There are enormous latent environmental implications in the laying of pipelines, both for the communities through which they pass and for those to which they transport their energy resources. A pipeline corridor frequently crosses undeveloped areas, sensitive environments, agricultural lands, or timberlands. The heavy construction activity taking place within this corridor may interrupt the migratory patterns of caribou, elk or other large animals, or the fish spawning grounds on which local hunting and fishing activities depend. Gravel mining sites impact hillsides or stream beds with scars; and haul roads built to transport materials and equipment cause impacts both inside and outside of the pipeline corridor.
A 1982 study estimated that over 133,000 miles of pipeline were being constructed or planned; if stung together, they would stretch around the globe 5 times.
With proper pre-planning the destructive environmental impacts of pipelines can be minimized and their constructive impacts can be used to improve living conditions for people around the world by making access to much-needed oil more readily available.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
