Résumé
Environmental law, whose purpose is to respond to the ecological urgency, is based on technical aspects, i.e. legal; obliterating the anthropological aspects of human diversity. It is from the assumption of an interweaved society-environment viability within the biosphere, that the legal approach can be revisited and re-established based on the adequacy of (social) usefulness to an (ecological) function, based on field studies. The adoption of a paradigm based on an approach of social viability within the Earth system, i.e. coviability, has resulted in a socio-ecological link being highlight and which needs to be formalized in legal regulation by though an adequacy between human needs and the ecological function.
