Researchers this week reported on what they claimed was the "first systematic global analysis," quantifying the environmental impact on poor countries of the high consumption levels of richer countries. While, for example, greenhouse emissions from low-income countries cost $740 billion in damages to rich countries, they in return have imposed $2.3 trillion of damage, reports The Guardian.

" 'At least to some extent, the rich nations have developed at the expense of the poor and, in effect, there is a debt to the poor,' said Professor Richard Norgaard, an ecological economist at the University of California, Berkeley, who led the study. "That, perhaps, is one reason that they are poor. You don't see it until you do the kind of accounting that we do here.' "

In all, the researchers claim, the burden of the environmental "footprint" of high-income nations falling on low-income countries is greater than their entire financial debt, or about $1.8 trillion. NBC reports:
