The physiology of digestion considered with relation to the principles of dietetics (Edition2)

From the banks of the Nile to the vast currents of the Atlantic, the story of humanity has always been a story of water. Civilisations were born on riverbanks, empires rose through maritime trade, and wars were fought over control of streams and seas. Yet too often, history is told through kings and battles, neglecting the deeper current that shaped them all. This book reveals how rivers and oceans forged human destiny. It brings to life the Indus cities that vanished when monsoons failed, the Mediterranean that became a liquid continent of culture and conflict, and the Indian Ocean whose monsoon winds created the world's first global trade network. It shows how water built not just economies and empires but philosophies, faiths, and revolutions. For readers drawn to history, culture, and the environment, this is both a sweeping narrative and a fresh lens. Along the way, it illuminates urgent questions of our own age: the future of water conflicts, the threat of climate change to Asia's great rivers, and the rising seas poised to redraw coastlines. - Discover how hydrology shaped the rise and fall of civilisations - Understand the links between trade routes, politics, and ecology - See today's global crises through the long lens of environmental history By the final page, readers will not only know history differently but see the world anew: as a civilisation of water, always at the mercy of its eternal current.
