> If that water is from rain then it's a renewable resource, and if it's not used it will just flow to the sea and be wasted. This is simply not true. A large amount of rainwater goes to (or would go to) replenishing aquifers, which we use to provide our drinking and irrigation water. Unharvested rainwater is not wasted--it replenishes our natural freshwater storage. Additionally, not all water used is captured rainwater. Some comes from those aquifers being replenished by rainwater, and some comes from fossil aquifers, which DON'T get replenished on a human timescale and are truly non-renewable. If all our livestock were grown in places like Wales, maybe the idea of "use it or lose it" holds true, but we've got a lot of cattle sitting atop the Ogallala Aquifer in the US, and you can find similar situations many places where we raise livestock.
