Challenges loom as world population hits 7 billion

Hey Everybody,

The post of the week is already up, but I thought I would share this anyway. It relates directly to the class, possibly even what some of you are doing your research project on. Again, this is not the post of the week from the assigned group, it is an independent posting. No questions, just food for thought. Feel free to comment though if you like.

-Steve
