Geochemical Engineering: Principles and Case Studies
- 101 Downloads
It is a common misconception that environmental problems have started with the advent of industrialization; situations that we would now describe as environmental problems have existed on earth since its origin. We need only think of the large amounts of S02 and other toxic gases that are emitted by certain volcanoes. Similar point emissions in an industrial plant would almost certainly cause the plant to be closed for environmental reasons. It is obvious that the accumulated emissions of all volcanoes during geologic time would have seriously damaged the earth’s ecosystems unless the damage were undone by geochemical processes.
