Read here, here and here. Most people, on every side of the AGW debate, would agree that chopping down a rain or boreal forest to promote development of renewable fuels is an extremely bad idea in terms of earth's climate. Unfortunately, the failure of Copenhagen also keeps these forests at risk because of the previous idiotic legislation/regulations previously agreed upon or promoted (Kyoto, cap & trade, U.S. renewable energy schemes, etc.).
Because of the Climategate scientists fraudulent science, and their propaganda of imminent world catastrophes if nothing was done about CO2 emissions immediately, it caused all the focus to be on a questionable, nebulous problem with an impossible political/economic solution, instead of actually focusing on real world climate and environment problems that could be solved. Climategate lies cause trees to die.
