Chemists are the specialists in chemistry, that interact with chemical properties, and reactions. The earth is made up of different gases. Some of this gases are needed for life in the planet but other gases can be harmful to the living. Gas’s use in regular quantities are favorable to the earth. The world started to become more advance and had to use more of this gases to produce everyday objects and inventions by men. Little did we knew this chemicals we going to affect us in our life. Chemist Jose Mario Molina actually discovered that chlorofluorocarbons were affecting the ozone layer.
Mario Molina was born on March 19, 1943, in Mexico City. Molina was interested in science since a very young age that he created his own and personal chemistry lab in a bathroom at his house. Molina's aunt was a chemistry and figured out her nephew’s great interest in science. She was a key figure in his life because she helped him to perform chemistry experiments that weren't taught at his school. He completed his studies in Mexico and Germany before moving to the United States to achieve an advance degree in physical chemistry.
At Berkeley University, Molina saw the connection of science on human life and society. He found that it was irrelevant the research some people were doing for the development of weapons that would not help society and other destructive purposes. Mario wanted to work on something that would benefit society. Molina wanted to made a difference and do something that helped the living not something that would destroy them. He found the interest on the chlorofluorocarbons that are used in refrigerators. In 1973, he joined with professor Sherwood Rowland to begin a research in chlorofluorocarbons. This chemicals were thought to be harmless to our environment but they were stored in the ozone layer and didn't know what happened to them.


While doing his research Molina learned that these compounds move up to the ozone and stay there. He expected the compounds to be destroy by the solar radiation. However to his surprise he formed that chlorofluorocarbons would simplify into component element when exposed to radiation. This simplify components produce a highly concentration of pure chlorine atoms. From there he already knew that the ozone layer can be destroy with chlorine.
The ozone layer is the one that protects living things from the pure ultraviolet rays of the sun.

Depletion Of The Ozone Layer Essays

- Due to human activity, our planet has been slowly depleting over the years and has been recently increasing. The problems of global warming and climate change have risen due to the carelessness of the human population. Some of the problems happening to the planet is depletion of the ozone layer, the increase of endangered animals, and a decrease of natural resources. Many people fail to realize that our species is the reason this planet is dying. Increasing populations mean a higher demand for resources which will not be here forever....   [tags: Oxygen, Carbon dioxide, Ozone depletion]

We Must Stop The Ozone Layer Essay

- Has a person ever woke up in the morning and walked outside only to find trash (i.e. a can, papers, or bags) thrown in their yard. A mess they did not make but are no responsible for cleaning up. Does not seem very fair to most people. Look at the way God may think. God looks down and sees the care his people puts into the very planet that He created for them. People burning things into the atmosphere ruining the protective ozone layer that is over the Earth. Some people do not even think that the ozone layer exists even though The United States and over 180 other countries, saw that certain chemicals were causing the layer to start breaking down....   [tags: Earth, Atmosphere, Sun, Ozone]

Ozone Depletion and Industrial Output Essay

- Ozone Depletion and Industrial Output For years, we have heard about the ozone crisis: that because of industrialization and the lack of pollution-consciousness by our industries, governments, and academia, we have put so many environmentally harmful products into the atmosphere that our ozone – the good kind, the kind that protects us from harmful UV radiation – is becoming dangerously damaged. It is becoming thinner and developing holes, like the large hole over Antarctica. Predictions made expected the ozone hole to continue to increase and for the general thickness to get continuously thinner, so that the harmful UV rays of the sun would pass right through our atmosphere an...   [tags: Ozone Layer Environmental Essays]

Essay on What´s The Ozone Layer?

- The ozone layer is a deep layer in the Earth’s stratosphere that has an altitude of about 6.2 miles and contains a high concentration of ozone molecules. The ozone layer shields the entire Earth from some of the harmful ultraviolet rays that come from the sun. The Earth’s atmosphere is composed of several layers, but the layer that we live in - the “troposphere” – is where most weather occurs. Above the troposphere is the stratosphere which is where most of the effects caused by ozone holes and global warming originate....   [tags: ultraviolet rays, ozone moleculas]

Jose Saramago's Blindness Essay

-      When defining the word blindness, it can be interpreted in various ways. Either it can be explained as sightless, or it can be carefully deciphered as having a more complex in-depth analysis. In the novel Blindness, Jose Saramago depicts and demonstrates how in an instant your right to see can be taken in an instant. However, in this novel, blindness is metaphorically related to ‘seeing’ the truth beyond our own bias opinions. Saramago’s novel clearly illustrates themes that describe the importance of the awareness of others, in terms of feeling oppressed by fear, lack of trust, dehumanization, and segregation....   [tags: Jose Saramago Essays Blindness]

The Ozone Essay

- The Ozone Ozone derives from the greek word ozein which means to smell. It was first discovered in 1839 by Christian Friedrick Schonbein who noticed it because of its distinctive acrid smell. He discovered this at the University of Basel in Switzerland. Ozone is merely oxygen, but not the type we breath. Ozone, O3 has three compounds while oxygen has only two. Ozone is reac- tive, meaning it does not stay still, and wants to go back to its original state, with two compounds, O2. This is why ozone isharmful....   [tags: Essays Papers]

Essay about Ozone

- Ozone Ozone is an important molecule in maintaining the homeostasis in the environment. Ozone, the molecule O3, makes a layer in the stratosphere, situated 10 to 15 kilometers from the earth's surface. The dioxide molecule, O2 and Oxygen atom O, collide with each other result in the formation of Ozone, O3. In this reaction, the molecule O3 contains an excess of energy. Once the molecule is formed, it is not stable enough to last long. The energy-rich O3 molecules discards the excess energy by colliding with another atom or molecule and transferring the energy in the form of heat....   [tags: essays papers]

Essay Ozone

- Ozone Ozone (O3) is a molecule consisting of three oxygen atoms, similar to the oxygen we breathe (O2), however oxygen consists of only two oxygen atoms. In the stratosphere, a region high up in the upper atmosphere, light rays are responsible for the breaking down of oxygen (O2), breathable oxygen into its two separate oxygen atoms. Lone oxygen atoms are markedly reactive. When a lone oxygen atom comes into contact with a breathable oxygen molecule (O2) it combines to form ozone (O3). The ozone layer is a small residual amount of ozone concentrated in a band in the upper atmosphere....   [tags: Ozone Layer Oxygen Environmental Essays]

Ultraviolet rays are some harmful for every single living organism on the earth. However the use of these gases, chlorofluorocarbons, caused the ozone layer to develop a hole in it and it was discovered by the British Antarctic survey. The ozone hole was located over Antarctica and its growth started to show increase of skin cancer causes.Then Molina conclude and demonstrated that ice crystals in the polar stratosphere amplified the ozone destructive capacity of chlorofluorocarbons.
The ozone layer filters all of the suns harmful ultraviolet rays, if this ozone starts to collapse then the rays can reach the earth. Exposure to the ultraviolet rays can be harmful for humans, plants and animals. For humans can get skin cancer, sunburns, premature aging of the skin, cataracts blindness and weakening the human immune system. Plants would be unable to grow and if we don't have plants we can not eat or receive oxygen from them. We will lose some biodiversity,species, in oceans, lakes and rivers.
Molina received the Nobel price for dicovering the ozone layer hole. He received this prize in chemistry for contributing to our salvation from a potential global environmental catastrophe. This hole that is harmful for every living organism on the planet. Even though technology is always inventing something new, humans need to realized that contaminating our planet can end with our lives. We should try to use our cars less, recycle, reduce the use of heating and air conditioning this can actually help to stop the ozone hole from expanding. This way we can have a healthy environment to enjoy for many years to come.
