An interesting share (and discussion) is over on io9 concerning the U.N.’s Human Development Index, which rates the world’s countries on a scale of human development. Chuluun Togtokh, a Mongolian environmental analyst, wrote an op-ed in Nature in which he argues that sustainability should be a factor in the development index. That is, countries that pollute too much or use too many non-renewable resources have an artificially high (and unsustainable) development index score. When he recalculated the Human Development Index to include sustainability, the U.S. dropped from #4 down to #28 and Canada dropped from #6 to #24. Still at the top with the #1 position is my favorite country, Norway.
