Twenty years ago, "50 Simple Things You Can Do to Save the Earth" became a best-seller.
This month - just in time for Earth Day tomorrow - an updated version of that classic text on green living is being released.
It's published by Hyperion and sells for $12.95.
Written by John Javna with his teenage children Sophie and Jessie, the revised version suggests ways to preserve the environment, including many money-saving tips.
Here are tips for conserving water and gas, as gathered by the Javnas and other sources:
Create a rain barrel. Water from your roof can be collected and then used to water the lawn or garden. Building instructions and details can be found at www.waterkeeper.org.
Garden with a green thumb. Select drought-tolerant plants for your garden. When you do water, use soaker hoses and drip irrigation systems. Spread mulch to help roots retain moisture.
Stop leaks. A single leaky faucet - with one drop of water per second - translates into 192 wasted gallons per month.
Safeguard water pipes. Popular drain cleaners can damage household pipes.
Here's a recipe for a gentle alternative: Mix one cup of baking soda and one cup of vinegar into a pot of boiling water. Pour this mixture down the drain to dissolve most clots.
Replace chlorine cleansers, which are not biodegradable, with eco-friendly alternatives such as oxygen or hydrogen peroxide-based bleaches.
Demand gas-efficient rental cars. Your selection will have a long-term impact on the auto industry, which studies rental trends when developing cars.
Low pressure in your tires sharply reduces your gas mileage. Make sure your car tires are inflated to the upper range of the recommended pressure.
Mulch more and rake less. Unless you have a heavy accumulation of autumn leaves, mulching them with your mower rather than raking them helps "feed" your lawn.
