamuna, Narmada, Godaver i, Krishna and Cauvery. These rivers carry 85 percent of the surface runoff and their drainage basins cover 73 percent of the country. The pollution of the much revered Ganga is due in particular to municipal sewage that accounts for ¾th of its pollution load. Despite India having legislation on water pollution [The Water (Prevention and Control of Pollution) Act, 1974] and various water pollution control boards, rivers have today become synonymous with drains and sewers. Untreated community wastes discharged into water courses from human settlements account for four times as much waste water as industrial effluent. Out of India’s 3,119 towns and cities, only 217 have partial (209) or full (8) sewerage treatment facilities and cover less than a third of the urban population.

Statistics from a report of the Central Board for Prevention and Control of Water Pollution. Statistics from a report of the Central Board for Prevention and Control of Water Pollution reveal that 1,700 of 2,700 water using industries in India are polluting the water around their factories. Only 160 industries have waste water treatment plants. One estimate suggests that the volume of waste water of industrial origin will be comparable to that of domestic sewerage in India by 2000 AD. Dis charges from agricultural fields, which carry fertilizing ingredients of nitrogen, phosphorous and pesticides are expected to be three times as much as domestic sewage. By that date, thermal pollution generated by discharges from thermal power plants will be the largest in volume. Toxic effluents deplete the levels of oxygen in the rivers, endanger all aquatic life an
