20、vered a way to make plastic bags degrade (分解) 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.Burds strategy was simple: Since plastic does eventually degrade, it

21、 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 ground plastic bags into a powder and concocted (调制) a solution of household chemicals, yeast (酵母) and

22、 tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months.

23、 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 ope
