What We Now Call The Ozone Layer

The ozone layer is a naturally occurring gas that acts like a blanket filtering out the Suns UV radiation. The ozone layer has a hole in it which allows UV radiation to reach the earth's surface. Causing skin cancer, cataracts, and weaker immune systems. The hole in the ozone layer is caused by chlorofluorocarbons. Commonly found in aerosols, refrigerators, air conditioners and cars. In the documentary An inconvenient truth, Al Gore stated that they fix the hole in the ozone layer.

The third factor that plays a major role in causing skin cancer is the Ozone layer. It helps protect people from ultraviolet radiation. However, the ozone layer is shrinking and this is due to man-made products like sprays and combustion of cars that are emitted in the atmosphere. This process is allowing more ultraviolet penetration to the earth thus increasing risk of skin cancer (Bair, 1991, P. 367,368). Ultraviolet radiation are the chief causes for skin cancer because the UV radiation

The ozone is a form of oxygen that combines three oxygen atoms in each molecule. Its important because its like a filter. CFCS, also known as, chlorofluorocarbons are used to break up some of the ozone molecules

Did you know that with all this talk about global warming, and the disappearing of the ozone layer, the root of the problem is us? Yes, we’re the cause of all those problems. We keep putting something called greenhouse gases into the air. A few greenhouse gases are water vapor, carbon dioxide, and methane. While some climate change is natural, humans need to be careful about greenhouse gases because ecosystems are changing, sea levels are rising, and global average temperature increased by more than 1.3 degrees Fahrenheit over the last century.

The stratosphere absorbs the UV radiations. The troposphere is the lowest part of Earth’s atmosphere.

Not many people know what global warming or the ozone layer actually is. The ozone layer is a layer in the earth 's stratosphere that absorbs most of the ultra violet rays from the sun. Global warming is the progressive optimization in the overall temperature of the earth 's atmosphere. Carbon dioxide levels have a major effect on the earth’s overall temperature. For 650,000 years the carbon level has fluctuated between 160 and 300 parts per million. 1950 to 2014 is when it immediately skyrocketed to 400 and continues to increase today . About thirty years ago scientists unearthed a hole in the ozone layer. The ozone layer hole is not a complete hole

In 1988, the National Aeronautics and Space Administration had conclusive proof products adding to the output of carbon dioxide and methane gases in the atmosphere were causing the earth to warm; and, if not stopped will make it inhabitable for human life. In the 1970’s the United States had conclusive proof that products releasing Chlorofluorocarbons into the atmosphere were causing the ozone layer to deplete; and, that if continued would be dangerous for human life. The United States took international global action, by joining the Montreal Protocol, to phase out the products producing chlorofluorocarbon and the ozone layer has been successfully replenished .

The fact that it is extremely stable makes it possible for CFC to slowly make it way up into the stratosphere. This prolonged life in the atmosphere allows CFC to reach great altitudes where photons are more energetic. When the CFCs come into contact with these high energy photons, their individual components are freed from the whole. Because Chlorine acts as a catalyst it is able to destroy so much of the ozone layer Chlorine then initiates the breakdown of ozone and combines with a freed oxygen to create two oxygen molecules.After the reaction, chlorine will be able to begins the cycle over and over again with another ozone molecule. With this reaction, chlorine is able to destroy thousand of ozone layer. Because the ozone molecules are being broken down they are unable to absorb any ultraviolet light so we experience more intense UV radiation at the earth's

Ultraviolet radiation is invisible rays that are part of the energy that comes from the sun. For example; Ultraviolet radiation can burn the skin, such as a sunburn and cause skin cancer (Medicinenet). The ozone layer is a layer of ozone (a colorless unstable toxic gas) in the upper atmosphere that prevents dangerous radiation from the Sun from reaching the surface of the Earth (Merriam-Webster). In correlation of the two together, we need the ozone layer to protect or animals and our plants from the ultraviolet radiation. Without the ozone layer being there it could damage the immune system to animals and humans, leaving many with skin cancer and eye cataracts (eco-action). The ozone layer is also important because it will have a negative

Bromide ions are released from methyl bromide when the sun’s UV light hits volatile methyl bromide in the air. A bromide’s strong pull breaks bonds between ozone (O3) and gains a single bond with oxygen. In the reaction between methyl bromide and ozone, bromide catalyzes ozone’s destruction by stealing single oxygen atoms, preventing ozone from reforming. A healthy ozone layer rebuilds itself by bonding oxygen molecules to single oxygens to form ozone; however, methyl bromide prevents this process from occurring.13

My first reason is because of a chemical called chlorofluorocarbons (CFCs). It has a tendency to drift up to the layer of ozone gas that surrounds the Earth and break up the ozone molecules. CFCs were found in aerosol cans that sprayed substances like deodorant and hairspray and in refrigerants, fire extinguishers and solvents for cleaning. Other ozone depleting chemicals were found

Scientist 3: The ozone layer protects us from the sun's UV rays. If it weakens, people will get skin cancer, cataracts, and their immune systems will weaken

Why is the ozone layer of much concern to scientists and environmentalists? The ozone layer is quite beneficial to human life and existence. The destruction of this layer has been linked to the now common health conditions such as cancers, skin conditions and cataracts among others. It is apparent that, without the ozone layer, all humanity would be lost to disease.

Aerosol particles originate from a wide variety of natural and anthropogenic sources. Aerosols can be grouped into primary and secondary particles. The primary particles are directly released from sources such as the incomplete combustion, volcanic eruption, human activities and wind-driven suspension of soil, dust, sea salt and biological material. While the secondary particles form within the atmosphere by interaction of the already existing particles. Depending on their density aerosols have a potential to reach as far as the stratosphere where majority of the ozone is found. Although majority of the ozone is found in the upper part of the atmosphere, it is still vital for human well-being. Ozone functions to protect

National Geographic wrote the article “Good Ozone, Bad Ozone”. The article is about how there are both good parts of the ozone layer and some bad parts of the ozone layer. The ozone layer is only good when the gas is high above the ground if it is not then it can be very harmful for us. The bad thing about the ozone layer is it is made up of poisonous gasses. Approximately 90 percent of the earth’s ozone is called the stratosphere. Many scientists believe that ozone layer is being destroyed due to chemicals we use. The National Geographic was motivated to write this article to educate us on how the ozone layer has a good and a bad layer. Even though, the ozone layer is helpful because it protects us from harmful ultraviolet rays. It can be bad when the layer is depleted and
