Pollution is when harmful things get into air,water,or land. It can make our planet sick. Imagine (设想) if your favourite park was full of trash. You wouldn't like to play there,right? Factories can let out smoke in the air. Cars can too. These smoke can make it hard for us to breathe (呼吸). Trash in water can hurt fish and animals. The water will become unsafe for us. But we can help to stop pollution! Turning off lights saves energy. Riding bikes instead of using cars keeps the air clean. Recycling means less trash in the park and in the water. Let's help keep our Earth clean and healthy. We can all be Earth heroes!
