Oh, brother...here's pseudo-science at its best. More environmental BS suggesting that we should go back to living in mud huts or at least feel guilty that we don't. Prof. John is missing the real issue:
Forty per cent of women graduates dont have a single baby at the age of 35.
It is the uneducated who are propagating at a rate far in excess of the educated population. In the old days of the agrarian economy, children were an investment that raised family productivity. Today, children are a (very expensive) consumption item. It's not by accident that some of the highest birth rates are associated with the lowest educational rates.
Recommend that you see the “IDIOCRACY” DVD: it shows the future of the U.S. where moron voters elect bodybuilder politicians who like to show off their steroid enhanced muscles. If you live in California, don’t bother watching the movie - the future has already arrived here.
