I don't like naming people who inspire me heros.
I prefer the word visionars.
It's less autoritative, more informal, approachable.
I respect a lot of visionars.
Two of the most important ones for me are Braungart and McDonough, a biochemist and an architect.
Their revolutionary concept Waste = Food
, is profitable and successful in the real life.
Watch the doc**entary in which they explain and demonstrate solutions how factories can produce no waste products.
My step to follow their work is to set google alerts
for relevant keywords "Waste = Food" and "Braungart McDonough".
