The passage discusses the rapid growth of the world's population over time. It notes that in 10,000 BC there were only 10 million people, but that the population grew exponentially in subsequent years. By AD 1 there were 300 million people, and it took 1,750 years for the population to reach 650 million. However, in just 100 years between 1750 and 1850, the population more than doubled to over 2.5 billion. The passage predicts that the world's population will surpass 7 billion people by the year 2015. It suggests that some scientists are concerned that the rapid population increase may strain the Earth's limited resources.
