The Legislature further finds and declares that current conservation and development practices may conflict with the public interest of present and future generations due to:

1. (a) An insufficient understanding of the long-range implications of land use practices as they affect the zone and the region.
2. (b) The uncoordinated and fragmented nature of public and private planning of development and conservation activities within the zone.
3. (c) The lack of a comprehensive plan and program to provide for conservation and development of the zone in the best public interest.
4. (d) The fact that no governmental mechanism exists for studying and evaluating individual projects as to their effect on the entire zone and region.
