What can we tell about water resources in the ME from this map?Water ScarcityWater is the most precious natural resource in the M.E.Sources, such as rivers, aquifers (Saudis get 70% of water), etc., are being rapidly depleted as population in the region soars (grows).UN predicts that by 2025, 18 countries in the M.E. and North Africa will be water scarce.Millions lack access to an adequate supply of clean, available water.Impact of water scarcity on M.E. countries???Water usage in the M.E.
