Maximising the underground location of the subway station this poster sits in, by use of carved tree, real dirt, and styrofoam boxes we try to show the environmental damages caused by non-biodegradable products.

The traffic in Shanghai Metro is 2 million passengers daily. After the work was installed, immediately it created a huge curiosity among commuters. Over 30 newspapers, 4 TV stations, 1 radio station and 10 websites reported on the work, and that helped to spread the concept of ‘Don’t Use Non-Biodegradable Products” to a bigger audience. It was voted the “Best Ad” by commuters in January 2007, from JCDecaux’s survey. Now many shops in Shanghai have started to provide biodegradable plastic bags; white-collars refuse to use Styrofoam containers. People in Shanghai started to have a better understanding on what GREENPEACE do, and why they should care about the environment.
