OK, let's be realistic. Throwing away the car keys might not work in every family. (Not to mention the fact that you're just adding those keys to the landfill.) But most of us do know that there are some simple ways to cut down on our gas use. Have your kids pick out four places within a mile that you occasionally drive to. Make a pact that you'll all try to only walk to those places from now on, as much as you can. Drive the kids to school? Ask other parents in your neighborhood if they'd like to set up a carpool system to cut down on traffic.
But let's not blame our gas-guzzling on the children. It's adults who are the ones that need to curb their fuel use. So what can adults do? Of course, make full use of public transportation, and take advantage of your own carpools. And while it's understandable that not everybody can do it, do consider walking or biking on short trips. Think about it as both saving money on gas, and investing in your overall health--which might save you future healthcare costs.
Speaking of health, being green is a great, inexpensive way to treat your family's bodies better. Read on for more tips about how responsible eating saves money.
