The scale of the future problem

The BBC asks

How should countries deal with falling birth rates?

However, the scale of the future problem is immense. For a country in the developed world to increase or maintain its population it needs a birth rate of 2.1 children per woman on average. This is known as the “replacement rate”.

But why the concern about falling birth rates? The economic problems they can cause are significant, as countries face the impact of both aging and declining populations, and a smaller workforce in relation to the number of pensioners.

For example – where will a nation’s economic growth come from if companies cannot recruit enough workers? And how can a smaller workforce afford to pay for the pensions of a much larger retired population? Those are questions that make government economists wince.

Yes but what about that other thing? You know the one. What about all the wildfires and droughts and floods and massive hurricanes and killer heatwaves? What about the crop failures and famines? What about the inevitable resource wars?

Does it really make sense to resist population decline when we know that the future populations are going to be dealing with all that only much worse?
