The water stored in the aquifers is being pumped out of the ground faster than it is replenished. According to USGS, “The volume of groundwater in storage is decreasing in many areas of the United States in response to pumping. Groundwater depletion is primarily caused by sustained groundwater pumping”. Some of the causes of groundwater depletion are the drying up of wells, drastic reduction of water in streams and lakes, and increased pumping costs. There is also the deterioration of our water quality due to illegal dumping of hazardous chemicals into lakes, rivers, and the ground near them which contaminates these areas. “Groundwater pumping can alter how water moves between an aquifer and a stream, lake, or wetland by either intercepting groundwater flow that discharges into the surface-water body under natural conditions, or by increasing the rate of water movement from the surface-water body into an aquifer” (USGS). An effect of groundwater pumping is the water levels below the surface decreases and the plants, vegetation, and some wildlife die because they need it survive. One of the locations on the Atlantic Coastal Plain that is experiencing the effects related to groundwater depletion is the Floridian Aquifer. The surface water flows have been reduced partly because of the saltwater intrusion that is occurring in the coastal areas of Brunswick and Savannah, Georgia, and Jacksonville and Miami, Florida. In central Florida the commercial and residential development has ultimately led to saltwater intrusion which has at times taken on in the form of sinkholes. There is also great concern about surface-water depletion from lakes in the area. This is also becoming a large problem in northern central part of Florida as well. The Floridian aquifer lies underneath the whole state of Florida, most of southern Georgia, and also in some parts of Alabama and…...

...Hollywood. One of the most popular is fiction. According to Wikipedia.org, “Fiction is a form of any narrative or informative work that deals, in part or in whole, with information or events that are not factual, but rather imaginary”.

It also features spacecrafts, space travels, robots, and other forms of technology with a more futuristic element. One purpose of Sci-Fi is exploring the consequences of scientific innovations (Maxiogee, 2007). Studying the influence of Science-Fiction films is important so that we can assess how the viewers act in response to what they watch on the big screen that focuses on stories and events that originated in someone else’s fantasy and imagination, and is never going to be true to life.

...Amazon rainforest As Brazil continues to grow, the demand for resources and land has increased along with the population. The population growth rate is estimated be 0.8 percent (2014 EST). Maintaining sustainable management of the Amazon rainforest can be a difficult, but important task that shouldn't be overlooked. Brazil needs to take advantage of the resources that the forest has to offer in order to develop, so not taking advantage of the rainforest is not an option. Exploiting the forest can have some irreversible damage such as climate change, soil erosion, and flooding can all be effects of unchecked exploitation ("Sustainable Management of The Forest", N.D). Sustainable management will allow for Brazil to develop without compromising the integrity of the rainforest. According to ("Sustainable Management of The Forest", N.D) Possible strategies that may help conserve, or at least minimize the human footprint. “Agro-forestry - growing trees and crops at the same time. This lets farmers take advantage of the shelter of the canopy of trees. It prevents soil erosion and the crops benefit from the nutrients from the dead organic matter.” Because of the nutrients left behind from dead matter, farms have natural fertilizer for the crops they may choose to grow.

...Oil Spills in Water SCI/256 Louise Morell Oil is one natural resource that has been maintained for the most part around the world. It has had its positive and negative effects on the human population as well as in agriculture. Several practices have been put into place in order to manage the sustainability of oil. Countries around the world cross-train and share ways on how to be more conservative with this energy resource. With all of these practices in place, there is irreparable damage in the freshwater aquatic and marine ecosystems when oil is deposited into the environment. Oil spills are something that can affect large bodies of water as well as small. It has been made known the affects it has had on oil drilling in our oceans but, oil spills can happen accidently or due to poor drilling practices in local areas as well. In the freshwater and aquatic arena, oil can be found. Rarely does it exist in its fundamental state as in most areas it must be processed. Although it is a natural resource, it is considered a localized resource due to it being found only in certain areas. It is also an exhaustible resource, which means that it is something that can run out, unlike air. When there is an oil spill in the freshwater or marine ecosystem, there is no mixture of these two liquids as the two are immiscible. Unfortunately the freshwater, which serves as a nesting ground and food source for many different species, it creates a threat to the inhabitants who......

...Final Examination Paper SCI/256 Timothy Woodland 22 November 2015 The climate of Georgia is typical of a humid subtropical climate with most of the state having mild winters and hot summers. The Atlantic Ocean on the east coast of Georgia and the hill country in the north impact the state's climate. Also, the Chattahoochee River divides Georgia into separate climatic regions with the mountain region to the northwest being colder than the rest of the state, the average temperatures for that region in January and July being 39 °F and 78 °F respectively. Winter in Georgia is characterized by mild temperatures and little snowfall around the state, with colder, snowier, and icier weather more likely across northern and central Georgia. Summer daytime temperatures in Georgia often exceed 90 °. The state experiences widespread precipitation. Tornadoes and tropical cyclones are common. Since moving to Georgia in 2007, there were a few issues that concerned me. The swamps that were in our training areas were full of life and yet we continued to build on them moving the wild life out. Then there was the issue that every year during Spring Break, thousands of college students would make their way to Tybee Island so that they may party for two weeks on the beach.

...Check Point Mitosis and Meiosis Joni Groves SCI/230 Yasmin Henry 08/10/2011 Check Point Mitosis and Meiosis The process of Mitosis and Meiosis are very important in their own individual ways. As stated in our reading material these are the differences between the two processes: Mitosis is a form of cellular reproduction in which the parent cell divides, giving rise to two daughter cells that are genetically identical to each other and to the parent cell. Mitosis does not involve combining genetic information from two different parents; hence, it is a form of asexual cellular reproduction. It occurs when an organism grows, or when damaged or worn cells are replaced. Many unicellular organisms reproduce asexually by mitosis, as well. Meiosis and mitosis have some similarities, but they differ in important ways that reflect the special role that gametes play in the life history of organisms. Whereas mitosis is asexual cellular reproduction, meiosis is a prelude to sexual reproduction. Meiosis results not only in multiplying the number of cells by cell division, but also in reducing the number of chromosomes in each daughter cell to exactly one-half of the number before meiosis. An organism would have to undergo Mitosis when the organism needs to repair itself, when the organism grows, or unicellular organisms reproduce asexually by mitosis, as well. Meiosis is what happens to cells when forming a person or animal. This cell division is in the bases of sexual......
