Everything, what we learn in school, is so important. And if someone thinks that the air isn’t visible, it doesn’t mean that it doesn’t play any role for us. Of course, it is taken into account that people breathe with the help of air. But there is one more important role, which is played by this substance. What is it?
Obviously, the ozone layer, which is located between the earth and the surface of the sun, protect the humans from the light and radiation. Thanks to its existence, inhabitants of the earth are protected from the ultraviolet rays which come from the sun and have a great power. With the absence of this layer, all living creatures that live on our planet will be affected by dangerous rays.
Of course, we know that nowadays people from all countries suffer from such a disease as a cancer. But the skin cancer, as a rule, develops because of the great influence of ultraviolet rays. Scientists say that this protective layer is locates above the surface of the earth. Approximate high is fifteen – thirty kilometers above the planet. It was mentioned above about the air. And it is not just words, because the ozone is made from three atoms of oxygen. It is also known as O3. But this differs from the usual air which we always breathe in.
Being a unique substance, ozone has a strong odor. By the way, it looks like a blue air. Molecule of ozone is very are. But even the smallest amount of them can protect the people and plays the great role. While realizing this process of protection, this substance absorbs the negative substances which contain in ultraviolet. Ultraviolet light, which is known as UVB, has the most harmful radiation for living creatures. Due to this, people can suffer from the cataracts, immune system suppression, skin cancer and they also can damage to crops. The easiest influence is that UBV can proved the promote aging of skin.
Oncologists prove that one in every 5 residents of United States suffer from any type of skin cancer, which was developed with the person’s lifetime. Unfortunately, the statistics demonstrates that during every hour one American dies because of the harmful disease. Melanoma is the most dangerous type of skin cancer, which leads to the death. Such type is the most dangerous for people, but, unfortunately, it is the most popular case which doctors find while observing the patients.
In the last few years the cases of this type of cancer have been doubled. Oncologists advise to protect the skin and to stay in closed spaces, when the summer sun shines too brightly.
