The book Bioethics: theoretical foundations and applications brings together texts by experts of the field who intend to promote a more comprehensive and omnibus approach  of Bioethics, one which is capable of facing, in a differentiated way, the main ethical challenges of the globalized world. The inclusion of the so-called other, whether human or not, in all its diversity, is the leading thread that guides authors in achieving a closer look and listening to the demands that permeate the different forms of life that populate contemporary times.
