Debunking Overpopulation: Why the World Needs More People, Not Less
Doomsday predictions about a world with too many mouths to feed, once predicted to reach 11 billion by 2050, are being drastically reevaluated.
What's the Latest Development?
Doomsday predictions about a world with too many mouths to feed, once predicted to reach 11 billion by 2050, are being drastically reevaluated. The shift comes in light of the over 80 countries that have fewer births than required to replace the number of individuals who die each year, including every country in Western Europe, China, Japan, Russia, Poland, and Canada. "Populations forecasts now assume much lower future fertility levels, but even the present consensus that world population will be about 9.5 billion by mid-century may be too high as fertility continues to fall rapidly in poorer countries."
What's the Big Idea?
Any claims about the disadvantages of an "overpopulated" world must be weighed against the advantages of large populations, according to Nobel Laureate and University of Chicago professor Gary Becker. "These benefits include a larger number of young persons who, as mentioned earlier, are more likely to innovate, such as coming up with more efficient ways to grow food, and pay for the benefits to retired men and women. A bigger population also increases the demand for new drugs, software, social networking, and other innovations that have increasing returns to the scale of demand."

These modern-day hermits can sometimes spend decades without ever leaving their apartments.
- A hikikomori is a type of person in Japan who locks themselves away in their bedrooms, sometimes for years.
- This is a relatively new phenomenon in Japan, likely due to rigid social customs and high expectations for academic and business success.
- Many believe hikikomori to be a result of how Japan interprets and handles mental health issues.
How a cataclysm worse than what killed the dinosaurs destroyed 90 percent of all life on Earth.
While the demise of the dinosaurs gets more attention as far as mass extinctions go, an even more disastrous event called "the Great Dying” or the “End-Permian Extinction” happened on Earth prior to that. Now scientists discovered how this cataclysm, which took place about 250 million years ago, managed to kill off more than 90 percent of all life on the planet.
A new study discovers the “liking gap” — the difference between how we view others we’re meeting for the first time, and the way we think they’re seeing us.
We tend to be defensive socially. When we meet new people, we’re often concerned with how we’re coming off. Our anxiety causes us to be so concerned with the impression we’re creating that we fail to notice that the same is true of the other person as well. A new study led by Erica J. Boothby, published on September 5 in Psychological Science, reveals how people tend to like us more in first encounters than we’d ever suspect.
