Saving Our Earth
Our earth is facing many serious problems. One of them is pollution. Factories pour waste water into rivers and lakes, making the water dirty. People throw rubbish everywhere, and the land is full of garbage.
Deforestation is also a big problem. Many trees are cut down, so some animals lose their homes. And this also leads to climate change.
To save the earth, we need to take action. We should sort garbage and recycle useful things. We can reduce the use of cars and choose to ride bikes or walk. Planting more trees is also a good way to make the earth greener.
Everyone should play a part in saving the earth. Let's start from small things and make our planet better.
