Question

Air pollution is a big problem for cities. Many people are dying from it. But how can we tell the air quality(质量) is good or bad?

Joris Lam has invented a birdhouse that can tell us about the air quality. On a tree next to a canal (运河) in Amsterdam, a small birdhouse will shine bright green when the air is clean. If you are standing near the birdhouse, it will also give you a free Wi-Fi connection. So Joris’s birdhouse is called TreeWifi. It can be put on a tree around your house to test the air quality. People can see a screen with information about local air quality and how to improve it. TreeWifi is a simple way for people to know about the air pollution around them. If the birdhouse doesn't shine, people will care more about the environment. It tells them to change their lifestyles. For example, to protect the air, they can ride bikes instead of driving cars.

Joris and his team are trying to make some changes to the birdhouse. In the future, the heat of its green light will be used to keep birds warm in winter.
