Blast furnaces with Machiennes at the XIXe century
Medium in which the man evolves, the environment relates to on the one hand natural sometimes phenomena, whose man is not aware, and on the other hand the living conditions, i.e. the way in which the man arranges himself with the natural environment.
The concept of environment is recent: it appears in certain countries at the time when nature “is not only almost completely tamed”, but also endangered, and even destroyed. The destruction threatens of the species as well vegetable as animal, including the men. Indeed, the resources of nature appear inexhaustible as long as they have the possibility of being regenerated.
The natural environment in which we live is a system of balance between destroying processes and regenerating processes who regulate the life of all the mineral species, animal, vegetable.
