Passage A

Our Earth is a beautiful planet. It has high mountains, blue seas and green forests. It gives us everything we need: food, water, air and energy. But now the Earth is in great trouble. People catch lots of fish from the sea. As a result, there are fewer and fewer fish. Farmers use dangerous

farm chemicals. These chemicals run into the ground and make clean groundwater less and less. Some factories burn oil and gas to make energy. This makes lots of harmful gases and brings air pollution. What’s more, people cut down trees to build farms. Forests become smaller and smaller. Luckily, many teenagers start to do something to save our home. They join beach clean-up activities, take reusable bags when shopping and tell their friends not to waste things. Small actions can make big changes. We only have one Earth. Let’s take action right now.
