Lots of global problems seem intractable, but there’s a formula for success that we can follow.
To learn more about this topic, start your googling with these keywords:
Ozone layer: A thin layer of ozone concentrated in the Earth’s stratosphere roughly 10 kilometers above that absorbs most of the sun’s ultraviolet radiation before it hits the Earth’s surface.
Ultraviolet radiation: Invisible rays of energy that come from the sun that can be harmful to humans and other lifeforms.
Chlorofluorocarbons: Also known as CFCs, these long man-made molecules used to be widely used refrigerants and solvents before it was discovered that – when exposed to ultraviolet radiation – their chlorine atoms would break off and combine with ozone molecules.
Smallpox: A virus that killed more than half a billion humans before being eradicated in 1980.
Disease Surveillance: A practice by which disease progressions are closely monitored in order to minimize the harm caused by outbreaks.
