Sure, 70% of the earths surface is water. 97.5% being salt water and 2.5% being fresh water. You can't use sea water to irrigate agriculture. You can't drink sea water from the faucet. Additional money/ cost and work would be need to make the water drinkable. Please consider that many states like California, Nevada, Arizona, Texas, water is a valuable resource. And yes, we are running out of cheap drinkable water. That's why most of the west coast gets most of their water all the way from Colorado.
