"Forestry means far more than growing timber. A forest encapsulates biodiversity, clean water and fresh air. And humanity." One of the challengers of conventional forestry is Mikael Karlsson, who has taken a new sustainable method to Sweden. Instead of clear cutting he advocates to gently harvest the high quality trees while maintaining the eco system intact. "A forest is at the same time the machine and the product. So be careful not to break the machine - because only big machines produce big trees."
