A few years ago, I did the math on planting trees to offset your carbon emissions, and came up with an affordable $15/year/person for the average US resident: http://shindyapin.tumblr.com/post/141034501197/climate-change-solution-simplified http://shindyapin.tumblr.com/post/141034501197/climate-chang...
