CONTENT OF THE LESSON  

LESSON 1 – INTRODUCTION 

Pollution is the presence in or introduction into the environment of a something which has harmful or poisonous effects.

MEANING OF POLLUTION 

Pollution is anything that makes our water, land, air and environment dirty and unsafe to use.

For example, a heap of rubbish is a type of pollution. A dead animal lying on the road causes pollution.

 

This leads to the contamination of the air, water, or soil.

These harmful substances introduced into the environment are called pollutants.

The types of pollution we have are

1. Land pollution

2. Water water pollution

3. Air pollution

3. Noise pollution

 

LESSON 2 – MEANING OF WATER POLLUTION

Water pollution is anything that makes our water dirty and unsafe for drinking and general uses.

Polluted water is unsafe for humans, animals and plants.

 

HUMAN ACTIVITIES THAT POLLUTED THE WATER

Pollution can happen through human activities like –

  • dumping human waste in the water.
  • leaving dead farm animals near water.
  • washing clothes with detergent or soap in a river or stream.
  • emptying industrial waste into the rivers/streams, etc.
  • erosion carries harmful substances like pesticides and fertilizer into rivers/streams.

Polluted water carried deadly bacteria, such as those responsible for,

1. diarrhea

2. cholera

3. dysentery

4. typhoid

5. death

 

PREVENTION OF WATER POLLUTION

1. Avoid dumping human waste in the water.

2. Bury or burn dead farm animals immediately.

3. Don’t wash clothes with detergent or soap in a river or stream.

4. Farm chemicals like Fertilizer, insecticide and pesticides should be apply correctly.

5. Industrial should dispose their waste properly.
