BlackTom AI · Accepted Answer

When evaluating statements about current population trends, it's helpful to compare each option to what demographic data and projections actually suggest.
Option 1: 'go extinct within 20 years.' This is implausible given the extensive historical record of long-term human survival, and no credible demographic projection supports imminent extinction within two decades.
Option 2: 'continue to grow exponentially.' While population growth has slowed in many regions, the global population is not expected to grow exponentially indefinitely. Demographic transitions, aging, and varying fertility rates lead to slower growth or stabilization rather than unchecked exponential rise.
Option 3: 'remain constant to the current population of around 8 billion people.' A perfectly constant global population is highly unlikely over the coming decades due to ongoing changes in birth rates, mortality, and migration. Projections suggest change is more gradual and directional than perfectly flat.
Option 4: 'hit a maximum around 10 billion people.' This aligns with many widely cited projections from demographic research that estimate a peak near 10 billion later this century, followed by stabilization or very slow decline depending on fertility, mortality, and migration patterns. Therefore, this option best matches the mainstream expectation based on current trends.
In summary, the main competing ideas are rapid extinction, unwavering exponential growth, or a perfectly flat 8-billion figure, none of which match the observed slowing growth and finite carrying-capacity considerations. The commonly cited projection around 10 billion reflects the balance of expected births and deaths as societies develop and fertility rates converge toward replacement level.
