title: A final remark on pitfalls.
abstract: Abstract   I agree that criticism is relatively easy. Further, I should like to repeat that the contributions made by Enke and others in calculating cost-benefit estimates have been stimulating. However, at a time when the so-called 'population explosion' has become a hot topic in the mass media and elsewhere there is some danger of overselling the results. To me it seems that relatively little criticism has been ventured in the past. Of course, I cannot prove this, but I suspect that most readers have a bias (as I do) in favour of birth control, and we seldom feel compelled to ferret out definciencies in procedures that lead to results which are in accord with out tastes.
