I am delighted to see Angelinos taking water conservation seriously since so much of their water comes from diverting water from the deserts in Arizona, where I live. We take water conservation seriously here. The landscaping around my house is mostly rocks and sand (which means I never have to mow grass!), and the plants are mostly cactus and palm trees which seldom need watering. For those plants which we do water, we have a rainwater collection system. But the biggest thing we do for water conservation is stick to a vegetarian diet, since raising livestock consumes great quantities of water.
I have mixed feelings about desalinization using current technology, but the objection that this will upset the salinity level in the sea seems poorly thought out. Remember, all the fresh water in the world comes from natural desalinization which uses solar power, and the increment human civilization would need to supplement natural sources should be insignificant compared to this. My main objection to current technology of desalinization is that it would demand energy from current sources which also demand fresh water. Current solar power technology is too expensive to desalinate water on the scale needed to provide much of the water for a city the size of Los Angeles, but new technology should soon be able to make it affordable. I just hope that Angelinos can come to appreciate my dismay at the current situation where a city on the shores of the world's largest body of water is taking much of its water from a desert, and thus will come to support sustainable desalinization of sea water for their needs.
