Yes you do. It is an important environmental issue.
You need to be worried. It is because ozone hole could cause fatal UV to enter the earth.
That is why the ozone layer is having problems. We need to STOP adding things to the atmosphere that Nature does not immediately accept as "coin".See "Can the hole in the Ozone layer be fixed?"
Ozone layer is depleting. We need to protect it.
We need to be worried as it causes UV to come it. And as we know UV is very dangerous.
The ozone layer does not need to be disrupted. It protects us.
Yes,we need to preserve ozone. It is a vital layer for life on earth.
We need to protect the ozone layer before anything else. It is because it is very vital.
You cannot be stuck in ozone. So there is no need to get out.
The ozone hole is a natural occurrence. You cannot prevent it. You might keep it from starting sooner, have more ozone in it, or from lasting longer.... but you cannot stop it from forming once a year at each pole when it is late winter / early spring there.
The lowest year-round "total column ozone" levels are at the equator. Depletion affects the entire atmosphere. Ozone holes at the pole do not put people at risk of cancer, cataracts, and ultimately starvation, since the hole heals shut when there is no sunlight with UV-B to be protected from. The ozone hole is just a symptom of other problems with the ozone layer.
Yes, we need to check the depletion of ozone layer. It is because this layer protects us from the harmful UV radiations of the sun.
