Population growth?

[observer]

In 1066, the UK population was around 1 - 2 million, which rose to around 6 million by the time of the Black Death, which halved it (14th C); it continued to rise, despite the losses of the Great Plague (17th C) to around 40 million by the late 19th C; continued rising (despite a 20% loss in the 1918 flue pandemic); and is estimated to reach 70 million by 2030. My point being: there has been a continual increase in population throughout history, despite everything nature has thrown at us, which presumably rises exponentially, rather than what one "expert" suggested, which was that population levels were fairly stable up until the late 1800s when vaccinations began to be introduced.
