Earth's Real Problem: Future Underpopulation
Having hit the human population milestone of seven billion, the future we now need to face is not one of too much population growth, but too little, says strategist Sanjeev Sanyal.
What's the Latest Development?
Amid the reflection provoked by the human population milestone of seven billion, Deutsche Bank’s Global Strategist Sanjeev Sanyal says the future will not be one of too much population growth, but too little. U.N. forecasts that world population will rise to 9.3 billion in 2050 and surpass 10 billion by the end of this century misrepresent underlying demographic dynamics, he warns.
What's the Big Idea?
In fact, it is likely that world population will peak at nine billion in the 2050’s, a half-century sooner than generally anticipated, followed by a sharp decline. "One could argue that this is a good thing, in view of the planet’s limited carrying capacity. But, when demographic dynamics turn, the world will have to confront a different set of problems." Fertility rates are plunging in most countries, one of the shifts with big implications for global labor supply.
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
- In some fundamental ways, humans haven't changed all that much since the days when we were sitting around communal fires, telling tales.
- Although we don't always recognize them as such, stories, symbols, and rituals still have tremendous, primal power to move us and shape our lives.
- This is no less true in the workplace than it is in our personal lives.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
- Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
- A scientist has built a black hole analogue based on sound instead of light.
- The word "creative" is sometimes waved around like a badge of honor. We speak of creativity in hushed tones, as the special province of the "talented". In reality, the creative process is messy, open, and vulnerable.
- For this reason, creativity is often at its best in a group setting like brainstorming. But in order to work, the group creative process needs to be led by someone who understands it.
- This sense of deep trust—that no idea is too silly, that every creative impulse is worth voicing and considering—is essential to producing great work.
