In the 1970s, the American biochemist and oncologist Van Rensselaer Potter coined a new word, 'bioethics', to describe an emerging discipline bringing together the life sciences and ethics. This new field, for Potter, represented "a bridge to the future" of humanity. Fifty years later, the "global bioethics" that Potter theorized in the 1970s has largely been reduced to clinical ethics. Meanwhile, the role of bioethics in what is probably the most important debate for the continuation of human life on the planet, the environmental debate, has been minimal. In view of the dangers that threaten life as we know it today, and consequently even human continuity on our planet, it is imperative to ask what kind of change is needed to avoid such risks, how to achieve it, and what the role of bioethics should be in this transition.
