"Our house burns and we look elsewhere (...) the French must change their way of life" (Excerpt from the speech of Jacques Chirac in September 2002 at the second summit of the Land of Johannesburg). Is the current environmental crisis not worrying you? Climate disruption and greenhouse effect, air and water pollution, oil spills, contaminated soils, mad cow disease, disappearance of many plant and animal species, uncontrolled spread of artificial transgenic constructions. The originality of the human species in relation to others is no longer its intelligence as it has long been believed, but its capacity to destroy in full consciousness its own environment. What world do you want to leave to your children? Each of us is responsible for the nuisances he creates and will affect future generations.
