In a world of increscent complexity, the problems prevention becomes a priority, given that every day turns more expensive to revert the consequences of the procedures that deteriorates the environment we live in. The enforcement of the green chemistry principles enables to design production phases that are friendlier with the environment and becomes a tool for the improvement of the life quality for the people around these production centres. The logical sequence this book presents allows to reflect on the evolution of the decision making in big and small industrial plants, on big catastrophes that could have been avoided, on the impact that products and wastes have in the environment and on the paradigms changes related to the environmental problem. This production will be useful for chemistry and similar disciplines professionals and also for students of different careers related to those. Química verde. Enfoque sistémico constitutes an input to ontological, epistemological and axiological discussion of chemistry and his concrete applications. Ester Mercedes Ocampo
