What are we doing to our planet?

1. Air pollution

Air pollution has many causes. Factories, cars, trucks, and planes burn fuel and send poinosous gases into the air. These make us sick. Then, in some parts of the planet, large areas of forest are burned every year for farming. The smoke goes into the air, too. We need to use cleaner sources of energy, for example solar energy, wind, energy, and the natural force of the water in big rivers.

2. Global warming

Have you ever been inside a car, parked in the sun? When the windows are closed, it gets hotter and hotter inside the car. The poinosous gases around the Earth are similar to the closed windows in a car. The Earth gets hotter and hotter. This is called global warming. Some scientists think this is changing the climate. In some parts of the Earth it rains a lot; in other parts it doesn’t rain for years. This is really bad for all living things on Earth. We must stop poisoning the air!

3. Tons of garbage

Billions of tons of garbage are produced by humans every year. Soda cans, plastic bottles, and bags are a big problem. They accumulate on land and in rivers, streams, and oceans, and kill many sea animals. We must reduce the amount of plastic and metal we use, reuse what we can, and recycle the rest.
