     We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans,

killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers

have been unsuccessfully looking for a solution.

     The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has

discovered a way to make plastic bags degrade (降解) in as few as 3 months. a finding that won him first

prize at the Canada-Wide Science Fair, a $ 10,000 prize, a $ 20,000 scholarship, and a chance to revolutionize

a major environmental issue.

     Burd's strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微

生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster

than under normal conditions.

     With this goal in mind, he grounded plastic bags into a powder and concocted (调制) a solution of

household chemicals, yeast (酵母) and tap water to encourage microbes growth. Then he added the plastic

powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture

on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed

(暴露) to the live bacteria was 17% lighter than the control after six weeks.

     The inputs are cheap, maintaining the required temperature takes little energy because microbes produce

heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

     "Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags

falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these

plastic bags. The answer: not much. So I decided to do something myself." said Daniel Burd.
