The September issue of Scientific American (Scientific American 303, 74 - 81 2010
doi:10.1038/scientificamerican0910-74) includes a graphically rich summary of information about the availability of natural resources and various other environmental matters. For those who don't have access to the magazine, there is also a interactive version (see below). While the information is the same, I didn't find the interface to be particularly user friendly. Yes .... the interactive version is right here. But, really, you might want to have a look at the good old print version (or its pdf cousin) :+) There are also a variety of related articles and web resources.
