Around the world in 80 people

Three examples of entrepreneurs who dream of changing the planet that Mathieu Le Roux and Sylvain Darnil found in the course of their fifteen-month world tour included profitable hospitals which provide free care for two-thirds of their patients and use artificial limbs which are fifty times less expensive than the usual price ; a bank which helps three-quarters of its customers to avoid situations which might lead to severe poverty ; and a chemist who has invented a new business model by which he can recycle a polluting product indefinitely. Sustainable development is often thought to be a costly pipe dream. Mathieu Le Roux describes eighty case studies of men and women who are carrying out surprising projects. Contrary to what one may think, he shows that sustainable development is an opportunity for entrepreneurs.
