1 Day is an online survey app that allows users to "confess" about the choices they've made the day before, such as: their food, recycling, transportation, shopping etc. 

By scrolling and answering ten simple questions, the user discovers his influence on the environment.

 

Personally, I believe that by making small changes in his choices, a single person can make a serious change in the world.

 

The information in this app is taken from the UNs 2006 report Livestock's long shadow.
