Another problem confronting society today is the degradation of the world’s biosphere and ecosystems. Economic development has been pursued relentlessly to the detriment of the environment that supports human life and biodiversity. Thus, in response to the ecological crisis, the 1992 Earth Summit in Brazil formulated a set of policies meant to conserve the earth’s resources for the benefit of present and future generations, distribute wealth equitably, and reconcile economic growth with the environment’s capacity for regeneration. Abundio R. Babor, however, in his essay titled “A Bucket Half Empty: A Critique of the Notion of Sustainable Development as a Paradigm for Environmental Sustainability,” discusses the inadequacies of these policies in protecting and conserving the earth’s non-renewable resources. He argues that the unbridled exploitation of these finite resources necessarily degrades the world’s biosphere and ecosystems. – F. Ramirez (ed.)
