"The human brain is neutral, it does not distinguish between right and wrong, ethical and non-ethical behaviour. It only learns and optimizes whatever is repeated" Talking about risks implies talking about decisions, those we do make and those we don't. Learning how to manage those risks requires considering the decision content and, fundamentally, understanding what drives us to "make" a decision. We would all probably agree that the current state of the global ecosystem demands urgent action. It seems that changing radically the way in which we decide is necessary for all the species of the planet to keep on coexisting. But, how do we do it? Why are we still chained to a decision-making model that has shown to be poor in terms of sustainability and ethics? It may be that the answer lies in our own evolution, but what kind of biological and cultural evolution process transformed humans into "not so good" decision-makers at recognizing and becoming responsible for the impacts and potential responses of the ecosystem towards their decisions? This book approaches these questions with a view to understanding who has been and who currently is the Western decision-maker. It proposes a paradigm shift that makes "ecosystemic" management of decisions and risks possible. Through a deep reflection about the topic, Rita Carrizo -the author- seeks to connect contributions from the fields of biology, genetics, sociobiology, neurosciences, systems thinking and ontology of language.
