The ozone layer was formed 460 million years ago. Thanks to the union of oxygen and solar radiation, the layer covering the entire globe appeared. Shortly after its creation, it took about 120 years to be thick enough to stop the sun’s rays and allow life on earth to begin.
It is important to take these data into account to know the importance of keeping the ozone layer in good condition.
There is hope of repairing damage to the ozone layer
Since technological advances began to improve the lifestyles of human beings. At the same time they were becoming the main cause of climate change. At first we didn’t realize it. But over the years the ecosystems began to be damaged by the emission of a large amount of greenhouse gases that gradually penetrated the ozone layer.
This deterioration of the ozone layer was one of the first consequences of environmental pollution. This brought warming of the ocean and alteration of wild ecosystems. However, the end of the last century and the beginning of the 21st century have been marked. In part, by a growing determination to find an effective solution to this problem that concerns us all equally.
One of the first measures suggested by the experts on the subject was to ban the production of raw materials with chemical ingredients such as chlorofluorocarbons, CFCs and others. Only with this restriction was it possible to recover 20% of the ozone layer since 2005. The data are very accurate, since NASA assigned a satellite to monitor this invisible mantle.
Researchers Feel More Optimistic About Ozone Layer Repair
Scientists are betting that the levels of chlorine in the sea and in the air will continue to decline. The result is that the ozone layer is no longer depleted. Part of this claim arose after they carried out exact studies inside the hole of the layer. Once they studied the chemical composition of the same they could verify that this was reduced thanks to the elimination of the CFC in the factories.
Part of the rush to repair the hole in the ozone layer is because the larger the hole, the more exposed Antarctica is. The studies carried out from 2005 to 2016 resulted in data that proved what they suspected. The less chlorine there is in the environment, the more likely it is that the opening will close more quickly.
Another important discovery that can be rescued is the fact that chlorine when destroyed tends to react with methane. Thus becoming a hydrochloric acid that is a gas that can be studied. This is how they managed to find the cause of the deterioration of the ozone layer.
