Preventing Different Types of Pollutions
Water pollution can be prevented by:
* Treating domestic sewage and industrial waste in treatment plants before releasing them into water bodies.
* Prohibiting activities like washing and bathing in lakes, canals and rivers.
Soil pollution can be prevented by:
* Using organic manure
* Recycling waste paper, glass, plastic and metals
Trees help to reduce water, soil, air and sound pollution. Hence, plantation activities must be encouraged.
Air pollution can be reduced by using:
* Electrostatic precipitators and scrubbers in factories.
* Solar coolers, bio – gas and smokeless chulhas at homes.
* CNG, catalytic converters, unleaded petrol and bio – fuel in vehicles.
* Public transport in big towns and cities
* Using televisions and tape recorders at low volume and minimal honking while driving can prevent sound pollution.
