| Pollution |
With the growth of population the atmosphere has become polluted. Industries have greatly added to this pollution. The air around us has become dirty. The content of poisonous gases has increased.
Towns and cities expanded rapidly. More-and-more space is being used for building houses and factories. More-and-more people coming to the towns and cities. The houses are in short-supply. So they live in open or in huts. They go for nature call in the open. This causes pollution.
There is a lot of traffic, buses, cars, scooters, motor cycles are multiplying. They use diesel and petrol. Their smoke pollutes the air. There are big and small factories using coal, sending poisonous gases into the air.
There is also water pollution. There are cities on the banks of the river. Their sewerage falls in the rivers. Thus water gets polluted.
We have done away with the forests. This has caused pollution. We should grow more trees to control pollution.
