Dear Lord Stern, Glad you contributed significantly on important aspects. It is high time the rich (memebrs of societies as well as nations) recognize their ecological footprints in their choice consumption and address the global warming as well as related environmental problems sensibly. Cutting down on red meat consumption, for example, stands to contribute toward reduction of a fifth of greenhouse gases almost costlessly. Indidivual and public polcies need to pay much greater attention to consumption-orinted greehouse gas rgimes and their containment with fiscal measures wherver needed. Thank you very much, Dr P K Rao, Princeton, USA.
