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, the world chose a different future. Watch as scientists show how the ozone hole was discovered and listen as they describe how a serious challenge to life on Earth was averted.
