As more and more pollution occurs it can cause the ozone layer to slowly start to decay in a way as the sphere get thinner. What this impacts is the troposphere. Since the ozone layer starts to fade away it can't filter out as much harsh rays from the sun. Those rays eventually get to the earth's surface and bounces off the surface warming up the earth causing life to be affected in the troposphere by warming up the earth.
