This is a funny poster advocating software piracy to help prevent global warming. The logic is that you waste fuel when driving to the nearest computer store to buy software.
Instead of driving to get CDs, buying pre-packaged software from mega-corporations and wasting energy, you can help fight Global Warming by using P2P.
Most software companies now offer a download version of their software packages or you can order them by postal mail, why should you drive down to get the CDs. But do turn off the computer screen at night to combat global warming.
