Michael Braungart is a German chemist who advocates that humans can make a positive instead of a negative environmental impact by redesigning industrial production.
A former activist who once lived in a tree as protest, he founded the chemistry division of Greenpeace and is now considered to be a visionary environmental thinker.
Braungart's first-class science mind leaves him sceptical about many popular environmental solutions. He is constantly explaining how much we need to know if we are to make the world a better place. And how much detail we already do know but which we sometimes stubbornly ignore.
