Protect the Earth
The Earth is a beautiful place. There are a lot of high mountains, blue seas, and beautiful rivers. The Earth provides us with air, water and food.
This beautiful planet is our only home. However, we are harming the Earth in many ways. For example, factories put dirty water into lakes and rivers. It causes water pollution. Besides, people use too much plastic and throw rubbish everywhere. As a result, lots of sea animals are dying because of plastic pollution.

Post-writing
What’s more, some people cut down many trees to build farms. So there is less and less forest land.
We only have one Earth, so we have to protect it. First, factories should stop polluting rivers and lakes. Second we bring our own shopping bags to the supermarket and sort rubbish in the right way before throwing rubbish into the trash can. Finally, it’s important for us to plant more trees to make our Earth more beautiful.
Let’s start small and protect our Earth!
