Many people are concerned about environmental issues. Not only the fiercest activists, but also politicians, stars, cinematographers and ordinary people periodically return to them. The most discussed phenomena in terms of environmental problems are global warming and ozone holes. Everything seems to be clear with the first one — the temperature has risen, which means warming. And what about the holes and why are they called that? Are they holes at all and where are they located? What influences them and can they be ”sewn up”? Is it true that they exist, or is it all a big hoax? As you can see, I have already asked more questions in the introduction alone than I can answer. But there are answers to some of them. If you have not thought about the need to protect the ozone layer, perhaps after reading this article you will change your mind. And at the same time you will understand that not only some mystical corporations influence its depletion, but also each of us by our actions and habits.

The ozone hole is called the local depletion of the ozone layer, which covers our planet at an altitude of about 25 kilometers. As such, there is no hole there, there is precisely depletion, a decrease in the concentration or thickness of the layer. But this is already enough to lead to unpleasant consequences in this area.
To measure the ozone layer, it is customary to use a unit of measurement called the “Dobson unit”. One such unit is equal to the ozone layer of 10 microns. The thickness of the ozone layer above the earth’s surface differs in different places, but holes are usually called those places where the ozone content drops to 220 Dobson units.
