Le fondateur de Worldchanging.com, Alex Steffen nous explique à quel point il est vital de réduire l'empreinte écologique de l'humanité, à l'heure où le mode de vie consumériste occidental  s'étend aux pays en développement.

Alex Steffen imagine un futur durable

Humanity is consuming resources at a rate that would require up to ten Earths if everyone lived like North Americans. As billions more people seek a higher quality of life, the planet faces mounting ecological and social pressures. Innovative solutions, from car-share clubs to landmine-detecting flowers, show that prosperity and sustainability can go hand in hand. The path forward lies in leapfrogging old technologies, supporting collaboration, and embracing bold new designs for cities and communities.
