Improper treatment <strong>of</strong> sewage leads to the accumulation <strong>of</strong> solids, such as biomass sludge. These<br />

solid wastes overflow through the sewage, making the entire area look dirty. Burning <strong>of</strong> solid<br />

fuels leads to the formation <strong>of</strong> ashes, which is yet another cause <strong>of</strong> l<strong>and</strong> pollution. Although<br />

domestic <strong>and</strong> industrial wastes are collected <strong>and</strong> recycled or burnt in incinerators, a large amount<br />

<strong>of</strong> rubbish is left untreated. These are then dumped into grounds, leading to l<strong>and</strong> pollution.<br />

Garbage dumped by people makes the streets unhealthy, unfit <strong>and</strong> dirty to reside in. The waste<br />

matter usually consists <strong>of</strong> leftover food, fruit <strong>and</strong> vegetable peels <strong>and</strong> other non-decomposable<br />

solid materials such as glass, cloth, plastic, wood, paper etc. . 28<br />

Water pollution<br />

Water pollution is the result <strong>of</strong> human activities. Waste water is problem that has been there since<br />

the beginning <strong>of</strong> industrial era. Waste water are different chemicals discharged mainly by<br />

factories, <strong>of</strong> which much gets pumped untreated into rivers, oceans, <strong>and</strong> other water bodies. 29 The<br />

eco-system <strong>of</strong> rivers, streams, lakes, seas <strong>and</strong> oceans is also getting deteriorated due to the<br />

contamination <strong>of</strong> water, through various sources. Dumping <strong>of</strong> industrial wastes, containing heavy<br />

metals, harmful chemicals, by-products, organic toxins <strong>and</strong> oils, into the nearby source <strong>of</strong> water<br />

is one <strong>of</strong> the visible causes <strong>of</strong> water pollution. Another cause for the contamination <strong>of</strong> water is the<br />

improper disposal <strong>of</strong> human <strong>and</strong> animal wastes. Effluents from factories, refineries, injection<br />

wells <strong>and</strong> sewage treatment plants are dumped into urban water supplies, leading to water<br />

pollution. 30<br />
