cell phones have gone from novelties to arguably the most central objects in our lives.
They connect us to our loved ones, enable busineses, help us behave more intelligently, and give citizens a viral voice -- especially important in countries where phones are the only real means people have to spread information.
China is the world leader in cellphone ownership, with 695.2 million phones, followed by India at 441.7 million, and the United States at 271 million.
80% percentage of teens who carry a wireless device, or 17 million, a 40% increase since 2004
57% teens who credit their mobile device with improving their life. Second only to clothing, teens say, a person's cell phone tells the most about their social status or popularity, outranking jewelry, watches and shoes
Cell phones pose a serious burden on the environment, gobbling up power and precious materials before heading to landfill.
In the developing countries where they are repurposed or dismantled, they can end up in the rivers and soil, where they help contribute to cancer, damage to the nervous system and to brain development in children.
In one study published last year, 34 recent cellphones were put through a standard E.P.A. test that simulated conditions inside a landfill. All of them leached hazardous amounts of lead -- on average, more than 17 times the federal threshold for what constitutes hazardous waste.
On top of the energy and cost associated with extracting the materials that go into a cellphone, the disposal of cellphones often leaves a toxic imprint on the environment
Phones and their batteries are getting more efficient. But charging them still sucks a lot of electricity from the grid.
