The man of the 21st century is discovering himself with dismay, even anguish.As a result, he is faced with uncertainties about the effects of his actions, or with serious environmental threats.That's why it's important to rethink an alternative for a better world. Indeed, moving towards sustainable development is everyone's responsibility, and quality, safety and the environment could be the guarantor of this ambition.This book on QSE deduces the rationale for a responsible society. And this responsibility will enable sustainable development.For the salvation of our century, it's a question of finding a compromise between human activities and the protection of ecosystems, between the needs of current and future generations, and even between countries and regions - as globalization requires.Without ambiguity, this work allows us to see things differently and to assume our commitments to future generations.
