FIFTEEN YEAR-OLD  Liu Xuyang said he has more than 30 pairs of shoes．But some are old．He doesn’t want them any more．

Where should these old shoes go? To the garbage or to be recycled?

This is bow Liu began to care about old shoes．He shared his thoughts with his classmates at Beijing No. 35 Middle School，Luo Hao and Yang Mengwei．The three then decided to do some research．They found out that old shoes can pollute the environment if not recycled properly．Earlier this month，their research paper won second prize in the Beijing Youth Science and Invention Competition．
