Even living in the desert would cause more harm by being circumsised.
The foreskin, protects the glans from infection and microbes/bacteria.
You can roll it back, to clean it, with your fingers and/or water etc etc...
It also gives more sexual pleasure...
Jews and Muslims circumsise for ritualistic reasons, and defy all logic for the favours of the foreskin.
You should research, and see how easily the arguement for the skin is top rated.
On top, many American men are now growing back artificial skin, due to being circumsised, and more and more are saying no no to circumsision.
