CONTENT OF THE LESSON:

What is Land Pollution?

Land pollution happens when the ground becomes dirty because of waste like:

1. Open Defecation:

When people use open land as a toilet — this is dangerous and unhealthy.

Effects of Land Pollution:

1. The land becomes dirty and smelly.
2. It causes the spread of diseases from flies, rats, and mosquitoes.
3. It spoils the soil so plants can’t grow well.
4. It can harm animals and people who come in contact with the waste.
