Caterpillars（毛毛虫）are cute. They star in children's books. They turn into pretty butterflies. And now it turns out they may hold the key to solving plastic pollution.

Like many great findings and inventions, the discovery of a caterpillar that eats plastic was made accidentally. Bertocchini, a biologist in Madrid, was cleaning her hobby beehives(蜂箱）and used a plastic shopping bag to collect the caterpillars which eat wax(蜂蜡）. When she looked at the bag later, she was surprised to see it was full of holes. She decided to look into this plastic-eating wonders of caterpillars with her team.

They offered a plastic bag from a UK supermarket to a group of 100 wax-eating caterpillars. They began creating holes after 40 minutes; 12 hours later, they had reduced the mass of the bag by 92mg. While there have been other creatures that eat plastics, none of them have been able to do so better than these caterpillars.

"This discovery could be an important tool for helping to cut down the problem of plastic waste and save our oceans and rivers," Bertocchini said. "The caterpillar will be the starting point. Before using this finding in a practical way to solve plastic problems, we need to understand the chemical secrets behind the natural degradation(降解）of plastic. Something in the caterpillar一as well as the caterpillar itself—might play a role".

Everyone expects to live a relaxing life after retirement（退休）, isn't it? However, this is not the case for Mr. Bai Fangli. In 1987, at the age of 74, he decided to continue working as a pedicab（三轮车）driver. But he didn’t work to make money for himself, but for the poor children who are not able to afford education. Once he started, he never stopped.

Life as a pedicab driver was not easy, but Bai kept working hard. Every day he went out in the early morning and wouldn't return until darkness. He made 20 to 30 yuan each day. After returning home, he put his money in a lunch box carefully. In almost twenty years Bai hardly bought any clothes or a pair of shoes for himself. He gave away all the money he made from his job. By the time he was 88, he had given away more than 350,000 yuan and helped more than 300 poor students return to school.

One winter in 2001, he drove his pedicab to Tianjin YaoHua Middle School and handed 500 yuan to a teacher. He said, “I cannot work anymore, and this is the last money I can give to help others.” 4 years later, he got lung cancer and died when he was 92.
