Environmental degradation, particularly related to climate change, highlights the urgency of seriously reducing per capita energy consumption. Solutions exist; they concern the habitat, the transports, the daily life ... and this, for each of us
Do you know your "ecological footprint"? The environmental "weight" of your earthly existence? The stigma that indirectly inflicts on the planet? By evaluating the lifestyles and consumption of each, a test (1), developed by several NGOs - including WWF France - allows to estimate the amount of energy, land and water needed to produce this that we consume and absorb what we throw. France's ecological footprint has grown by 48% in forty years, while its population has increased by only 27%. Clearly, if every Terran lived like a Frenchman, it would take three planets to provide for our needs. Eloquent.
