When he was nine years old，American boy Milo Cress had a question：How many plastic（塑料） straws （吸管） do Americans use every day？
   He quickly learned there wasn't a simple answer.The boy tried to work it out himself.Through lots of research，Cress found out that Americans use about 500 million straws every day.In hopes of reducing（減少；縮減） plastic waste，he founded（創(chuàng)建） the Be Straw Free project in 2011.
   Cress started the project in his hometown---Burlington，Vermont.He asked a local restaurant to stop offering straws with every drink order.It was a simple change.However，it would save money.And by doing that，the restaurant would cut down on its straw use by 50 percent.
   For the years that followed，Cress tried to spread his project across the United States.More and more restaurants agreed to join.They stop providing the customer with a straw unless he or she asks for one.Last April，Seattle became the American city to completely ban（禁止） plastic straws.
   Plastic pollution has been one of the most serious problems today.According to scientists，more than eight million tons of plastic end up in the ocean each year.Plastic straws are especially terrible.They make it easy for people to get comfortable with single-use plastics.
   After his project became popular，Cress took his findings on the road.He has since spoken to tens of thousands of students around the world.He wants to encourage more people to say no to plastic straws.
   "Focusing（聚焦） on straws is one simple step we all could take，" Cress says."And makes me feel that I，as a kid，could make a difference，too."
