BBC report: First world countries must respond to crash in fertility by totally opening their borders to unlimited mass migration
Falling fertility rates are “a success story” because they mean more women are in work and are not having children, according to a report by the BBC published on Wednesday.
Lower fertility rates will result in 23 countries, including Spain and Japan, seeing their populations drop by more than half by 2100, Professor Christopher Murray told the BBC.
“That’s a pretty big thing; most of the world is transitioning into natural population decline,” the researcher said, adding: “I think it’s incredibly hard to think this through and recognise how big a thing this is; it’s extraordinary, we’ll have to reorganise societies.”
“You might think this is great for the environment. A smaller population would reduce carbon emissions as well as deforestation for farmland,” says the BBC, which has been promoting a “child-free” life to British women for decades as “liberation” and as a means to “save the planet”.
“Countries, including the UK, have used migration to boost their population and compensate for falling fertility rates,” says the BBC.
Prof Stein Emil Vollset said: "Responding to population decline is likely to become an overriding policy concern in many nations, but must not compromise efforts to enhance women's reproductive health or progress on women's rights."
Meanwhile, the population of sub-Saharan Africa is expected to treble in size to more than three billion people by 2100.
And the study says Nigeria will become the world's second biggest country, with a population of 791 million.
Prof Ibrahim Abubakar, University College London (UCL), said: "If these predictions are even half accurate, migration will become a necessity for all nations and not an option.
"To be successful we need a fundamental rethink of global politics.
"The distribution of working-age populations will be crucial to whether humanity prospers or withers."
