Book excerpt: Natural history, the deliberate observation of the environment, is arguably the oldest science. From purely practical beginnings as a way of finding food and shelter, natural history evolved into the holistic, systematic study of plants, animals, and the landscape. This book chronicles the rise, decline, and ultimate revival of natural history within the realms of science and public discourse. It charts the journey of the naturalist's endeavour from prehistory to the present, underscoring the need for natural history in an era of dynamic environmental change.
