      Hmm I didn’t have any atmosphere classes for a while but let’s look at some numbers.

      So the ozone “hole” last year, according to NASA is 28.2 million km2 (bigger than USA and Canada put together)
      and the surface of Earth is 510.1 million km² (well I know that ozone layer will be a bit bigger as it’s above the planet but let’s use this number as approximation)

      so the percentage should be about…..
      28.2 / 510.1 = 5.6%
