David - Elsworth asked:

There seem to be a lot of droughts so is the world running out of water?


As we have seen in southern Europe; Greece, Turkey etc. there has been a lot of hot dry weather.  The water cycle in the world as a whole is very closed so water can't escape, so we are not going to run out of water.  It is possible that the amount of rainfall will decrease, although most predictions say that it will increase, but the areas it is falling in and the times of year it will fall are both probably going to change causing upheavals.
