That all depends on the size of the surface of the pool the amount of people going in and out of the pool etc. To see if a pool is leaking take a bucket of water out of the pool, mark the water level of the pool and the water level in the bucket. Then leave the pool and bucket alone for a day or two. If the water level in the pool has gone down more then the water level in the bucket then there is a leak or water is being removed in some way.
If the levels are the same then the water lost is a result evaporation. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
