1. William McDonough and Michael Braungart have started a movement they call waste = food. What do they mean by this?

2. What does the cradle-to-cradle concept mean?

3. If the concept of waste = food is even possible, how can companies achieve it? What examples can you cite of companies already doing it?

4. To be successful, these ideas must be adopted by both large companies and whole countries. Some might say that the current situation in China should give us hope. What's your oppinion?
