As the trees and day lilies start blooming, it's clear Mother Nature has begun to cast her spell over the region. And with the arrival of springtime, our attention turns to the long list of tasks that make up "spring cleaning." Of course, everyone's list is different ... but how "green" is each of us committed to making our spring cleaning activities?

Here are a few common spring cleaning tasks to consider "greening" as you write up your to-do list:

1. Tune up your lawnmower and lawn equipment
Before you wheel that mower out of the shed and crank it up, remember that the engine probably has not been turned over in months. When you consider that the US Environmental Protection Agency has found a typical gas-powered mower gives off as much pollution per hour as 11 cars, it's worth getting the mower tuned up before yard season begins. New filter, oil and spark plug, plus some fuel stabilizer, and you're ready to roll. If you're in the market for a new machine, why not check out an electric mower?

2. Do a quick check around the outside of your house
Inspect your air conditioner for any obstructions around it and make sure it's in good working condition. After dark, turn on the lights inside, walk around your house and look for any gaps around windows and doors where light comes through -- a sure sign more sealant is needed.

3. Put your old PC equipment into the hands of someone who could really use it
Technology moves by in dog years, especially when it comes to personal computers. If you're getting a new CPU or monitor and planning to scrap your old equipment, don't send it to the landfill. Give your Pentium or faster computers and parallel equipment (monitors, mice, speakers, printers, modems, etc) away to ReBoot Georgia, a non-profit that refits old computers for use by persons with disabilities. Contributions to ReBoot are tax-deductible.

Oh, yeah ... one other line that should be on your to-do list: if you've changed your e-mail address in the past 6 months, make sure The Clean Air Campaign has your correct e-mail address to send out Smog Alerts so you'll know when the next day's air quality is forecasted to be unhealthy. That way, you can plan ahead for any activities you might consider doing outdoors. Simply register here.
