Task:

A. Create a multimedia presentation (e.g. PowerPoint, Keynote) (suggested length of 6–8 slides) that introduces and describes your chosen ecosystem, analyzes the impact of human activity on the ecosystem, and provides guidelines to help preserve your chosen ecosystem. Do the following in your presentation:
1. Describe the specific ecosystem that you have selected by doing the following:
a. Identify the specific geographic location of the ecosystem.

Note: You can use maps, written description of location, and latitude/longitude to provide the location of the ecosystem.

b. Explain the major biotic and abiotic components of the ecosystem.
2. Discuss the impact that humans currently have on the specified ecosystem.
3. Predict the effect of future human impact on the specified ecosystem.
4. Provide guidelines regarding human activities that will aid in preserving the specified ecosystem.

B. If you choose to use outside sources, include all in-text citations and references in APA format.

for Reference:
Map of Chernobyl retrived from http://www.greenfacts.org/en/chernobyl/figtableboxes/map-chernobyl.htm The novel emphasizes that the "dead zone" around Chernobyl is actually rich in plant- and wildlife (which have tolerance levels for radiation different than humans).
In this area, wild animals such as wolves have not only flourished in the absence of human activity, but have no fear of the humans they do encounter.

Flora and fauna
There has been an ongoing scientific debate about the extent to which flora and fauna of the zone were affected by the radioactive contamination that followed the accident. Cases of mutant deformity in animals of the zone include partial albinism and other external malformations in swallows[2][3][4] and insect mutations.[5] A study of several hundred birds belonging to 48 different species also demonstrated that birds inhabiting highly radioactively contaminated areas had smaller brains compared to birds from clean areas.[6]
There have been individual eyewitness reports of other animal mutations. The cloud of heavily polluted dust left the Red Forest (Рудий ліс)—a stand of highly-irradiated pine wood near the plant which was subsequently bulldozed. A reduction in the density and the abundance of animals in highly radioactively contaminated areas has been demonstrated for several taxa, including birds,[7][8] insects and spiders, [9] and mammals. [10] In birds, which are an efficient bioindicator, species diversity decreases 50 percent in radioactively contaminated areas compared to clean areas, while abundance decreases by two thirds. There have been reports that wildlife has flourished due to significant reduction of human impact.[11] For this reason, the zone is considered by some as a classic example of an involuntary park. Some claim that the populations of traditional Polesian animals (like wolves, Badger, wild boar, Roe Deer, White-tailed Eagle, Black Stork), Western Marsh-harrier, Short-eared Owl, red deer, moose, Great Egret, Whooper Swan, least weasel, Common Kestrel and beaver) have multiplied enormously and begun expanding outside the zone. These claims, however, are not substantiated by any systematic census of any animal taxon. [12] The area also houses herds of European wisent (native to the area) and Przewalski's Horses (foreign to the area, as tarpan was the native wild horse) released there after the accident. Some accounts refer to the reappearance of extremely rare native lynx, and there are videos of brown bears and their cubs, an animal not seen in the area for more than a century. Special game warden units are organized to protect and control them. No scientific study has been conducted on the population dynamics of these species.
The rivers and lakes of the zone pose a significant threat of spreading polluted silt during spring floods. They are systematically secured by dykes.

Project Design Plan Int1 Task 3

...INT1 Task 3 Page 2 Project Design Plan This experiment asks the question, “What paper towel is more absorbent for the price per sheet?” Will the more costly paper towels absorb a bigger spill therefore giving the consumer reasoning on buying the higher priced paper towel? This experiment will examine the absorbency of three different brands of paper towels and then compare the results to the price of the product to find the absorbency value. First, we will purchase one roll from three different brands of paper towels from the same store at retail price. It’s important to purchase the products at full cost or note what the normal price is from the same store since different stores may have different prices. Different brands of paper towel rolls come with different amounts of sheets as well as sizes, so it will be important to have all the sample sizes the same for accurate results. The results will be drawn up after the controlled experiment is finished. The experiment will consist of taking an individual sheet from each brand of paper towel and spread it over a container and using a medicine dropper or eye dropper filled with water, squeeze drops onto the paper towel one at a time until the water starts to leak into the container below. Each drop will be counted up to the point where the water leaks into the container. This will be done three times with each......

There are torrential rains, cool nights and dry days. Rainfall is seldom and unpredictable. Streambeds are usually dry and there are only a few waterholes. The area has two distinct seasons, summer and winter. Temperatures can get as high as 130 degrees fahrenheit in the summer, and below 0 degrees fahrenheit in the winter time. The low desert called the Colorado goes up to 3,000 feet. The higher desert called the Mojave goes up to nearly 6,000 feet.

The Great Salt Lake

...The Great Salt Lake INT1 Task 2 (Ha’Eri, 2004) Location ● The Great Salt Lake is located in northern Utah. (USGS, n.d., b) Biotic Components ● ● ● ● ● ● ● Brine Shrimp Brine Flies Algae Ducks Geese Gulls Pelicans (Wikipedia, n.d.) (Wurstsbaugh, 2014, d) Abiotic Components -Surface elevation 4200 feet above sea level -Depth averages 14 feet -Railroad crosses through the lake -Averages 15.7 inches of precipitation per year -Water temperature varies from below freezing to 80 degrees Fahrenheit. (Gwynn, 2002) Current Human Impact -Humans building a railway through The Great Salt Lake has divided the lake and caused that half of the lake has a higher salinity percentage than the other half. This is caused by the South end has more fresh water flowing into it and the North end has more salt water flowing through it. Because of the railway, it doesn’t pass through to the other side. The percentage of salinity is affecting the brine shrimp eggs harvest. It has decreased. The residents in the Salt Lake area use more water than the average people in the country. Not conserving and using so much water is affecting the water levels of the Great Salt Lake. The lake is getting smaller each year. (USGS, 1999) Future Human Impacts -If current water usage trends continue, the lake will continue to get smaller and smaller. With future growth of the area expected to triple in the next 50 years, Utahns......
