2.8
 billion people face water shortage now. Nuclear power plants(370000 
megawatts capacity today) alone run on 1.5 billion cubic meters of water
 per day which is however badly required for these 2.8 billion people to
 live! And the consumption of water by the nukes is wasted fresh water 
because the nuclear energy programme consumes much more energy than the 
electricity it delivers to society outside the nuclear industry year 
after year. And the fresh water is converted to radioactive water which 
remains poisoned for 400 thousand years! Thus you solve the water 
problem by making the UN stop promoting the useless poisoning nukes and 
making it illegal to go ahead with nuclear energy. Let us all resolve to
 direct all our energies(at our power peak capacity of 400000 megawatts 
of living energy, much more than that of the existing nuke capacity) to 
stop nukes and change our ways to harmonise with nature by cooperatively
 planting trees and reforesting the world without using dangerous and 
unacceptable genetically engineered trees. This is the way to survive.
