The ozone layer can be defined as a layer that is a major and essential part of the Earth's atmosphere. This part contains the gas known as ozone gas. This layer is located at the bottom of the stratosphere and is also one of the layers of the atmosphere.
The ozone layer was discovered by Henry Boisson and Charles Fabry. They discovered this layer in 1908 and were able to find out more about this layer by inventing a device capable of detecting and measuring the presence of ozone gas in the stratosphere.

By ultraviolet light, oxygen gas is converted to ozone gas, where it is released from the sun and has a direct and effective effect on this layer of the atmosphere. One of the most important benefits of this layer for humans and living organisms on Earth is that they prevent ultraviolet radiation from reaching the surface of the earth.

In the eighth and ninth (August and September) of each year, this hole appears above the Antarctic, which begins to widen during the autumn months until this hole disappears in November. Despite the seasonal appearance of this hole, which appears during a specific period of each year, but the problem is that this hole is increasing in size and magnitude once in a time, which suggests that significant damage in the future. The main reason for this dangerous hole is the extreme human abuse of the environment as a result of excessive selfishness, wrong industrial policies, and many other things that come from human misjudgment.
