Pollution Explained

Key Concepts

• Air Pollution
• Water Pollution
• Land Pollution

Air Pollution

Air pollution is the contamination of the air by harmful substances, such as smoke, chemicals, and dust. These pollutants can come from factories, vehicles, and burning fossil fuels. Air pollution can cause health problems like asthma and lung diseases, and it also contributes to climate change.

Imagine air pollution as a thick, dirty fog that covers the sky. This fog makes it hard to breathe and see clearly, just like air pollution makes it hard for people and animals to breathe clean air.

Water Pollution

Water pollution is the contamination of water bodies like rivers, lakes, and oceans by harmful substances, such as chemicals, sewage, and plastic waste. These pollutants can harm aquatic life, make water unsafe for drinking, and damage ecosystems. Water pollution often comes from industrial waste, agricultural runoff, and improper waste disposal.

Think of water pollution as a big, murky puddle. This puddle is filled with dirt and garbage, making it unsafe for animals to drink and play in, just like water pollution makes water unsafe for fish and other creatures.

Land Pollution

Land pollution is the contamination of the land by harmful substances, such as plastic, chemicals, and garbage. These pollutants can harm plants, animals, and people, and they can also make the land less fertile for growing crops. Land pollution often comes from improper waste disposal, industrial activities, and agricultural practices.

Picture land pollution as a messy playground. This playground is filled with trash and broken toys, making it unsafe and unpleasant for children to play in, just like land pollution makes the land unsafe and unhealthy for plants and animals.
