Title of Artwork:

protect the ozone layer



Artwork Description

It can be seen that it is not difficult for us to understand that the current climate issue is a hot news that cannot be missed for any news program. A good climate will make a good premise for everyone to do their jobs, but once nature's mother gets angry, it can only be terrible storms or floods or terrible tsunamis that pull thousands of people out. Go. And when it comes to climate, the ozone layer is indispensable and extremely important in protecting the Earth's climate. And to protect the Earth's climate, the basic thing is to protect the ozone layer. And we'll go and learn about the ozone layer and how to protect it:
What is Ozone? Ozone (O3) is an inorganic molecule with the chemical formula O3. It is a pale blue gas with a distinctive pungent odor. It is an allotrope of oxygen much less stable than the atomic form O2, which breaks down in the lower atmosphere to O2 (dioxy). Ozone is formed from dioxy by the action of ultraviolet (UV) rays and electrical discharges in the Earth's atmosphere. It is present in very low concentrations throughout the latter, with highest concentrations in the stratospheric ozone layer, which absorbs most of the Sun's ultraviolet (UV) radiation.
Causes of Ozone depletion Currently, the ozone layer is at an alarming level because of its depletion. The main causes of the depletion of the ozone layer are divided into two categories: Natural causes from the Sun, wind and the stratosphere, if changed, contribute to the depletion of the ozone layer. However, this is only a temporary effect, causing no more than 2% of the causes of the ozone layer. Movements are human activities. Specifically, the excessive release of chlorine and bromine from man-made compounds such as CFCs, halons, CH 3 CCl 3, etc. These gases are called ODS – major ozone depleting substances. As for CFCs, there was a time when people used the gas in air conditioners and refrigerators widely, and then scientists discovered that this gas is puncturing the ozone layer, especially in Antarctica to alarming levels. motion. This gas is currently prohibited from being produced or used in production activities. Conserve-energy-future says: Chlorine and bromine free radicals react with the ozone molecule and destroy their molecular structure, thereby depleting the ozone layer (1 chlorine atom can break more than 1, 00.000 ozone molecules, but 1 bromine atom is 40 times more damaging than 1 chlorine atom) Another cause of ozone depletion is air pollution. That is a significant cause not only affecting the ozone layer but also affecting human health.
Effects on humans Ozone layer depletion is the main cause of skin cancer, melanoma formation. Besides, exposure to UV rays will adversely affect, cause eye diseases Impact on flora and fauna Destruction of small organisms: Perforating the ozone layer will unbalance the flora and fauna ecosystem sea. Increased UV rays will have a serious effect on the growth of shrimp, crab, fish, etc. Reduce their fertility. For plants, we will see the damage of vegetation through factors such as growth process, nutritional composition, etc. Their ability to grow is also reduced due to this phenomenon Serious consequences of ozone layer perforation Serious consequences of ozone layer perforation Reduce air quality Reduce air quality: The depletion of the ozone layer leads to a huge amount of UV-B ultraviolet radiation reaching the ground surface, causing chemical reactions. learning from that also increases and will lead to atmospheric pollution. Solutions to reduce ozone depletion phenomenon Limit the use of nuclear energy, use ozone-depleting gases in equipment and production activities Limit the use of chemical pesticides Limit use Use personal cars Use clean, environmentally friendly products Strictly handle industrial parks and factories that emit harmful gases into the environment Educate and propagate to people to prevent bad actions from damaging floors ozone.
Depleting the ozone layer will degrade the health of human and animal bodies. It destroys the immune systems of the human body as well as animals, which means that humans and animals are more susceptible to disease. marine flora and fauna. Increased UV rays will have a serious effect on the growth of shrimp, crab, fish, etc. and also reduce their fertility. Reduces air quality: The depletion of the ozone layer will increase the amount of UV-B ultraviolet radiation reaching the ground, increasing chemical reactions that will lead to atmospheric pollution. Harm to plants and reduce crop yield Impact on materials: Ultraviolet rays will quickly reduce the life of materials, lose strength. In addition, it also contributes to the enhancement of the greenhouse effect. To prevent the depletion of the ozone layer, we needMeasures such as limiting the use of nuclear energy, strictly handling industrial parks and factories that emit harmful gases into the environment, and at the same time need to educate and propagate to everyone to prevent bad actions that cause harm to the environment. ozone depletion. Protect the ozone layer with actions you can take to protect your health and everyone else's from the adverse effects of ozone depletion.
