We address the ethical causes of the global ecological crisis we are currently undergoing, along with the expansion of the instrumental reason that is typical of modernity and the critics arisen from ecological ethics and feminism. Helping to solve the ethical crisis found in the base of ecology, with the intention of universal rationality, is possible from bioethical approach: utilitarianism and radical neoliberalism are useless, and maybe the foundations of our ethical duties with the nature and the rest of the living creatures may be found in the proposals of the dialogic ethics, neoaristotelian perspective and personalisme.
