Another sobering example of the here and now dangers of rapid population growth:

"Our own drugs had help create these superbugs. TB began to reappear in cities where only a few years before it was all but eradicated.

"In cities like London and New York, where people are crammed in living closer than ever before, the TB parasite has found its perfect breeding ground.

"Passed by coughing and sneezing, rates of TB are starting to approach epidemic proportions."

Any economy that requires constant, unrestricted growth to survive is clearly unsustainable and it appears that so are we. Nature will win one way or another, but will it be a painful and hard-fought battle or will we try to negotiate with her?
