地球精致的生态是统一的主题。 每个部分都探讨了生物群落的独特生态结构，并揭示了人类干扰如何破坏平衡，并破坏了我们赖以生存的生命支持系统。参考页组成了每个部分的第一部分，其中的地图显示了生物群落的范围， 并在气候，自然历史和生态学上进行了传播，解释了生物群落的工作原理。 随后的传播探索了人类活动所带来的威胁，并表明了积极的努力通常可以如何克服这些威胁并保护生物群落。 在整本书中，壮观而私密的摄影作品展示了生活世界无穷无尽的多样性和美丽，提供了令人信服的视觉依据，以支持本书的核心信息。
Earth's delicate ecology is the unifying theme. Each section explores theunique ecological structure of a biome and reveals how human interference can upset the balance and damage the life-support systems upon which our existence depends Reference pages make up the first part of each section, with maps showing the extent of the biome, and spreads on climate, natural history, and ecology explaining how the biome works. Subsequent spreads explore the threats arising from human activity and show how positive efforts can often overcome the threats and preserve the biome. Throughout the book, spectacular and intimate photography showcases the living world's endless diversity and beauty, providing a compelling visual argument to support the book's core message.
