“Knowledge is the only resource that grows when it is shared.” That frequently quoted observation by Club of Rome member Peter Johnston would be reason enough to devote a whole issue to growth and what grows, how it grows and why. Along with when it might be wiser to shrink and what the limits of growth are. These questions are closely examined in this first English-language edition of enkelfähig. Please read here the online issue. Or order your personal copy at enkelfaehig@haniel.de. In addition, this third issue is the first to offer an iPad version – available in a few days!
