The "Law of the Sustainability of Living Systems", developed with other experts, explains and specifies the principles of sustainability: It says that living systems are only sustainable if they achieve a balance between productivity and elasticity. Balance, therefore, between short-term benefits of long-term existence. Just like that of Yin and Yang - not an "either - or". We violate this law criminally. We have driven most living systems out of balance, making them non-sustainable.. Mono-cultures of all kinds, for example, emphasize short-term benefits and are not even sustainable in the short term without massive additional costs, as Lietaer shows with the example of forests and today's monetary system. The book calls on readers to ensure that this law of sustainability is recognized and complied with. Both as individuals and as leaders in business and politics, readers are challenged to balance the short-sighted overvaluation of rapid return with the preservation of resilience.
