Answer 1

You should be able to find everything you need to know from the reports and charts on this site - http://www.worldwater.org/data.html

Answer 2

WATER

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

overpopulation of an extra 70 million people a year (increasing all the time )and expanding agriculture ,which uses 70% of available potable water supplies ,has brought the good(sweet) water suplies to critical levels ,some countries have been in trouble already quite a while .

now climate change and desertification because of irresponsible agriculture ,overgrazing and deforrestation is damaging world fresh water production .

it is a good reason for concern and if we do not rectify matters by changing agricultural methods ,reforrest ,stop deforrestation,become more economic with water use ,stop producing more people ,stop wasting and contaminating water, we will be in serious trouble all round
