The world population reached seven billion in 2011. At current growth rate, it is expected to reach eight billion by 2024 and nine billion by 2037. However, many projections predict that the world population will level off at around 9 billion individuals. Why is the world population expected to level off? Select one: a. The global fertility rate has been decreasing for the past 20 years and is expected to decline even further. b. More than a third of the world population is expected to be aged 60 years or above in 2100. c. The Earth’s carrying capacity is estimated at 9 billion individuals, when the global birth rate and death rate become equivalent. d. Recent technological and medical advances led to increased life expectancy, allowing individuals to live longer.
