Google Earth has recently released a set of new tools to illustrate the scale of climate change and deforestation. Along with greater detail than ever on the rainforests of Amazon, Madagascar and Borneo, they also include audio tours narrated by Al Gore. They do a great job of highlighting how breathtaking, and precious our rainforests are and how the protection of them is a crucial step in fighting climate change.
CleanTechnica has more information and of course the maps and tours can be found at Google Earth.
