प्रश्न
The disposal of urban waste has become a serious concern for the local authorities. Analyze the statement with suitable examples.
उत्तर
The problem of overcrowded, congested and insufficient infrastructure of urban areas results in accumulation of huge urban waste. There are two sources of urban waste. Household or domestic sources and industrial or commercial sources. The mismanagement of urban waste disposal is a serious problem in big cities.
Tons of waste come out daily in metropolitan cities and are burnt. The smoke released from the waste pollutes the air. Lack of sewers or other means to dispose of human excretes safely and the inadequacy of garbage collection sources adds to water pollution.
The concentration of industrial units in and around urban centres gives rise to a series of environmental problems.
Dumping of industrial waste into rivers is the major cause of water pollution. The solid waste generation continues to increase in both absolute and per capita in cities.
This improper disposal of solid waste attracts rodents and flies which spread diseases. The thermal plants release a lot of smoke and ash in the air. For example, a plant producing 500mw electricity releases 2000 tons of ash which is difficult to manage.
