What to do with old cell phones ...

Option 1: Recycle Your Cell Phones:

• Each cell phone holds no less than 8 toxic elements—lead, cadmium, mercury,
  nickel, arsenic included– and can pollute up to 35,000 gallons of drinking water.
  
• Each year, phones are retired in enormous amounts: 500 million each
  year, 10 million each month.
  But what happens to the old ones? You really have three choices:
  1)Throw them away (which is bad for the environment).
  2) Put them in your sock drawer, or
  3) RECYCLE THEM!

Currently, less than 4% of those 500 million retired cell phones are recycled.
Do something to help the environment and global poverty:

to stop Niagara Falls for 72 years) and allow 100,000 women to rise from poverty through microfinance (enough to fill the brand new Dallas Cowboys Stadium).” Recycle to Eradicate Poverty Director, Brian Weinberg

Option 2: Give them away:

In addition, you can "recycle" your old cell phone by donating it to a local women's shelter. Follow this link http://www.911cellphonebank.com/drop-off-locations.asp?State=TX and type in your city and zip code to find the nearest drop-off location.
