Water is entirely unlike oil, in that it's renewable. (You might have noticed that it falls out of the sky every now and then.) Whatever water you use in 2008

Water is entirely unlike oil, in that it's renewable. (You might have noticed that it falls out of the sky every now and then.)
Whatever water you use in 2008 will still be available for use in 2020. Dams are already built and are collecting water whether you use it or not, so unless the water levels in your local dam are getting low there's no point in conserving it.
- jcl 18y agoWhile water is renewable, there is a limited supply of cheap water for crops, and some areas are using it at a higher rate than it is being replenished. Wikipedia mentions that the Ogallala Aquifer, which is used to irrigate a significant portion of Midwest farmland, may run dry in 25 years: http://en.wikipedia.org/wiki/Ogallala_Aquifer http://en.wikipedia.org/wiki/Ogallala_Aquifer For the people in that area, the aquifer is their "local dam" and it is getting low.
- hugh 18y agoThat's true. My comments don't apply if you're in an area which uses underground water.
- ars 18y agoAs you mentioned in a later post underground water is not renewable, and about half the US uses underground water (pretty much all the western half of the US). Only communities nears rivers use renewable water.
