Protect the Earth
The Earth is a beautiful place.
There are forests and rivers, mountains and fields. Some places are very hot, and some are very cold.
There are many different plants. Some are large. Some are small. All plants need light and water. There are different animals on Earth too. Some live on the land. Some fly in the sky. Some live under the water.
There are also many people like you and me on Earth. The Earth provides us with air, water and food. It is our home.
Today, there is a lot of pollution. We burn things to make energy. This pollutes the air. We put our rubbish into the sea and under the ground. This pollutes the Earth and kills animals and plants.
We must stop doing these things. It is important for us to protect the Earth for our future.
