In response to #1 (environmentally friendly project):
Liberty Tax Service Centers nationwide are conducting the "Cell Phones For Soldiers Drive". They set up donation boxes at each one of their locations where people can drop off their old, dead, and broken cell phones and equipment. The cell phones are then recycled into usable prepaid phones and sent to servicemen overseas.
I think this project is good for the environment because those old phones don't end up in a landfill somewhere or by the side of the road, causing clutter and litter. It's also cheaper to recycle an old phone than it is to build a new one, so this is good for the environment because we use less natural resources and create less pollution.
The biggest factor in recycling old phones is in the moral encouagement it gives the servicemen overseas as they realize we care and think about them enough to provide them with prepaid communication devices they can call home with.
