That makes sense on the object level (although I was more interested in the meta, as in how to think beyond econ 101, beyond the supply-demand curve).
I should add that there are grass fields here (Vienna, Austria) that nobody waters and they are green enough - granted, there is far more natural precipitation than in California, granted, they don't look as nice as really "manicured" lawns, but they still look kinda grassy enough. The point is - probably it would be possible to find a different species of lawn grass that looks 80% as good but takes like 30% of the water. I suspect British lawn species may have been imported to Cali and that may not be such a good idea.

Good news - such a species does exist! It's called "Astroturf", and it requires even less than 30%.
I think we need a discussion thread for the californian drought going on. I would like to compile information in the main post and would like help compiling it. If we really are proud to be effective altruists then this is an area we should really figure out.
Any one have any good ideas on how we can help?
