I’m glad to share some idea about garbage classification with you, which was a hot topic these days all over China. To my understand, we should do whatever we can support it. After all, the earth is home to everyone and it’s our duty to provide a health environment voluntarily. Garbage classification isn’t easy in the beginning, and it’s meaningful. By doing so, it will do many good to the recycling of valuable resources. For our environment and life, we are expecting to learn to sort the rubbish and make it as a habit. Every individual can make the difference and bring a bright future for our planet.
