long term effects
the waste products it creates and also it will cost billions of dollars, will we have enough money to continue to do this?
pros and cons on humans
to make fresh drinkable water it cost lots of money, so therefore it is expensive.
when they take all the salt and minerals out of the water they have lots of salt and minerals left over that just sit there.
pros and cons on water
when they take the salt out there is a lot of salt left behind. so what are they suppose to do with all that salt? what they do is they put it back in the water an make the water even more salty. so then when they do it again its twice as salty.
pros and cons effects on the environment
every time a gallon of water is taken in 2x the salt goes back in the water.
