Treehugger’s 22 Most Amazing Maps Changing How We See the World is a collection of environmental maps they saw and liked over the past year. “The year 2009 brought us some incredible maps, illustrating things like how the earth’s carbon cycle works which then unveiled new understanding about how carbon emissions from one country affect other parts of the planet; or how wilderness is disappearing, which pointed out some surprising conclusions about how little space humans actually inhabit while still impacting massive amounts of the globe.” Via geoparadigm.
