How to reconcile a high quality of life and respect for natural resources? The next report to the Club of Rome (1995), the authors of which are world-famous experts in the field of environmental protection, is devoted to finding an answer to this question. The book brought to the attention of readers is a revised version of the mentioned report. The main content of the book is devoted to substantiating the concept of “resource productivity,” by which the authors understand the ability to live twice as well and at the same time spend half as much. Hence the title of the book. The book is addressed to a wide range of readers.
