• 25% of the planets surface is land
  75%of the surface is water and it is rising
  
  ------------------------------...
  
  97%of the Earths water is salt
  
  fresh water is only 3% of all the Earths water
  most of it is beyond out reach
  
  now much ice is melting and running into the seas fresh water lost for ever.
  
  STORAGE or Location of % of the fresh water
  ice and glaziers 74%
  groundwater 800 meters + 13.5 %
  groundwater less than 800meters 11.o%
  Lakes 0.3%
  soils 0.006%
  Atmospheric in circulation 0.0035%
  rivers 0.03%
  
  
  frozen land or permafrost is not included and represent an unavailable storage of 40%
  
  so of the 3% about 11.6 ,is easily available to us ,in rivers, lakes and ground water surface aquifers,more and more of this is becoming contaminated 0% 0 Votes
