No, I do not accept that Malthus was necessarily right, at least when it comes to human populations. We are practically unique amongst the species supported by the earth in our ability to adapt to the various ecological niches on offer, and uniquely able to dramatically effect our environment to adapt to us.
I do agree that the global human population and its exponential growth is a definite cause for concern though, purely through finding food and clean water especially for the poorer developing economies, where high infant mortality, poor or non-existent sanitation and clean water supplies and very basic educational systems are in place.
Until those more fundamental issues are addressed in such societies, you will have very little luck in persuading them to exercise birth control as practiced in the developed world and of the logic of smaller families.
