One for James http://www.earthday.net/footprint/index_reset.asp?pid=379818142458096 Assesses (or attempts to) the amount of viable area in hectares required to sustain you. Available world hectares of biologically productive land is 1.8 per person. My score was 4.8 hectares. My country's average was said to be 7.6. I was surprised to be rated so low wrt my country average and not at all surprised wrt world average. I've never attempted to assess my "carbon footprint". I'm not at all convinced, as you might expect, that such measures are meaningful or useful, although I'm happy with the idea of attempting to reduce resource utilisation. My hope long term is to have a large and negative one, regardless of the usefulness of the measure. If things work out as I hope they may in the near future then I should be on the way to producing a personal extremely large negative carbon footprint. Probably arguably a large negative ecological one too. Working on the theory that if one aids a large number of people in reducing theirs then one is due a percentage of the "spoils". I'll tell you about it if it comes to pass. Russell -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
