This is from Tim Roberts. I am a consultant patent attorney based in UK, formerly working for a seed company. Professor Muir makes a vital point. Birthrates in developed countries have fallen to below replacement levels. This seems to be associated with prosperity.
Prosperity comes from economic growth, which is linked to globalisation and technical advances.
Trying to make the poor richer is certainly a more acceptable option than exhorting them to have fewer children. Of course, it has one serious drawback - it is likely to make the rich richer as well. The last day for receiving messages is Sunday 17 December. No way to avoid that I suppose. My approach to these issues is that poverty is not nobel or an ideal to be sanctified, and that severe poverty is indeed a terrible thing which all the wealthy of the world are morally obliged to help resolve.
