Ozone screen or ozone layer?

Never had I given much thought to the terminology of these things. Through this exercise, I realised the features of this ozone concentrated zone in the stratosphere.

Also, the problem of the ozone hole is often simplified and misunderstood as one that can be solved by sending large amounts of ozone into the stratosphere. However, this may be do more harm than intended. Like what was mentioned in the lecture, this will cause the equilibrium to shift, causing even more ozone to be depleted.
