Résumé :	Pollution, depletion, degradation, erosion, contamination, poisoning-these are terms usually associated with heavy industry and cities, not with our green countryside of fields and scattered farmsteads, but these are all terms that are applicable to the environmental problems caused by conventional US agriculture today. Agriculture has become very like traditional manufacturing industries, with many of the same environmental risks and waste-disposal problems among its side effects. This analogy has a dangerous flaw : because of agriculture’s extensiveness and its use of toxins that are broadcast into the environment, its impacts are more wide-ranging than those of most other industries. In fact, they are so widespread that they are generally overlooked. This chapter explores the major ecological problems of agriculture : soil erosion, loss of genetic and biotic diversity, depletion of energy and water resources, chemical contamination of water, workers and food and creation of new and more serious pest problems. The breadth and seriousness of these problems present strong evidence that current agricultural practices are ecologically unstainable.
