Pro-natal policies needed?

Here is a story with huge implications for the future but which few are making much of: "Canada's Birthrate Falls to Lowest Since Records Began in 1921." There are, of course, all sorts of legitimate reasons why specific couples may choose fewer children. Yet I wonder whether over the long term we will be forced to re-examine our priorities in light of the coming apparent decline in population. This may prompt a reorientation of government policies as well, particularly with respect to abortion and tax incentives encouraging larger families. We may be made to ask fundamental questions, for example, whether there is a responsibility -- and perhaps even a duty -- to produce the next generation or whether it can simply be left as a matter of personal choice and public indifference.
