Production of natural fibres for cloth used in garments may not be able to keep pace with demand from a growing world population. This is true of plant fibres, from cotton for instance, and animal hairs like sheep's wool and many furs. Production of artificial fibres such as the polyesters, and fabrics such as vinyl, may be subordinated to needs for chemicals in construction and in industrial applications. In addition, world weather is showing continued instability and seasonal cycles are interrupted by cold spells, hot spells, storms and droughts. This increases the demand for clothing that normally would not often be worn in certain latitudes, for example: tropical, light weight fabrics in the northern temperate zone; and heavier garments in the southern hemisphere.
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.
