that's true, but much of it is undrinkable and needs to be purified, energy cost needs to be considered and not all countries can afford especially now with escalating price of fuel.
I read that in countries like China there is are huge water problems, due to rapid pace of urbanization water is being re-directed from elsewhere to feed cities resulting in many huge lakes being dried up, there are more cases of famines now in the countryside. China is throwing billions of dollars to try to solve the problem, if there is no solution there will be no China growth story.
India cities are also growing and much of the infrastructure is in dismal condition not as bad as china but in time it will be.
Global population is estimated to grow to 9 billion in 30 years time this is going to put a big strain on drinkable water and resources of which much are already tapped out, we humans are our own disaster in the making our own growth stories will become our undoing, we are eating, using our way into a rendezvous with destiny.
