There are many ways through which pollution occurs and there are many kinds of it also. The few ways to contro it are:
encourage plantation as greenery are the lungs of the city, relocating the industrial area from the city to a distant place and properly disposal of the industrial wastes,banning the use of plastic bags, banning older commercial vehicles to run on the road as they produce much more harmful smoke than the new vehicles with hybrid engines etc.
Pollution cannot be controlled that easily as people are addicted to the facilities. First cause of pollution is petrol. But without petrol no vehicle can move.So petrol is necessary. So at least while using vehicle we need to stop when we are not going any where, I mean while standing at signals , try to stop the vehicle. At least 2% of the pollution can be reduced.
second cause is through factories. the smoke and the waste from the industries and factories.So government should not give them permission to establish their factories and industries in the city or town.
Third cause is usage of politen covers should be stopped. If the production of the politen cover stops then usage of them will be automatically stops. But people always says us to stop using but they wont stop production.
Pollution in food items. The shop keeper or the farmer ripe the fruits by using some chemicals before they get ripen.
Pollution in soft drinks, for profit and store for more time they started using pests in soft drinks.
Pollution should be controlled in every possible way and I too believe like other honorable members of this site that education could play a vital role to get any success in it....
