Ecological debt
（重定向自Ecological deficit）
Ecological debt is the level of resource consumption and waste discharge by a population in excess of locally sustainable natural production and assimilative capacity.
The term has been used since 1992 by some environmental organizations from the Global south. The first one to use this term was the Instituto de Ecologia Politica from Chile. J.M. Borrero, from Colombia, a lawyer, wrote a book on the ecological debt in 1994. This referred to the environmental liabilities of Northern countries for the excessive per capita production of greenhouse gases, historically and at present. Campaigns on the Ecological Debt were launched since 1997 by Accion Ecologica of Ecuador and Friends of the Earth.
