UN overhaul required to govern planet's life support systemWashington DC (SPX) Dec 02, 2011 Reducing the risk of potential global environmental disaster requires a "constitutional moment" comparable in scale and importance to the reform of international governance that followed World War II, say experts preparing the largest scientific conference leading up to next June's Rio+20 Earth Summit. Stark increases in natural disasters, food and water security problems and biodiversity loss are just part of the evidence that humanity may be crossing planetary boundaries and approaching dangerou ... read more |
