Toxicological trivia from January 16, 2012: Worldmapper is a collection of world maps, where territories are re-sized on each map according to the subject of interest.There are now nearly 700 maps. Maps 1-366 are also available as PDF posters. Use the menu above to find a map of interest. To learn a little more about this and other map projections read this: Worldmapper and map projections.For example, the map image: how is it related?:a) Surface of the countries;b) Births attended:c) Water resources.

Correct answer: c. See Map Nº 102. Water resources here include only freshwater, because saline (sea) water requires treatment before most uses. Only 43 600 cubic kilometres of freshwater is available as a resource each year, despite more than twice this amount falling as precipitation (rain and snow). Much is lost through evaporation. Those countries with higher rainfall often have larger water resources. Of all the water available, the regions of South America and Asia Pacific have the most.
People living in Kuwait use sea water that is processed at a desalination plant. As such Kuwait has no area on this map because there are no freshwater resources there.
