The Big Pictures of Population Seven Billion

The United Nations Population Fund estimates that in one week, on October 31, 2011, the world's population will reach 7 billion. Just 200 years ago, there were only 1 billion people on the planet, and over the next 150 years, that number grew to 3 billion. But in the past 50 years, the global population has more than doubled, and the UN projects that it could possibly grow to 15 billion by the year 2100. As the international organization points out, this increasing rate of change brings with it enormous challenges. Meeting the basic needs of so many will mean growing, shipping, and distributing more food while providing more clean water, health care, and shelter -- all without inflicting too much further damage on our environment.

A group made up mostly of unmarried men poses for a photograph in the remote village of Siyani, about 140km (86 miles) west of Gujarat's capital of Ahmedabad, India, on October 5, 2011. Siyani is typical of many Indian villages and may be an indicator of things to come as India's male to female ratio declines. The village has some 350 unmarried men over the age of 35 - and hundreds more under 35 - because there aren't enough women to marry. Many women have also left to look elsewhere for grooms with more money and better prospects. Census data released earlier this year revealed there are 914 girls for every 1,000 boys born - a sharp fall since 2001 when the ratio was 933 girls for every 1000 boys.

Lack of a national policy on birth control and access to modern family planning methods - frowned upon by the powerful Catholic church - are some of the factors that have led to the country's population ballooning to nearly 100 million, according to various government and private sector estimates, with the Philippines the second most populous nation in the region after Indonesia.

According to a May 2007 WWF survey called "Dirty Thirty", the Greek Public Power Corporation's (PPC) power plants of Kardia and Agios Dimitrios are the EU's top two polluting stations. The once flourishing nearby villages of Charavgi and Kleitos have been gradually abandoned since PPC opened the two mines. The company "bought" the villages and relocated residents elsewhere. The only person who now lives in Kleitos is an Indian immigrant, Jangdip Pal, 45, who works as a nightguard at the mine. And only one shepherd and his family live in Charavgi. The power plants produce 70 percent of Greece's electricity.
