chopstick-tree: chopstick-tree

Short rationale (optional):
Every year Chinese consumes 45 billion pairs of disposable wooden chopsticks which equal around 25 million trees. DDB Shanghai recycled over 30 thousand used disposable wooden chopsticks from restaurants all over Shanghai. Washed them, process and collage them into a 5-meter-high-chopstick-tree, we then broke it down in the middle and then displayed the piece in the busiest district. Through the fallen chopstick-tree, we alerted the people that the use of disposable wooden chopsticks means the destruction of large numbers of trees.
