Book Description
An urgent and illuminating portrait of forest migration, and of the people studying the forests of the past, protecting the forests of the present, and planting the forests of the future. Forests are restless. Any time a tree dies or a new one sprouts, the forest that includes it has shifted. When new trees sprout in the same direction, the whole forest begins to migrate, sometimes at astonishing rates. Today, however, an array of obstacles—humans felling trees by the billions, invasive pests transported through global trade—threaten to overwhelm these vital movements. Worst of all, the climate is changing faster than ever before, and forests are struggling to keep up. A deft blend of science reporting and travel writing, The Journeys of Trees explores the evolving movements of forests by focusing on five trees: giant sequoia, ash, black spruce, Florida torreya, and Monterey pine. Journalist Zach St. George visits these trees in forests across continents, finding sequoias losing their needles in California, fossil records showing the paths of ancient forests in Alaska, domesticated pines in New Zealand, and tender new sprouts of blight-resistant American chestnuts in New Hampshire. Everywhere he goes, St. George meets lively people on conservation’s front lines, from an ecologist studying droughts to an evolutionary evangelist with plans to save a dying species. He treks through the woods with activists, biologists, and foresters, each with their own role to play in the fight for the uncertain future of our environment. An eye-opening investigation into forest migration past and present, The Journeys of Trees examines how we can all help our trees, and our planet, survive and thrive.

Author: Historical epistemology and the making of modern Chinese medicine
Author: Howard ChiangPublisher: Manchester University Press
ISBN: 1784991910
Category : History
Languages : en
Pages : 387
Book Description
This collection expands the history of Chinese medicine by bridging the philosophical concerns of epistemology and the history and cultural politics of transregional medical formations. Topics range from the spread of gingko’s popularity from East Asia to the West to the appeal of acupuncture for complementing in-vitro fertilisation regimens, from the modernisation of Chinese anatomy and forensic science to the evolving perceptions of the clinical efficacy of Chinese medicine. The individual essays cohere around the powerful theoretical-methodological approach, 'historical epistemology', which challenges the seemingly constant and timeless status of such rudimentary but pivotal dimensions of scientific process as knowledge, reason, argument, objectivity, evidence, fact, and truth. In studying the globalising role of medical objects, the contested premise of medical authority and legitimacy, and the syncretic transformations of metaphysical and ontological knowledge, contributors illuminate how the breadth of the historical study of Chinese medicine and its practices of knowledge-making in the modern period must be at once philosophical and transnational in scope.
