Massive hole in ozone layer

Imagine life on Earth without the protective ozone layer in the atmosphere absorbing dangerous UV rays. Scientists predicted that this would be the scenario by 2060 if nothing was done to reduce CFC emissions. But this is a good news story: in 1987, by agreeing to implement the Montreal Protocol that limited CFC emissions, ...
