As we know water is very essentile thing for daily life. The given charts indicate the information about the amount of water quality which supplied to two regions all the world. we will summarise the information and we will find the key feacture.
To begine with, water supply is the most important thing. Firstly, if we compair the graph than we can se that in 1990 Australia was having higher supply than the South East Asia because in 1990 Australia was having near to 80% of supply and in South East Asia was having only 38% of water supply but after 20 year in 2010. The supply of water has being increased to 99% and South East Asia increased to 66% which is huge difference. secondly if we see in cleanliness than quality has changed after 20 years like in 1990 the water quality in Australia was 66% which has changed to 83% in year 2010 but in opposite South East Asia has dcreased quality like in 1990 the quality was 40% and goen down to 27%.
In conclusion we can say that the supply of water has increased in 2010 than the 1990. but if we llok in cleanliness graph then we had noticed that South East Asia had get decreased water quality up to4% than the perious one.

To  
begine
 with,  
water
  supply
 is the most  
important
 thing.  
Firstly
, if we  
compair
 the graph than we can  
se that
 in 1990 Australia was having higher  
supply
 than the South East Asia  
because
 in 1990 Australia was having near to 80% of  
supply
 and in South East Asia was having  
only
 38% of  
water
  supply
  but
 after 20 year in 2010. The  
supply
 of  
water
 has  
being increased
 to 99% and South East Asia increased to 66% which is huge difference.  
secondly
 if we  
see
 in cleanliness than  
quality
 has  
changed
 after 20 years like in 1990 the  
water
  quality
 in Australia was 66% which has  
changed
 to 83% in year 2010  
but
 in opposite South East Asia has  
dcreased
  quality
 like in 1990 the  
quality
 was 40% and  
goen
 down to 27%.
In  
conclusion we
 can say that the  
supply
 of  
water
 has increased in 2010 than the 1990.  
but
 if we  
llok
 in cleanliness graph then we had noticed that South East Asia had  
get
 decreased  
water
  quality
 up to4% than the  
perious
 one.
