Imagine a canal which is 3 feet wide at the minimum. It contains a constant volume of water. This canal ultimately waters farm land. By way of example, California has the imperial valley which contains these canal systems. They feed desert farm land. The problem is these canals are often:
Water rights have perverted water usage. People take cheap water which was grandfathered in by old laws and agreements and they waste it to evaporation. If you think "well the water isn't lost, just evaporated, right?" You'd be close, but slightly off the mark. The water is evaporated but it's transported often hundreds or thousands of miles from its original source. We are basically bleeding rivers to feed a desert. And deserts might as well be an infinite sink for water.
We should not have farm land in deserts. But if we do, we should at least conserve the water we are using. Just because it's cheap doesn't mean it's good (not that you're implying that, just saying).
This guy has never been to the Phoenix area :P we even have rivers with no water, too! Bring the whole family, camp out and have imaginary marco / polo by the hill infested with scorpions, only a half-mile from the city dump! Bring your RV so you can feel like a complete moron with the other people who thought it was a great idea to buy a mini house on wheels that gets 6 miles to the gallon. And if you are early to rise, you can make Laughlin a day-trip to lose all your social security check by dusk, before sauntering back to the depression-rut of a life you have carved out for yourself. Because living in a desert with a large elderly population, just-barely-enough power during the summer even though there is a fucking nuclear power plant 20 miles out of town, and has been in a drought for my entire life while everyone waters their lawn 3 times a week, never felt so good!
Oh sorry I got mixed up with my "fuck off and stop moving here" speech. Give me 10 minutes.
I've been to Phoenix and I agree. I don't understand why they waste so much water.
Wouldn't that make it an aqueduct?
