The aim of this paper is to evaluate the planetary socio-ecological crisis guided by two axial ethical principles and an ethical-political concept derived: first, from the principle of responsibility and of care for the vulnerable being (current and future human beings and all other life on planet); second, the principle of ecological justice in its three complementary aspects: global justice (socio-economic inequalities at the global level); both justice intergenerational (future generations) and interspecies (principle of biospherical hospitality towards other living beings); and the ethical-political concept of ecological citizenship in a global society.1en-USsocio-ecological crisisenvironmental ethicsprinciple of responsibilityglobal justiceecological citizenshipArtículo
