You don’t have to be a scientist to solve big environmental problems. One foreign designer(设计师) is finding creative ways to make a change, and he’s inviting bikers to join him.

Daan Roosgaarde, 38, is a designer from Holland(荷兰). He uses creative ideas to improve city life. For his Smog(雾霾) Free Project, he designed a special tower that cleans air in Chinese parks. In Holland, he designed a shining bicycle path.

Now Daan and his team are working with engineers at a Chinese bike-sharing company to create a new product for public use. It’s an air-cleaning machine connected to a bicycle, which is part of the Smog Free Project. In smoggy weather, the machine would breathe in the dirty air in front of the bike and blow out a stream of clean air toward the biker’s face.

In winter, it’s common for thick clouds of haze(霾), caused largely by factory production, burning of coal and car emissions(排放物), to cover areas of China.

“Of course one tower and a few bikes won’t solve China’s air pollution problem,” Daan said. “But smog-free bikes are an exciting idea that will hopefully encourage communities to create greener cities.”

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we’re young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. 【小题1】

Remember these three words: reduce, reuse and recycle.

Reduce means “use less”. Don’t waste things. 【小题2】 Before we buy something new, think if it’s really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.

Reuse means “use again”. 【小题3】When we buy things, make sure that they last a long time. We should take care of them so that they’ll last, and we should repair them if we can instead of throwing them away and buying new ones. 【小题4】 It’s better to use a china（瓷）cup and a lunch box because you can use them again.

【小题5】 Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled and take part in the recycling projects. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
