The hole in the ozone layer gets bigger and smaller with the seasons.
Depending upon when you take your measurements of the hole's size you can
use the data to your advantage. Along with this is a recent article that
states the the Amazon rain forest is performing better than before in
scrubbing the air even though its size has been reduced.
And who the hell said that a species has to last forever. The dinosaurs came
and went and we are better for it. Someday humnas time on this planet will
end, maybe by their own hand and maybe not.
