Environmental Effects Of Ozone Depletion

Enviropigs were produced to reduce the amount of pollutant waist, hog farms could raise significantly more hogs, and help meet environmental regulations. One of the reasons why the enviropig fail, was the lack of investment in continuing to study enviropigs and the company wanted to put more money towards other efficiencies in meat production. People were also very afraid to eat them, with fears the long term effects on their health. The enviropigs were also never tested for its effects on human allergies, since this type of food was never in there diets before. The best way to decrease environments impacts, is to decrease the amount of meat that is consumed.

However, the effect of this process was unknown. Within three months, the pair developed the CFC ozone depletion theory. They determined that as the CFCs are broken down by solar radiation, the chlorine atoms are released into the atmosphere. As the chlorine atoms encounter ozone molecules, the two react to form chlorine oxide and an oxygen molecule. When the chlorine oxide molecule encounters another ozone molecule, two oxygen molecules form, the chlorine molecule is released, and the process begins again. Molina determined that over 100,000 ozone molecules could be destroyed by a single chlorine atom. In addition, CFCs could contain up to four atoms of chlorine per molecule. Molina predicted that in 60 years, CFCs could destroy 7% of the ozone in the earth's

According to Allen, “The sun radiates energy in a wide range of wavelengths, most of which are invisible to human eyes. The shorter the wavelength, the more energetic the radiation, and the greater the potential for harm. Ultraviolet (UV) radiation that reaches the Earth’s surface is in wavelengths between 290 and 400 nm (nanometers, or billionths of a meter). This is shorter than wavelengths of visible light, which are 400 to 700 nm.” When these UV rays hit your skin, they can directly damage your DNA, cause a painful burn, and premature the aging of the skin, which are caused by UVA. The UV rays that we are exposed to are UVA and UVB rays. (Sottery) UVA is a long, flowy line and UVB is a tighter, patterned line. UVA rays contribute to melanoma, deeply passes through skin, affects skin at any time of day, passes through clouds and glass, and is responsible for about 95% of UV radiation that reaches earth. UVB can burn skin, passes the skin’s outer layer only, affects skin most intensely during summer, causes near-immediate effects, can partially penetrate clouds but not glass, can contribute to skin cancer, and accounts for about 5% of the sun’s energy that reaches earth.

How do CFCs or chlorofluorocarbons affect Canada’s Ozone layer. To answer this question we first have to understand chlorofluorocarbons and the earth's ozone layer. Chlorofluorocarbons are chemical compounds made up of three chlorine atoms. One fluorine atom and 1 carbon atom. There were many uses for CFCs ranging from, being used as coolants in refrigerants to propellants for aerosols to being used as solvents for dry cleaning. As CFCs are non- flammable and not very toxic we thought they were a revolutionary compound, but unfortunately CFCs were one of the leading causes for the depletion of our ozone layer. ozone is a type of oxygen, an ozone molecule consists of three oxygen atoms whereas a regular oxygen molecule only consists of two.

Ultraviolet (UV) radiation is present in normal sunlight and sunlamps. “The sun emits energy over a broad spectrum of wavelengths: visible light that [one] can see, infrared radiation that [one] feels as heat, and ultraviolet (UV) radiation that [one] cannot see or feel. UV radiation has a shorter wavelength and higher energy than visible light. It affects human health both positively and negatively” (U.S. EPA). There are multiple types of ultraviolet radiation known to scientists and each affects human in different ways. “The longer ultraviolet rays (UVA), which penetrate deep into the skin, are responsible for tanning. Shorter rays (UVB) damage superficial skin cell layers, causing sunburn” (Harvard). Medical researchers at the Skin Cancer Foundation found that “the cumulative damage caused by UV radiation can lead to premature skin aging (wrinkles, lax skin, brown spots, and more), as well as skin cancer” (Skin Cancer Foundation).

From the beginning of the spraying 51 years ago, and even today, millions of Vietnamese have died from, or been completely incapacitated by, diseases which the US government recognizes are related to Agent Orange, according to Truth-out.org. Many people refuse to believe that Agent Orange had any bad or harmful effect on the environment and on people. In my opinion, Agent Orange was a very deadly toxin, has had a very big and negative impact on both the environment in Vietnam and other countries around the world, and it has had a big and negative impact on people by causing diseases and disorders.

According to the United States Environmental Protection Agency (2010), ultraviolet (UV) rays are remarkably damaging to the skin without the proper protection. The National Weather Service and the EPA have developed the UV Index, a tool that predicts the level of UV radiation and indicates the risk, numerically. It is scale in which 0-2 indicates low risk of danger from sun rays, 3-5 indicates moderate risk, 6-7 indicates high risk, 8-10 indicates very high risk, and 11+ indicates extreme risk of harm. There are a considerable number of factors that influence an ultraviolet level, including stratospheric ozone layer, time of day, time of year, latitude, altitude, weather

Ozone also known as O3, is a colorless toxic gas formed by three oxygen atoms. The ozone occurs in the Earth’s upper atmosphere, the stratosphere and in the lower atmosphere, the troposphere. The ozone can affect life in a good or bad way. Good ozone is in the upper atmosphere and occurs naturally, it has a protective layer that helps block harmful ultraviolet rays (EPA.Gov). Stratospheric ozone is formed naturally and it is about 6 through 30 miles above the Earth’s surface and it also reduces the amount of harmful UV rays. Bad ozone is created by chemical reactions of oxides of nitrogen (NOx) and volatile organic compounds (VOCs) (EPA.Gov). Tropospheric or ground-level ozone is what we breathe and are formed by chemical reactions of NOx and VOCs, these reactions have been viewed by the presence of heat and sunlight, resulting in higher ozone levels in the summer. The purpose of this paper is to identify the difference ozone levels in San

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

Ultraviolet light (UV) Introduction The ultraviolet light is found around our lives, even if we do not concern about it too much. It is a kind of electromagnetic radiation that comes from the sun and people can not notice it with their eyes. The UV light only embodies 10% in the sun, and merely a little part reach on the ground. The UV light has the shorter wavelengths than the others. In addition, it also benefits our lives. We use the UV light on the periodontics, cleaning, the discovering of the real money, or dry out our nail. On the other hands, the UV light also has some negative impacts in our human bodies, the UV light mainly absorbed in the superficial, which means the dead layer of the epidermis.It can cause corneal burns, sunburn, seriously cause the skin cancer. Although it

We often hear, especially in the warmer months of the year, about how we ought to be protecting ourselves from UV exposure. We are told of the importance of sunscreen and keeping ourselves covered when in direct sunlight. But why is protecting ourselves from UV light so important? According to the website, Livescience.com, UV light, or ultraviolet light, is a type of electromagnetic radiation that comes from the sun. You cannot see UV rays, which may be one of the things that makes it so dangerous. UV light can be very harmful to our bodies if we are exposed to too much, in one way, specifically, by sunburning. Every day, we are partially protected from UV light by the ozone layer. Nationalgeographic.com defined the ozone layer to be “a naturally

UV radiation is a necessity for all life on Earth. The visible wavelength of photosynthetically active light ranges from 400 to 700 nm. This phenomenon provides the energy needed for photosynthesis, which supports the production of oxygen in the atmosphere at levels adequate enough for breathing and the carbon cycle in the biosphere. These wavelengths of solar radiation add heat to the atmosphere of Earth and maintains temperatures that allow life to thrive. Shorter UV wavelengths interact with molecular oxygen mainly in the stratosphere. This interaction leads to the production of ozone, which protects biological systems in the troposphere from the extremely toxic UV-B wavelengths. Excess exposure to UV radiation can also disrupt biological

An ultraviolet wave is an electromagnetic radiation with a wavelength of 10^-8 meters and a frequency of 10^15 nm. Hospitals use UV lamps to sterilize surgical equipment and the air in operating theaters. Food and drug companies also use UV lamps to sterilize their products.UV rays can also damage the eyes and can ultimately lead to blindness. Melanoma, a type of skin cancer, can also develop within the eye. Ultraviolet (UV) radiation is a form of electromagnetic radiation that lies between visible light and x rays in its energy and wavelength. It is a component of the radiation that reaches the Earth from the

These chemicals, once released, take quite a long time to degrade. It takes them years to move through the atmosphere to the location of the ozone layer. These chemicals are broken down by the ultra violet rays from the sun ultimately breaking down into chlorine and bromide molecules which are responsible for the destruction of the ozone layer. Ozone layer is found in two layers i.e. the “good” and “bad” ozone layer (Filder 131). The bromide and chloride atoms destroy the “good” ozone. One molecule of chlorine is estimated to be capable of
