Planting with printers: Chicago man recycles paper with electronic forestry

In his spare time Chicago resident Joe Miller runs what may be the coolest eco-friendly company with the coolest name ever. Print-A-Forest makes a free computer software that turns your  routine printing projects into a plant-a-tree fundraiser. By getting a small  message from plant-a-tree sponsors across the bottom of your printed pages, you pay for planting trees. An example: “Powered by State Farm” could appear on the bottom of the page if the insurance company sponsored the planting. Pretty simple.
