PROGNOSIS: DISASTER SECOND EDITION is a book about human induced environmental change and disease. Climate change, global warming and deforestation threaten human, animal, and plant populations with diseases more virulent than previously known. Most of this book deals with diseases influenced by climate change and how humans influence their creation and spread. This book will be useful as a reference on disease and environmental science, and as a call to action. Unless we take active measures now to stop pollution and greed, all life on the planet is doomed.
