"Today, you are one of 7 billion people on Earth. This historic milestone is rekindling age-old debates over birth control, protecting natural resources and reducing consumption. It also has many wondering whether the Earth can support so many people. About half were added just in the past 40 years, and 3 billion more are expected by 2100." (10/30/11)
