Economic motives for extraction of natural resources prevent meaningful future use by encouraging present abuse for short-term profit, and accountability for the quantity of extraction and care of resources is virtually non-existent. Techniques for natural resource extraction are misused by limited interest groups to the exclusion of other areas of technology and of the needs of the world. These techniques are often the private property of corporations who will allow them to be used only for their own profit and under their control. National governments are often responsible for misuse of resources because they block overall planning and support foreign exploitation by corporations within their domain.
