It is common to hear things like it takes one gallon of water to create a single almond, or watering a lawn can take X gallons per month/year, or it takes X gallons to make one pound of beef or yield X pounds of alfalfa.
My question is, is that water “gone forever”? Or does the water thats used return to the water table/cycle in some other form. When you water the lawn does a large amount of that seep into the ground, evaporate, and return to the atmosphere?
Or is the water used in these ways truly gone forever (in terms of humans being able to use it again)?
Another factor to add to these answers: if the water has been treated (if it’s mains water), then a not inconsiderable amount of electricity (and so carbon emissions) will have been used to treat it, and probably quite a lot more electricity will have been used to pump it around the country. So using water is also burning energy
