How population explosion challenges the survival of the planet
IN THE YEAR OF SEVEN BILLION: An Interview with Andrew Revkin
Andrew Revkin's Dot Earthblog covers climate change, the environment and sustainability, and introduces itself in this way: "By 2050 or so, the human population is expected to reach nine billion, essentially adding two Chinas to the number of people alive today. Those billions will be seeking food, water and other resources on a planet where, scientists say, humans are already shaping climate and the web of life." This year the earth's population is expected to exceed 7 billion people.
