Pollution

Pollution: Keeping Our Environment Clean!

Pollution means making our environment (the air we breathe, the water we drink, and the land we live on) dirty with harmful things. When our environment gets dirty, it becomes unsafe for living things, including us!

Key Points

There are three main types of pollution we need to know:

1. Air Pollution: This happens when harmful gases, smoke, and dust fill the air.
2. Water Pollution: This occurs when dirty and harmful substances like waste, chemicals, and plastics get into rivers, lakes, and oceans.
3. Land Pollution: This is when waste, rubbish, and harmful chemicals are dumped on the land, making the soil unhealthy.

What Causes Pollution? Many things cause pollution, mostly from human activities. Some common causes are:

• Throwing rubbish anywhere (indiscriminate dumping).
• Smoke from cars, buses, and factories.
• Burning tires, bushes, or waste.
• Pouring dirty water and chemicals into rivers.
• Oil spills from ships.
• Open defecation.

Practical Activity

Think about the litter you sometimes see on your street or in your school compound. That's land pollution! At home, you can help by always putting your waste in the bin and sorting plastics for recycling if your community has a recycling program.
