The human being has caused more and more transformations on nature through technology. Although its development aims to improve the quality of life, its use many times showed itself harmful to the human and to the environment. At the same time, the dimension that technologies have reached makes fundamental to call into question the relation between human, technology and nature, in order to think how man has act and how he can act in function of his goals, in relation to himself and in relation to the environment in which he lives. Thus, we take here as reference the thought of Heidegger and of his interpreters, believing in the richness of his contributions to the guiding of our questioning.
