9 Billion Reasons to Addressthe World's Energy Challenge Now
Today, our world reached a significant milestone: Somewhere-most likely here in Asia-a mother gave birth to Earth's 7 billionth inhabitant.
Of course, we'll never know for sure who the 7 billionth person is. We'll never know exactly where he or she was born. But based on computer projections from the United Nations, today is that child's birthday.
And a true milestone it is, one that reinforces why the world must address its future energy needs now. As a result of longer life expectancy and high birth rates in some ofour most populous countries, five more people are added to the global population every second. Within the next minute, there will be nearly 300 more.
At that rate, Earth will be home to more than 9 billion people by 2050.
