Well, a lot of action was taken, and a lot of stuff was cleaned up. Was the case overstated? It's possible, but we don't know. We've expanded our food producing capabilities greatly, so the "Population Bomb" stuff seems a bit off base. However, that food production requires a great deal of petroleum and other energy to support, and it's not clear how long we can sustain it.

We have a lot more people now than we did in 1970, and a lot of the problems that come from overcrowding and competition for resources are starting to appear. However skeptical one might be of the latest doomesday prophecies, it would be foolish not to take these issues seriously.
