Environmental problems

Great ¡¡

congratulations,

The thawing of Poles and the desertification of many areas are two of the numerous consequences of the ozone layer deterioration. As a matter of fact, the ozone layer is dedicated to protect the planet from ultraviolet radiation of the sun and ( or thus enables) enable life on earth. This natural barrier is supposed to be able to stop almost all the UVC, which are the most dangerous ultraviolet radiation emitted by the sun.
Today, no one can say that he is unaware of the danger which threatens this protective layer. It has thinned dangerously in the Northern Hemisphere during the past 40 years and its current level isn’t enough to ensure the full protection of life on Earth. There are many disastrous impacts on living organisms, (caused by )due to the growing intensity of radiation.
The degradation of the ozone layer means less filtration of the most harmful ultraviolet rays, and elevated risks for terrestrial life. Negative effects are numerous on the environment, the climate and human beings’ Health. Scientists have observed a reduction in photosynthesis which has harmful consequences on yields and crop quality, the reduction of plankton’s population in some areas, which threatens the balance of aquatic food chain. There are also more and more consequences on human beings’ health, such as superficial burns in some mountainous areas, conjunctivitis, cataracts, cancer of skin or immune system diseases.
It is not sufficient to become alarmed in front of this dramatical inventory. The problem is real and clearly identified and it is time to act to protect the hope and the quality of life of the future generations.

Wow.:D One can laern a bit from your writting.:D

The thawing of Poles and the desertization of many areas are two of the numerous consequences of the ozone layer deterioration. As a matter of fact, the ozone layer is essential to protect the planet from ultraviolet radiation of the sun and enable life on earth.

Great job!:)

The thawing of the Poles and the desertification (either this or"desertization" is correct, but in the USA we use it as you wrote)  of many areas are two of the numerous consequences of the ozone layer deterioration. As a matter of fact, the ozone layer is dedicated to protects* the planet from ultraviolet radiation of the sun and enables life on earth. This natural barrier is supposed to be able to stop almost all the UVC, which are is the most dangerous ultraviolet radiation emitted by the sun.

* when you use "dedicated to" it implies some human or divine intent of an unintelligent object.  I don't think you intend that meaning.

Excellent work, as usual!
