If there's one term that's all the rage, covered in radio and TV broadcasts, national and international meetings, scientific days, public squares, and the object of proliferating swarms of NGDOs and associations, it's the environment.A great deal of funding is earmarked and intergovernmental agreements are signed in this sector. By virtue of its polysemic, complex, globalizing and totalitarian nature, the environment extends to all sectors of human life. That is, health, social (man in his relations with other members of society), economic, demographic, climatic, hydrographic, fauna and flora, etc.Before the 1970s, man had no concern for the environment. It was his negative impact on the environment through over-hunting and fishing that led to the disappearance of or threats to several species, but it was above all the destruction and degradation of the natural habitat that had the greatest consequences.
