One simple solution is to use native plants in gardens.

If you live in a semi-arid environment, like most of Oz*, then perhaps your garden shouldn't look like an English lawn. Use native plants. It conserves water, it preserves native species, it creates native ecologies. It is water conservation within a larger, sustainable environment frame of mind.



* Or Arizona, Texas, Southern Europe, South Africa. Can't use your airconditioning and swimming pools either. We up north, of course, are still allowed our central heating. My sense of justice demands that people who live in the sun must pay a price for it.
