Document Summary
The earth is closed to all inputs except the sun"s energy; hence, everything is connected to every- thing else and a global perspective is necessary. The term ecosystem combines the concept of a system a set of interrelated components that form a whole with that of ecology the study of organisms in their homes. Human activity has caused major damages to the earth"s ecosystems. The ecosystem impacts of humans" use of technology and energy are many. The recognition by political bodies of many of these impacts has led to the concept of sustaina- ble development. Acid rain the deposition on the earth"s surface of sulphuric and nitric acids formed in the atmos- phere as a result of fossil fuel and biomass burning; causes significant damage to vegetation, lakes, wildlife, and built environments.
