Whether you're reading this article on a desktop computer or a mobile device, you're most likely producing greenhouse gas emissions that contribute to climate change. That's not to say you should stop using all the fun and convenient gadgets of the modern era, but there are a few things you can do to control your carbon footprint.

Dell's Plant a Tree program offers one such opportunity, replacing thousands of greenhouse gas-absorbing trees in formerly forested areas around the world.

Dell has teamed up with The Conservation Fund and Carbonfund.org, planting more than 258,000 trees since 2007. But they're not done yet — Dell and its partners hope to plant half a million trees by 2012.

The Plant a Tree program identifies and secures areas that were once lush and green but are now in need of conservation and restoration. These locations not only absorb tons of greenhouse gases, but also improve air quality and create a safe haven for wildlife.

So far, the Plant a Tree program has project sites in the U.S., Canada and Central America, including the Tensas River Reforestation Project in northeastern Louisiana.

Once a crucial habitat for hundreds of wildlife species such as the Louisiana black bear and the Florida panther, this area will eventually be restored to 2,000 acres of native forest which will eventually absorb 450,000 metric tons of CO2.

Whether you own a Dell computer or not, you can offset some of your own emissions and help this program continue by making a donation at the Dell website.

Amounts range from $2 to offset a laptop up to $40 to offset a server. Dell also makes it easy to donate when making a purchase.
