Among Peter Garrett’s tips to “protect our precious environment”:

"Have less lawn and more plants or paving - this reduces water usage."

More paving? If you say so, chief. Parking lots for Gaia! Mind you, water is useful in ways that don’t involve plants. More from Pete:

"Grow your own food - start with herbs."

Good thinking. You don’t want to start with cattle or Chilean sea bass. Start with herbs, then work your way up.
