Migration is also major cause of pollution. Every day a large number of people are coming to towns and cities in search of jobs and employment. Towns and cities are being expanded. Forests are being cleared off. These spaces are being utilised for setting up of factories, and making buildings and houses. But there is a wide gap between demand and supply. It has led to spread of slums in cities and towns. The slums do not have basic amenities for the inmates.
These people live in unhygienic conditions. They go for natural call in the open. This contributes to the pollution problem. Environmental pollution is contributing to global warming.
It has made this problem all the more complex. Government is taking efforts to contain this problem. As a measure government is gradually promoting CNG-run vehicles.
They produce comparatively less pollution. In most of the states lead-free petrol is being provided. In big cities, vehicles are regularly being checked for pollution.
Factories and small industries are being shifted to some remote areas. But we have failed to get desired result. As an aware citizen it is our responsibility to take step to keep environment clean. Media and NGOs have prominent role to play. They should create awareness. Only then we will be able to check this menace.
The situation calls for an integrated approach.
