E. F. Schumacher was a profound and influential thinker and economist who, at a time of unlimited economic growth, challenged this ideology and proposed an approach to economics as if people mattered. He was one of the first to recognise the impossibility of continuous growth in a finite world, and warned against the worlds increasing dependence on oil. He was a key figure in the development of the environmental movement and was adamantly opposed to what he saw as violent solutions to economic problems, arguing against nuclear energy and advocating human-scale technology and organic cultivation.
