Your hobby isn't so kind to the environment. With high-end graphics cards, multiple hard drives, and mammoth LCD monitors, your computer can require as much as 750 watts -- or more. And that's just while the thing still works: Every day in the U.S., an estimated 133,000 computers are discarded instead of reused or recycled. As those computers degrade over time, they can leach toxic chemicals like lead, mercury, cadmium, and brominated flame retardants into the soil and groundwater. What's an eco-conscious gamer to do? 1UP suggests some easy, pain-free ways to take action without sacrificing your gaming rig.
