How many times have we heard it? Three quarters of Earth’s surface is covered in water.
The bottom line is – it is impossible to run out of water. As quickly as we drink it, we release it back into the system through perspiration, exhaling, urination, etc. The sooner wastewater makes it out the ocean, the sooner nature can turn it back into drinkable water.
Now, to be sure, the easiest and most inexpensive way to get water would be to divert it from a river and use mostly gravity to get it to where it is needed with minimal pumping. Wells are right behind that. Then comes things like aqueducts (usually requiring much pumping), reclamation, and desalinization.
People freak out about reclamation as “toilet to tap”, but I wonder what these people think is going on in rivers, with all of the dirt and animals. Nobody is stopping bears from crapping in our rivers. Modern and complete reclamation puts water through the steps nature does (through evaporation and precipitation), only faster and within our possession. But it does take energy.
In the greater Los Angles area, we are constantly told to conserve water, and that we need to find ways to cut back on water usage. We’re constantly reminded that we “live in a desert”. Yes, we know. That’s why people paid big bucks to build aqueducts from northern California, from the Colorado River, etc. We don’t just sit around and dehydrate and come up with a "cap and trade" system (like the socialists do) – we move water from one place to another for our convenience.
Ah, but we can create shortages for ourselves. For example, a judge ruled that we couldn’t get as much of our water from northern California because it was, according to someone, hurting a fish. Neglecting to build or maintain waterworks systems will also result in shortages, especially if we allow unregulated hordes of illegal aliens into the area.
But nothing has changed in nature. Nature is still cleaning water. It’s not disappearing into a wormhole, as far as we know. It is up to get the water and use it. We can't run out of water. We can only fail to drink it.
