...ECOSYSTEMS PAPER (LAKE TAHOE) SCI/256 Lake Tahoe is a large and a very beautiful lake in Nevada region of the United States. The surface are of the lake is about 191, 500 square miles. The average depth of the lake is about 300 meters. The lake is surrounded vegetation which supports a variety of plant life and animal life. The diversity of the organisms living around the lake is great. The vegetation around the lake consists of rain forests including species of Jeffry Pine, lodgepole Pine, white and red first. Vegetation also includes dry meadows and brush fields. The brush field Ceanothus has the capability of fixing nitrogen that makes the soil of the surrounding lake more fertile. There are several processes that prevail inside and outside the lake. The lake is under threat from eutrophication that can severely affect the aquatic life living in it and the surrounding vegetation. It has been estimated that there has been changes in the populations of the various aquatic animals living in the lake’s waters. Zooplankton population has faced the greatest changes. The lake experiences winter and summer seasons with full might. Temperatures can go as high as 25.9 degrees Celsius in the summer and as low as sub-zero in the winter. The vegetation surrounding the lake experiences these temperature changes and responds to this stimulus by the change in leaf colors and leaf numbers. The seasonal changes...

...When you’re considering North Carolina, The Appalachian Mountains are very bio-diverse regions in the world that would include latitude, altitude, topsoil types, immediacy seaside, and geologic time have gather for the advancement of numerous types of vegetation and animals. Many of the types are mutual across the globe yet some are prevalent to a handful of remote mountains in the vicinity. The most feasible way gain knowledge of this way of living is by alpinism. The setting around these mountains is immensely different, and includes various trees, bushes, and other foliage. Heavy rains spread evenly during the year and allow vegetation to survive. The budding starts in March for particular plants but carry on well up until November. Nevertheless, when you increase in altitude, seasons reduce significantly. Subsequently, forest communities travel up mountain sides and look like those that you’d encounter while traveling up to the northern areas. It's not exceptional to come across a multitude of different wildlife while in NC. In the Great Smoky Mountains, there are over 60 species not to forget bears, deer, and elk. You could quite possibly catch an opossum traveling across the road or highway and perchance a red squirrel will watch you from high up in a tree. If you're fortunate, or maybe even unfortunate, you may perhaps catch view of a bear. Mention of bears always raises a safety concern and although most animals in the wild are afraid of humans, it is imperative...

...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...

...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. Each year for those two weeks, the beaches were littered with trash and crews would have to clean up after them. Trash would be taken out into the ocean by the...

...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 rely...

...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. Selective logging trees that are a pre-determined height, in order to avoid cutting down younger trees ("Sustainable Management of The Forest", N.D).

...Discussion Questio SCI/256 November4,2013 Dr. Moseley Discussion Question3 With health care improvement, the age structure of the human population, mostly in developed countries, skewed toward the older population. Meaning the increasing percentage of the population is nearly consist of people near retirement. Especially, if the country is supporting social services, this means an increasing load on health care, pension, and all other services for senior citizens that must be with the tax increase as well as consumer goods and services costs for qualified people of age. Age composition of a population gives us important facts that one can use. For example; if there are older people and few you fewer young people, then we need to consider the birth control policies. If there is more young people than older people, medical implicates, that the health of the elderly are not being properly address. There is a social, economic as well as a political implications, too, since there is a population of majority of young people means there is little social guidance, and less of an older generation to teach the younger generation what one really need to know and knowledge availability to run a government or a business. Also, resources like food supplies and raw materials is affected by makeup age of a population, with different group age tending to consume resources in many ways , as if the bulge of young people, that is, going to reproduce, this one main concern...

What would you include in a brief summary on the history of the modern environmental movement, from the 1960s to the present? Back in the years of 1960 and 1962 there were many major environmental events that had occurred and changed the minds of society. Some of those major events were based on publicized threats, and oil spills of extinction of several species, causing the environment to become very popular. Society begins to gain the knowledge of understanding the importance as to what the environment meant and was able to do for them (The People) to survive. Today there are many organizations to help take care of the environment such as recycling, the use of gas and electricity, and also the use of plastic instead of paper to also help save many trees from being chopped down, which are needed for oxygen. 2.

I learn that pollution is wearing down our ecosystem and it is becoming less and less productive which is a problem for us in the future we need our ecosystem to help humans, earth, plants, water and our animals to produce healthy goods something I did not know too much about. Scientist has predict that humans will be the cause our ecosystem to perform less effective; what we do effects everything on earth living or dead. Humans play a major on earth and our ecosystem. We as humans need to pay more attention to the things we do on earth it is causing our system to perform less and less. I have learn everyone around the world is suffering from the same issues pollution, waterways and sewage. Also pollution is causing all kinds of health issues such lung cancer, asthma, heart problems, things of that nature. Like Anacostia River; our once clean fresh air and water, were at once upon a time we used pulled up the windows to let some fresh air come into house, is now polluted and you have be careful because the air we breathe now is full toxic chemicals that causes serious...

...Alternative Energy and the Environment Team C Tamara S, Kathy L, Lee B, Lacreasha D, Jon L SCI/256 12/21/2012 Costa Mazidji Alternative Energy and the Environment Solar energy is energy from the sun and without its presence all life on earth would end. It is now being looked upon as a serious source of energy for many years because of the vast amounts of energy that are made freely available, if harnessed by modern technology. The strength of solar energy is that solar energy uses solar emission by the sun. It does not cost and helps to eliminate or lower electricity bills. It does not need fuel nor have the possibility of polluting the environment. Solar energy is clean and does not let out carbon dioxide and other harmful gases. It is eco-friendly and helps decrease harmful emission of the Green House gases. Without its presence, Life on earth would end. Weakness of solar is energy is that solar energy is very costly. A considerable amount of energy is lost when DC (Direct Current) has to be converted to AC Alternating Current). Solar cells can only produce DC. Solar electricity and heat is not available at night and it’s not accessible in bad weather conditions. A solar or complementary power station is required which can be a problem for many locations. Solar Panels require a large area for installation in order to achieve a good level of efficiency. Solar energy can also be influenced by the...

...Vanessa Montes February 1st 2016 Sci/256 Professor John Jacobs Approximately 4.5 billion years before the Earth has been formed. It is very difficult to describe or flashback the millions years before what was the climate in the Earth in a particular place on particular day. However, unfortunately based on the some clues still remain in the rock, ice, trees, corals, and definitely on the fossils. Based on these clues it is clearly indicated that the Earth climate has changed many time before. There was a time period when the whole planet was covered with ice. Now the scenario has been totally changed. If we flashback just last 650,000 years back, there was an increased level of environmental carbon-di-oxide (CO2) and temperature and simultaneously decreased the cyclical pattern. Scientists have been studies and analyze enormous experimental trials to find out the better way and to understand the climate change in this planet. Some of the selective ways are following various weather forecast departments’ for the purpose of receiving the weather information send back to the earth viz. weather stations (for the measurement of temperature, rainfall, wind speed, and humidity; weather balloons (just float in a very high altitude in the atmosphere with a transmitter); weather satellites (sent a satellite to the space for getting the information regarding rainfall, temperature, cloud cover, etc.; ice cores (if...
