1. Air pollution Polluted air can be dangerous, even without visible pollutants. It can burn people's eyes and make breathing difficult. It may also increase the risk of lung cancer. 2. Water pollution Polluted water is dangerous for drinking and swimming. Some people drink contaminated water, being exposed to harmful chemicals that can make them sick for years to come. Others consume bacteria and other tiny aquatic organisms that cause disease. The United Nations estimates that 4,000 children die every day from drinking dirty water. 3. Soil pollution Many of the same pollutants as foul water also damage the soil. Mining sometimes exposes the soil to dangerous chemicals.

Garbage is another form of soil pollution. Around the world, paper, cans, glass jars, plastic products, old cars, and appliances have taken over the landscape. Waste makes it difficult for plants and other producers in the food web to make nutrients. Animals can die if they ingest plastic by mistake.
