Planet Earth: American Swamps and WetlandsThis book discusses the indispensable role wetlands provide to the American environment during ancient primeval times and now. Emphasis is presented of how throughout the millions of years since living things first solved the problems of a terrestrial existence, wetlands have remained a pivotal part of the earth's biosphere, important in terms of habitat and the food they provide for wildlife and in terms of the abundance of food they provide for man. |
