In 1972, three scientists from MIT created a computer model that analyzed global resource consumption and production. Their results shocked the world and created stirring conversation about global 'overshoot, ' or resource use beyond the carrying capacity of the planet. Now, preeminent environmental scientists Donnella Meadows, Jorgen Randers, and Dennis Meadows have teamed up again to update and expand their original findings in "The Limits to Growth: The 30 Year Global Update,"Meadows, Randers, and Meadows are international environmental leaders recognized for their groundbreaking research into early signs of wear on the planet. Citing climate change as the most tangible example of our current overshoot, the scientists now provide us with an updated scenario and a plan to reduce our needs to meet the carrying capacity of the planet.Over the past three decades, population growth and global warming have forged on with a striking semblance to the scenarios laid out by the World3 computer model in the original "Limits to Growth," While Meadows, Randers, and Meadows do not make a practice of predicting future environmental degradation, they offer an analysis of present and future trends in resource use, and assess a variety of possible outcomes.In many ways, the message contained in "Limits to Growth: The 30-Year Update" is a warning. Overshoot cannot be sustained without collapse. But, as the authors are careful to point out, there is reason to believe that humanity can still reverse some of its damage to Earth if it takes appropriate measures to reduce inefficiency and waste.Written in refreshingly accessible prose, "Limits to Growth: The 30-Year Update" is a long anticipated revival ofsome of the original voices in the growing chorus of sustainability. "Limits to Growth: The 30 Year Update" is a work of stunning intelligence that will expose for humanity the hazy but critical line between human growth and human development.

This book has become a favorite of K-12 teachers, university faculty, and corporate consultants. It provides short gaming exercises that illustrate the subtleties of systems thinking. The companion DVD shows the authors introducing and running each of the thirty games.The thirty games are classified by these areas of learning: Systems Thinking, Mental Models, Team Learning, Shared Vision, and Personal Mastery. Each description clearly explains when, how, and why the game is useful. There are explicit instructions for debriefing each exercise as well as a list of all required materials. A summary matrix has been added for a quick glance at all thirty games. When you are in a hurry to find just the right initiative for some part of your course, the matrix will help you find it.Linda Booth Sweeney and Dennis Meadows both have many years of experience in teaching complex concepts. This book reflects their insights. Every game works well and provokes a deep variety of new insights about paradigms, system boundaries, causal-loop diagrams, reference modes, and leverage points. Each of the thirty exercises here was tested and refined many times until it became a reliable source of learning. Some of the games are adapted from classics of the outdoor education field. Others are completely new. But all of them complement readings and lectures to help participants understand intuitively the principles of systems thinking.

Advocates and teachers often find it difficult to communicate the complexities of climate change, because the people they are trying to reach hold so many mistaken assumptions. They assume, for example, that when climate change becomes an obvious threat to our everyday lives, there will still be time enough to make changes that will avoid disaster. Yet at that point it will be too late. Or they assume we can use our current paradigms and policy tools to find solutions. Yet the approaches that caused damage in the first place will cause even more damage in the future. Even the increasingly dire warnings from scientists haven't shaken such assumptions. Is there another way to reach people? The simple, interactive exercises in The Climate Change Playbook can help citizens better understand climate change, diagnose its causes, anticipate its future consequences, and effect constructive change. Adapted from The Systems Thinking Playbook, the twenty-two games are now specifically relevant to climate-change communications and crafted for use by experts, advocates, and educators. Illustrated guidelines walk leaders through setting each game up, facilitating it, and debriefing participants. Users will find games that are suitable for a variety of audiences-whether large and seated, as in a conference room, or smaller and mobile, as in a workshop, seminar, or meeting. Designed by leading thinkers in systems, communications, and sustainability, the games focus on learning by doing.
