Unit 5 Assignment - Global Warming This paper will define global warming and discuss how greenhouse gases affect the Earth. While greenhouse gases are necessary for life to exist on Earth, an overabundance or shortage of greenhouse gases can be detrimental. Human activities have caused an overabundance of these gases, and it is necessary for humans to become aware of how their activities affect the Earth. It is necessary for humans to begin modifying their behaviors that cause global warming and

Our Earth was formed 45 hundred million years ago as a mixture of rocks, and there was creatures under the sea starting to grow 2.5-6 hundred million years ago, since when there have been more and more species being found. Thanks to the plants and solar energy, human beings are able to live on this planet. Meanwhile, the weather on Earth changes all the time, and affects our lives. People rely on animals, plants and water, which are all affected by the climate. Besides, for more purposes, people

“Global warming is controversial, of course, but the controversy is mainly over whether human activity is driving it (Michio Kaku).” For years, the suspect or suspects that cause global warming have been unknown. Two of the well-assumed and controversial possible defendants are balancing on a slightly unbalanced seesaw with scientific evidence that back up or refute their degree of involvement in the crisis. There is evidence that global warming is taking a toll on the earth and will continue to

it damage the air, it is also a hazard to human and animal health. Particles from the pollution can easily lodge themselves into lungs, and cause many problems in the body. Another type of environmental degradation of air is the depletion of the ozone layer. If the ozone layer is damaged, lots of ultra-violet rays from the sun will be able to reach the Earth’s surface. Excessive amounts of ultra-violet radiation could cause numerous problems for human health including skin and eyesight

Negative Externality Pollution Negative Externality: Pollution Pollution has become a heated issue in recent years. The destruction of the environment along with serious health problems are the eventual effects. The extensive use and availability of automobiles, tremendous amounts of production in the booming economy and the constant increase in demand for energy, can be held responsible. Pollution and its effects can definitely be categorized as negative externalities. Although millions

2013. Web. 14 Apr. 2015). One of the most and perhaps the most controversial environmental degradation factor is the global warming. There are greenhouse gases that are naturally at the atmosphere. They include; carbon dioxide, water vapor, methane, ozone and the nitrous oxide. Therefore, global warming results from the process whereby the natural levels of these

precipitation, delay in the recovery of the Artic and Antarctic ozone and rapid warming in the case where use of sulfate aerosols are abruptly ceased (Goldstein 2010). The most concerning of these is depletion of the Arctic poles ozone. Tilmes (2008, p.1201) explains that “An injection of sulphur large enough to compensate for surface warming caused by the doubling of atmospheric CO2 would strongly increase the extent of Arctic ozone depletion during the present century for cold winters and would cause

employment areas away from the middlemen to the two working ends of the process, resulting in increased productivity and efficiency in many fields in society. Chemical Knowledge: Chlorofluorocarbons Growth of the hole in the Ozone Layer Growth of the hole in the Ozone Layer In the 1930s chlorofluorocarbons (CFCs) became an industrial staple due to their

be atmospheric gasses. Another vocabulary word to define which is also an effect from global warming is the ozone hole. This is defined as “An area of the ozone layer, such as the large area over Antarctica or the smaller area over the North Pole, that periodically becomes depleted of ozone.” (ProQuest Staff) The greenhouse effect is how our planet is continuously warming up and the ozone hole is one of many negative effects caused by the harmful emissions that mostly humans emit into our planet’s
