A fascinating (though long) article on the massive global decline in fertility rates.
A couple interesting facts from the article:
1. Mexico will be older than the US by 2050
2. In addition the worlds overall fertility rate may be below the replacement level by that point.
3. Japan's population peaked in 2005 and is about to crash.
4. The greatest recent fertility declinces have been in the Middle East (I found this very surprising)

How populations cope with ever smaller workforces and ever greater numbers of elderly will

Beijing's Science and Technology Department has been experimenting with hormone therapy and crossbreeding to produce flowers that can withstand a Beijing August. "I'm sure that during those three weeks it will be crystal-clear in Beijing," energy analyst Brock says. "They're playing with all sorts of things."

Ah well, at least we're starting to see something...
