Ozone Depletion
The world's ozone is depleting on a daily base. Individuals and industries are to
blame. If we don't slow down what is being introduced to the atmosphere, the effects on
humans and the earth will be devastating. We must stop killing the earth's ozone by
watching what CFC's get released, car pooling to control automobile emissions, and stop
industries from polluting our atmosphere. The problems with a depleting ozone layer are
an increase in skin cancer, global warming of the earth, and a greenhouse effect on the
world. Stop and look at what we can do to resolve these problems.
Chorofluorocarbons (CFC's) are used today for coolants in refrigeration for air
conditioning, propellants in aerosol spray cans, and as solvents in the production of
electronic equipment ( CQ Researcher 303). When CFC's are released into the
atmosphere, they drift upwards until they reach the ozone layer. When CFC's remain in
their original molecule form they are harmless (CQ Researcher 303). When ultraviolet
rays come in contact with the CFC, it breaks down the molecule part. The CFC cell
attaches to the ozone layer and begins multiplying and braking down the ozone layer.
Ozone destroying chemicals are extremely stable, so they last in the atmosphere for many
decades. That means that if production of CFC's and halons stopped today, the chemicals
already released into the atmosphere would go on destroying ozone well into the 21st
century. There is an ozone hole over Antarctic, it was discovered in 1985. Since CFC's
are still in air conditioners and refrigerators, releases and malfunctions from these
existing units could ...

One of the greatest problems facing humanity is global climate change. Global climate change is the increase in average global temperature, caused by an increase in greenhouse gases. Greenhouse gases are the blanket of gases surrounding the earth that allows the world to be inhabitable. This layer of water vapor, carbon dioxide, methane, and other gases works. in the same way that a greenhouse does, by trapping heat energy inside the atmosphere.
When CFC molecules reach the stratosphere, the sun's radiation breaks it apart, freeing the chorine atom to destroy ozone molecules. The effect is a growing ozone hole which forms over Antarctica in October and usually lasts through mid November. During the annual ozone hole, the amount of UV radiation that reaches the Earth can double. Ozone depletion serves as a major health risk for human beings. The three primary health effects of ultraviolet radiation on human health are damage to the skin,eyes, and immune system.
What are the Causes of Global Warming?
Today, we take many of our natural resources for granted without think about the consequences. For example, cutting down trees, burning fossil fuel, and the consumption of meat. Our ozone layer is becoming weaker and weaker to due factories burning too much fossil fuel. This causes too much carbon dioxide, which affects our ozone layer. If we can limit the amount of natural resources we use on a daily basis, we will be able to see a big change in society.
Since the start of the Industrial Revolution, we have been using fossil fuels to power our lives, and factories. Little did we know that our miracle energy producer was destroying our planet. The burning of fossil fuels produces a byproduct called carbon dioxide. This natural occurring gas does not harm the planet in any way when released in small quantities, but at the rate we have released it, there is nowhere for it to go so it becomes trapped in the atmosphere. When the gas becomes trapped in the atmosphere, it creates a “Green House” effect. This effect causes the surface temperature to rise, which has adverse effects on the planet. A number of bills to regulate carbon dioxide released into the atmosphere have been proposed and even accepted,
Air pollution and greenhouse gases are the reason for the planet as it is today; the reason why we see campaigns flooding the media informing us to ‘switch off’, ‘save the planet’ and ‘turn down the heat’ and the reason why the government is trying to develop a successful scheme, such as the carbon tax scheme, to reduce air pollution caused by major industries. Air pollution and greenhouse gases are the two immediate causes of global warming and climate change. Air pollution occurs when chemicals or particulate matter enter the atmosphere. They can cause damage to living organisms on the planet, as well as destruction to the natural and synthetic environment (Energy Environment.net 2008). Greenhouse gases are gases in the atmosphere that absorb infrared radiation emitted from the earth. They trap infrared radiation in the form of heat, and hence contribute to global warming. Anthropogenic greenhouse gases are a direct result of air pollution. They are the physical gases emitted that cause air pollution. Naturally occurring greenhouse gases also have an influence on the earth’s atmosphere, though it is not as conspicuous as anthropogenic causes. Together, air pollution and greenhouse gases are intensifying climate change and global warming on a world-wide basis.

The ozone layer diminishes more each year. As the area of polar ozone depletion (commonly called the ozone hole) gets larger, additional ultraviolet rays are allowed to pass through. These rays cause cancer, cataracts, and lowered immunity to diseases.1 What causes the depletion of the ozone layer?
It is unfortunate that within the past 100 years our worlds' economy has driven itself into a deep hole with the reliance on a "black gold" called oil. Since its discovery, it has been purified to produce many different forms of energy such as light, gasoline and more. Since technology has enabled mankind to discover more capable methods of transportation, mankind has exploited its power over nature and produced machines such as the combustion engine. In combustion engine's, oil explodes to move machinery, and emits a very toxic byproduct called CO2. Carbon is incredibly dangerous to the earth's atmosphere, and erodes huge holes in the ozone layer of our earth. This erosion causes global warming and climate change that is permanent and irreversible. The impact of global warming will not only ...
The ozone layer must continue to be protected and we, as individuals, need to take the right steps into preserving our atmosphere and environment by finding new ways to prevent the ongoing destruction that has been done to it. If everyone does his or her part to help, no matter how big or small, we can ensure that this problem will be solved.
After nearly a century of use, CFC’s have finally been almost totally eliminated from production on the face of the planet. It seems as though we have finally taken a step in the right direction as far as preserving our ozone and our climate. Unfortunately, the repercussions of CFC’s will not go away anytime in the near future. Their effects will be felt well into the next century, as they continue to eat up what remains of our ozone and heat up our planet. Even after all of the CFC’s have decomposed, it will take generations before the ozone can begin to regenerate. That is one positive aspect of all this, and our future depends on it -- the damage done today is not irreversible -- but without immediate and drastic action, it will be.
As we approach the future we are faced with many global problems. Most of these problems arise because we have caused them ourselves. We need to face these problems and find a solution. Global warming, although most often overlooked in importance, is a crucial problem of the future directly related to human activities. Global warming is caused by gases humans release into the atmosphere called anthropogenic gases and by deforestation. Anthropogenic gases include carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofl...
In conclusion, without doubt we are destroying our planet Earth without noticing. The earth itself causes natural sources that lead to air pollution and the somehow are capable to recover from those sources; Nevertheless, as human continues with the use of fossil fuels as dependence of industrialization, then our planet will be getting worse. At cause of acid rain, carbon dioxide and sulfur dioxide, many people are suffering from cancer and other diseases due to the high level of contamination in the air and causing a high amount of death every year
which we call global warming, which in turn can have several effects on the planet.
