Human population could collapse and be cut in half in just 40 years, doomsday study reveals
A recent study suggests that the human population could be halved in the next 40 years due to various global crises. Researchers analyzed 12,000 years of population growth and warned that pandemics, wars, and climate change could lead to a rapid decline. While the findings are based on hypothetical scenarios, they highlight the potential fragility of human population dynamics.
- ▪The study predicts a potential population decline to two billion people by 2064 under severe environmental conditions.
- ▪Researchers emphasized that the findings are not a forecast but an illustrative scenario to demonstrate sensitivity to abrupt changes.
- ▪The current global population of 8.3 billion could face drastic reductions if environmental chaos intensifies.
