Value of Maintaining Natural Ecosystems: Preservation vs. Conservation

I need to compare and contrast the practices of preservation and conservation as they relate to the maintenance of ecosystems. I also need to discuss the concept of “natural regulation." Use examples of these practices from your local area (e.g., natural swings in sizes of animal populations, natural occurrence of grassland and forest fires, and natural succession of fallow farmland and waterways). Use a minimum of two outside references.

Environment vs Economy

Should environmental groups play a role in preserving those regions threatened by human encroachment, even if it is jeopardizing interests of the economic growth? How should the interests of competing groups be balanced?

I need help differentiating between conversation and preservation.

Help differentiating conversation and preservation. Do you believe that humans can harvest forest resources in an environmentally friendly way? Or, should national forests be left in their natural state in which resources are not used to benefit humans? To which side are you inclined?
