These days we notice the rubbish bins (垃圾箱) are in different colors on the street. The bins are in different colors because they can help people sort the waste. When we throw away rubbish, we should know which bin we should choose first.
Some of us might find it hard to choose the correct bin. However, it's actually quite important to know how to sort your rubbish. If we don't know how to sort rubbish, it can be harder to save energy and protect the environment. If we don't sort our rubbish, cleaners will bury (埋) all the rubbish together. It takes up large areas of ground that can be used for planting trees.
Shanghai is the first city to put rubbish-sorting into practice in China. Shanghai government asks the people to sort rubbish into four kinds. They are wet, recyclable, harmful and dry.
Wet rubbish is the rubbish that people produce after they eat or drink. Paper, metal, glass and other things that can be reused are called recyclable rubbish. Harmful rubbish includes things like medicine, batteries (电池) and so on. Finally, any rubbish that is not wet, recyclable or harmful will go in the dry rubbish bin.
Many Chinese big cities plan to put rubbish-sorting (垃圾分类) into practice. Now that you know this, perhaps you can take part in sorting the rubbish.
