It is essentially the environment—at least the physical environment—that surrounds (influences and is utilized by) a species population. - Wikipedia at: http://en.wikipedia.org/wiki/Habitat_%28ecology%29 Amy Sample Ward

Environmental preservation is the strict setting aside of natural resources to prevent the use or contact by humans or by human intervention. The distinct difference between conservation and preservation, is that conservation allows for the sustainable development paradigm, whereas preservation is complete restriction. - Wikipedia at: http://en.wikipedia.org/wiki/Environmental_preservation Amy Sample Ward
