In 2009, the U.S. Congress passed a five-year, $7.5 billion aid package for a country it had all but abandoned just 10 years earlier. Indeed, if one word can summarize the U.S. relationship with Pakistan, “volatile” might be it.

But they’re not as straightforward as they appear. Demographers often base their estimates on complicated assumptions that aren’t obvious to the end user.

“There is no magic bullet or solution to resolving climate change quickly,” said the Population Reference Bureau’s Jason Bremner at the Wilson Center on October 28. “Our next 100 years will be far different from the last 100 or the last 1000…and it has become clear that nations will have to pursue many strategies in order to reduce emissions, build resilience, and adapt.” [Video Below]

In his 2007 best-seller, The World Without Us, Alan Weisman explored what would happen to the planet if the human race suddenly vanished – the gradual deterioration of the built environment, the geologic fossilization of our everyday stuff, and the ecological processes that would rebound and thrive without continual and growing human pressure. [Video Below]
