Lights off

To help put all this in perspective, the average American generates about 41 pounds of CO2 a day. Sustainability estimates put the world’s ability to continuously absorb carbon emissions at about 9 pounds/person/day. By keeping lights off in my office and classroom (most of the time), I can reduce that “average” number by about 1.8 pounds a day, a 4.3-percent decrease from the average of 41 pounds/day.
