Sachs emphasizes that the implementation of technical and economical strategies to solve the problem are to be made by politicians, industries and people in general altogether.

Sachs believes that politicians are really concerned about the crisis, but they need economical support.

Sachs concludes that if the government, the industries and people don't help, the consequences will be seriously felt.

Sachs thinks that technical and economical solutions are impossible on their own, unless people get involved.
