I need essay on pollution for class 4th​

Answer 1

Answer:yes

Explanation:

Pollution is the root cause for the deteriorating environments globally. There are four main types of pollution: Water pollution, ground pollution, air pollution and sound pollution. Let us first discuss about water pollution. It is caused by industrial waste and household waste. All manufacturing companies use chemicals in their production processes. After production, there will be waste water after cleaning the machines. That water is left into sewages and these sewages connect to rivers and oceans thereby contaminating the water. Due to this, large number of fish die every year and some species became extinct by now.

Next, air pollution and ground pollution.

All the rubbish in your home is buried under the ground and only some parts are recycled. The buried rubbish will reduce lands fertility. It also emits carbon emissions which are harmful gases to live with. Also, vehicles on the roads let out carbon monoxide from their exhaust pipes and this will reduce oxygen levels thereby making it difficult for you to breathe.

Finally sound pollution.

This is caused by loud noises from speakers, machines, horns and aeroplanes. The governments are trying their best to avoid all sorts of pollution and finally succeeded in preventing it from spreading and to reduce global warming.
