Carlo Petrini, started the slow movement in 1989. I heard of him through a friend of mine in the 90’s, who was very into the slow food movement.
Carlo explains very well why the approach must be holistic, and this applies to other systems as well. He says:
You can’t talk about food without talking about environment,
You can’t talk about health without talking about the quality of food.
Everything is connected!
Food is culture, is environment, is health, is spirituality.
It is an extraordinary and exciting job!
