Matt Ridley observes in his excellent book The Rational Optimist:
Despite a doubling of the world population, even the raw number of people living in absolute poverty (defined as less than a 1985 dollar a day) has fallen since the 1950s, let alone the percentage living in such absolute poverty. That number is, of course, still all too horribly high, but the trend is hardly a cause for despair. The United Nations estimates that poverty was reduced more in the last 50 years than in the previous 500.
He goes on to explain that population growth has not led to the mass starvation that greenies have been predicting with monotonous regularity since the 1970s. There has been a revolution in food production that has tripled the yield of staple plants and ensured that – while there is still a long way to go – most on our wonderful planet have full bellies and increasing life expectancy.
But that doesn’t stop the BBC from trumpeting this alarmist report about starvation caused by climate change as if it were a certainty. They stick to their unquestioning acceptance of the green creed emblazoned on every BBC door: millions are going to die because of our nasty, selfish, capitalist ways. The subtext makes International Socialists look subtle. The report is from the same Doomsday script as has been rehearsed dozens of times before, based on the same flimsy models. And the reporter quotes without a trace of balance the preposterous opinion that we can limit – as if we had supernatural powers – global temperature rises as easily as switching a thermostat. Jennifer Carpenter is clearly yet another of the army BBC climate-change activists without the remotest comprehension of science or development history.
