Book excerpt: "The Classic Maya civilization thrived between 200-950 CE in the tropical forests of eastern Mesoamerica before undergoing a period of breakdown and transformation known colloquially as the Classic Maya Collapse. This book draws on archaeological, environmental, and historical datasets to provide a comprehensive overview of Classic Maya human-environment relationships, including how communities addressed challenges wrought by climate change. Researchers today understand that the breakdown of Classic Maya society was the result of many long-term processes. Yet the story that continues to grip the public imagination is that Maya civilization mysteriously "collapsed." This book shifts the focus from the Classic Maya "collapse" to the multitude examples of adaptive flexibility that allowed Pre-Colonial Maya communities to persevere in a challenging natural environment for over seven centuries. This idea is so enthralling partly because it makes people think about the impermanence of present-day society. A misunderstanding of Maya conservation practices persists in non-academic circles to the disservice not only of the Pre-Colonial Maya, but also to their descendants living in eastern Mesoamerica today. Although the Classic Maya civilization did not leave behind much in the way of secret environmental knowledge for us to rediscover (that is unfortunately rarely how archaeology works), a critical lesson that can be learned from studying the Classic Maya is the importance of socio-ecological adaptability-the ability and willingness to change cultural practices to address long-term challenges"--
