Author: Jake Date: 12/09/2010 Introduction This essay includes my findings from research on the disease, and explains the signs, symptoms, causes, cures and prevention of the pathogen Cholera. The Bacterium Cholera is a severe bacterial infection caused by the bacterium “Vibrio cholerae”, the most common symptoms of the infection are diarrhoea ,vomiting and muscle cramps, this can lead to rapid dehydration and sometimes death. You can transmit Cholera by water that is contaminated with infected faeces; and also transmit it due to poor food hygiene1. Cholera kills an estimated 120,000 people a year2. If the bacteria enter the small intestine, they use their flagella to propel themselves through the lining of the intestinal wall, they produce a toxic protein.
Most of the impact of this was experienced by the marine species. Eight U.S. national parks were threatened and more than 400 species that live in the Gulf islands were at risk, including the endangered Kemp's Ridley turtle. The clean up of this travesty cost the government and companies billions to clear. As a result of the spill deep sea drilling in the Gulf was suspended until new safety measures had been put in place, costing governments and companies further millions, whilst the price of oil continued to rise. A spill in other deep sea areas such as the Arctic could accelerate damage in a very sensitive environment, which is already dangerously close to its
“Spooked” explored the history and hauntings of Waverly Hills. Waverly Hills has had a very historical past that many people will never know. Unless something is done, the history of Waverly Hills will be gone forever. It is estimated that the building will be completely destroyed within ten years if nothing is done to repair the damage that has occurred. Today, tuberculosis is nearly nonexistent thanks to the research that occurred at Waverly Hills and other TB sanatoriums around the world.
Environment is the surroundings and influences on living things including humans. Unfortunately, our actions impose severe and often irreversible damage on it and it will take a combination of lifestyle and industrial changes to address these issues successfully.

Oil had a slight peak of 12 tonnes in 1973, falling to a steady level of 10 [million] tonnes in the same year till 1979 before Deeping [dipping] to its lowest of 8 tonnes within the same year and maintaining the same
The collection mainly comprises ceramics and carved stone sculptures, especially the ceramic cups known as keros; these were ritually smashed and buried after ceremonial use. After our stop at the museum we'll begin our tour of the Ruins of Tiwanaku. Although it may have been inhabited as early as 1500BC as a farming village, Tiwanaku became an urban center starting aorund 300AD and grew in power over the next centuries, becoming a city-state, prestigious pilgrimage site, and the administrative center of the Kingdom of Tiwanaku, whose dominion expanded throughout Bolivia and into Chile and Peru. Around 1000AD the city fell due to drought, and any remaining scattered populations were conquered and assimilated for a brief period into the Inca Empire somewhere in the late 15th century or early 16th century. Despite years of abuse at the hands of tomb raiders and misguided excavations, the site still stuns with its giant stone monoliths (the largest block in the site weighs approximately 131 tons!)
Mystery of Mayan Civilization Fawn Barrette Professor Ewing Humanities 111 25 April 2012 Abstract What happened to the Maya civilization? It seems that around 800AD the Maya population had reached an all time high, but in 900AD the population crashed. (Scott, 2004) The people seemed to have simply disappeared and many theories evolved to try to explain this. Some of the theories are: earthquakes, climatic changes, epidemic diseases, social decay and deforestation and drought, but of course the Mayan people did not totally disappear and there are some Mayan descendants still living around the area and most of these theories have been disputed. The first theory is that widespread disease could have caused some rapid depopulation through the spread of infection itself and indirectly as an inhibition to recover over the long run.
Hilda Vidal, who is an Anthropologist (Study of humanity), discovered that Juanita’s skin began to unveil a different colour, from her normal dark brown colour, which was showed a sign of anxiety. No other reports of damage have been documented since.  Indeed, science played a massive role towards Juanita, and how she were to die. This may not only solve cases for ‘Juanita, the ice maiden’, but science may solve cases for over 10,000 peruvian mummies that were to die approximately 500 years
Scientific Whaling in the Southern Pacific Ocean, Effects on the Environment and Legislation. Introduction Whales have inhabited the earth’s oceans for millions of years and are a vital part of the ocean’s ecosystem. Since the 1600s, whales have been hunted out of the seas and no species has fully recovered. They also contend with pollution, climate change, ozone layer loss, overfishing, vessel traffic, noise and entanglement in fishing gear. Whales are mammals that live for a long time and breed slowly.
SOC, Wk 2 Activity-Assignment March, 14, 2013 Pollution in Richmond, California When chemical substances or energy to a natural environment surpasses, pollution is created. When these standard levels regulated by countries are exceeded, it can damage the ecosystem and living organisms. Various effects caused by pollution can be respiratory disease, cardiovascular disease, throat inflammation, chest pain, congestion and sometimes death. This Chevron refinery of 2,900 acres in Richmond, California, was completed 1902. The plant contained 19 stills that could process 10,000 barrels of crude a day and had a tankage capability of 185,000 barrels in its first year of setup and it has over 1,300 employees.
There are more than 10,000 different species of animals living in the Great Barrier Reef and some even never named by scientists. The formation of the Reef The sea floor on which the Great Barrier Reef now sits was formed about 500,000 years ago, however the Great Barrier Reef today is very different in size and shape as coral has continued to live on top of many layers of dead coral from centuries ago. The existing structure of the reef is about 6,000 to 8,000 years old. The current Great Barrier Reef began to form during the last Ice Age which occurred about 26,500 to 20,000 years ago according to scientific research, caused significant environmental changes in the area, including drastic drops in sea levels. Life in the Great Barrier Reef Some of the most unique and beautiful creatures in the world can be found in the Great Barrier Reef.
