On March 18 – 19 in New York, we created a massive event where thousands of New Yorkers traded in their paper cups for reusable mugs. Artists used the individual paper cups to create a giant mosaic image of a sequoia three – representing the vast number of trees we can save if we all made one small change.

During the event, thousands of people traded in their paper cups for reusable mugs. On Facebook, 790,000 fans participated from around the world. And as a result of the documented event, over one million people brought a reusable mug to Starbucks on April 15th.
