Persuasive Ecologist (Press, 21 January 1989)

In the book "The Machinery of Nature," Paul Ehrlich explores the crucial relationship between humanity and the environment, presenting a compelling case for ecological awareness and conservation. Published in 1988 and reviewed by Naylor Hillary in January 1989, the book serves as a response to the growing scepticism surrounding the conservation movement's predictions about environmental damage caused by human activities. Ehrlich's calm, methodical approach demystifies the often contentious debates regarding ecological issues. He stresses the importance of listening to informed voices in the conservation dialogue rather than disregarding them as alarmist or anti-development. By employing examples from his own background studying butterflies in California, he injects an element of enjoyment into the study of ecology. His narrative spans a wide range of topics, using various species and behaviours to highlight evolution's significance in understanding ecosystems. For instance, Ehrlich discusses the territorial nature of the paradise fish in Tahiti, where gender roles shift rapidly in response to changes within their hierarchy, illustrating the complexities of evolutionary strategies. Through such examples, he aims to foster a deeper appreciation among lay readers for the intricate connections that define ecosystems and the role humans play within them. Ehrlich succinctly summarises his thesis: evolution has shaped not only humans but also every living organism and environmental aspect around us. He argues that understanding these systems is vital for both awareness of our place in the world and for the preservation of the ecosystems that sustain us. Despite the potential for optimism, he concludes with a warning about the general public's lack of appreciation for the importance of ecology, suggesting that this ignorance poses a significant threat to the future of conservation efforts. Overall, "The Machinery of Nature" serves not only as an educational resource but also as a clarion call to appreciate and protect the natural world, with Ehrlich's engaging style making the concept of ecology accessible and relevant to readers. His gift for communication shines through as he strives to enhance understanding and respect for the environment, advocating for a collective responsibility in its preservation.
