The tiny little green line at the end of many emails "Do you really need to print this email?" is no longer enough to prevent us from printing tons of stuffs. It was time for a new viral message to be spread, and BBH Asia Pac came up with a smart idea to drive attention back: the USB chainsaw.




It was actually an amusing hoax. The idea is that everytime we hit the "CTRL + P" button on our keyboard we are actually activating the digital chainsaw to destroy trees. We print too much, and save too little. Make sure to download the chainsaw app on your computer which will play the horrible chainsaw sound effects whenever you press "CTRL + P" on our keyboard. Just a little gentle reminder the next time we print out those one-liner emails.
