How to Solve Thorny Global Problems

posted by Jason Kottke   Sep 22, 2021

Within the past 50 years, the global community has solved two huge problems that had the potential to harm every person on Earth. Smallpox once killed 30% of the people who contracted the disease but through the invention of an effective, safe vaccine and an intense effort that began in the 1960s, smallpox was completely eradicated by 1980. In the 1980s, scientists discovered a hole in the ozone layer that protects the Earth from UV radiation; further depletion would have caused major problems with the world’s food supply and an epidemic of skin cancer. Forty years later, we’ve virtually eliminated the chemicals causing the depletion and ozone losses have stabilized and have recently shown improvement.

So how did we do it? The short video above talks through each of challenges, how they were met (science + politics + a bit of luck), and how we might apply these lessons to the big problems of today (climate emergency, the pandemic).
