This simple sticker can make people aware that the toilet paper and paper towels come from tree. Apparently reminding people of this (also apparently) oft-forgotten fact can help protect the environment. Go order some stickers and put them up in your local coffee shop.

Testing shows a “These Come From Trees” sticker on a paper towel dispenser reduces paper towel consumption by ~15%
A typical fast food restaurant with two bathrooms can use up to 2000 pounds of paper towels a year
The average coffee shop uses 1000 pounds of paper towels a year
A single tree produces around 100 pounds of paper
