What is happening with the global population?

• A. Decreasing due to lower birth rates.
• B. Increasing like crazy, with concerns about resources and aging population.
• C. Stabilizing at current numbers without major changes.
• D. Increasing only in developing countries.

Answer: (B)

Global population is still rising overall. Even where birth rates have fallen in many places, the total number of people keeps increasing because a large base of young people is entering reproductive age, creating momentum for more births. At the same time, people are living longer, so the world is developing an older age structure—more aging populations. This combination brings clear concerns about resources like food, water, energy, housing, and healthcare, as well as the systems needed to support a growing and aging population. So this option best matches the real trend: growth with notable worries about resources and the aging population. The other statements don’t fit as well because births aren’t falling everywhere enough to stop global growth, the total population isn’t expected to stay exactly the same, and growth is not limited to developing countries—immigration and aging in developed regions also shape global numbers.
