When throwing away rubbish, do you know which bin it should go in? Have you ever noticed the differently-colored rubbish bins on the street? Some of you might not be able to answer the questions. However, it's actually quite important to know how to sort your rubbish. Not knowing how to sort rubbish can make it harder to save energy and protect the environment. If you don't sort your rubbish, all of it will be buried (埋) together. It can take up large areas of ground that could have been used for planting trees. Shanghai is the first city to put rubbish-sorting into practice in China.
Shanghai government has asked all the people who live there to sort rubbish into four groups: wet, recyclable (可回收的), harmful and dry. "Wet" rubbish is also known as "household" rubbish. It is what people produce every day after they eat or drink. "It is the thing you don't want but pigs can eat", Guangzhou Daily explained. Paper, metal, glass and other things that can be reused are recyclable rubbish.
Harmful rubbish includes things like medicine, batteries and so on. Finally, any rubbish that is not wet, recyclable or harmful will go in the dry rubbish bin. Many other Chinese cities, including Changsha, plan to use this method to sort their rubbish. Now that you know this, perhaps you can do your part in protecting the environment.
