Hurricane Katrina was a category five hurricane of the 2005 Atlantic hurricane season [This sentence isn't technically incorrect, but it is a bit awkwardly worded.]. It hit the area of New Orleans, Louisiana with great force, causing much destruction. It became one of the worst natural disasters in the history of the United States. A Hurricane in general can be compared to a bulldozer. People know a bulldozer’s capabilities and people prepare for and know how much damage they are going to do. The comparison between Hurricane Katrina and a bulldozer is an example of an analogy. Analogies are, “Finding similarities in some respect between things that are otherwise dissimilar” (dictionary.com). Obviously a bulldozer is very different from Hurricane Katrina, it doesn't match the powerful destruction of such a natural disaster. Analogies require relevant similarities. The effect of a bulldozer to a small piece of land is equivalent to the effect of Hurricane Katrina on New Orleans, it is just a larger medium. Specifically[,] these two can be compared through the fact that both: perform earth moving jobs, have costly effects, and as time goes by their power of destruction increases. [You shouldn't need to be this explicit about the fact that you are making an argument by analogy.]
After Hurricane Katrina had come and gone, most of the city was destroyed. Schools, buildings, shopping malls,[:] everything lying in its path was affected. Great wind and rain caused the uplifting of structures and trees. This destruction can be compared to that of a bulldozer, although to a much smaller degree. In the late 1800’s, the term bulldozing, meant using a big force to push over or through any obstacle. In other words, they both perform earth-moving jobs. A bulldozer is equipped with a large, thick metal plate in front called a “blade” which peels layers of soil and pushes it forward as it advances. As the hurricane moved or advanced through New Orleans, it caused lakes to overflow and flood the area. The water pushed its way through and dragged all obstacles along that got in its way. Both a bulldozer and a Hurricane have the power to advance through a region and destroy everything in its path.
Hurricane Katrina was named the most destructive and costliest natural disaster in the history of the United States. It left damage costing millions of dollars to repair. Even in some areas that were affected, businesses and homes are too damaged to be fixed. Parts of New Orleans will never be the same. A bulldozer is used to tear through establishments, but the difference is that it is by ones request. This too is a very costly process. It is expensive to have something torn down which was once also very costly to build. Although the cost of repairing New Orleans after Hurricane Katrina greatly exceeds that of bulldozing, they are similar because they both involve the spending of money due to the destruction of something.
Hurricanes are getting more powerful and harder to predict [is this true?]. Katrina was one of many to hit the United States but had a much greater impact than the others before it. Like Hurricanes, bulldozers are getting bigger and more forceful throughout the years. People are coming up with new ways to improve this powerful machine to get the job done more efficiently. As an option, they can be equipped with rear ripper claw to loosen rocky soil or to break up pavement roads. Nevertheless, we do not “make” the hurricane stronger, but we should expect it and be more prepared and ready for the next time it hits. [don't you think the argument could be made that the hurricane swas so much more destructive because of the large increase in people living on the coast?]
It is hard to compare such a deadly natural disaster as Hurricane Katrina to a manpowered piece of machinery, but it [in] more ways than one, they are very similar. Comparing Hurricane Katrina to a bulldozer is an example of an analogy. Analogies are used to better explain something and in this case, the effect and power of Hurricane Katrina on New Orleans. For example, if a young child that did not quite comprehend a situation, an analogy to something that they are familiar with can be used. They may not fully understand Hurricane Katrina but when compared to a bulldozer, an object they are familiar with, they can picture the damage done by a bulldozer, enlarging the effects over an entire city. Both Hurricane Katrina and a bulldozer cause permanent, expensive damage to land and buildings, using their strength and force to destroy everything in their paths. [Okay, that was a good point. I see why you brought up the definition of "analogy" earlier on. Not a bad strategy, after all. Good conclusion.]
