is slowly disappearing.(“Virgin Islands”) "There are not as many reef fish as there used to be; there's more algae, more coral diseases, and more reefs that ... are now simply gone," says Ginger Garrison, a marine ecologist with the United States Geological Survey (USGS). Virgin Islands National Park is a protected area on St. John's island that is facing many problems beneath the waters. Beneath its facade, the reef is sick. Around the 1980's, it was suspected at least three diseases had swept

Abstract The human race has advanced a great deal over the course of recent history, particularly so since the 18th century. Countless of these developments in society can be attributed to the achievements of engineers - however, despite this, many do not realise their contribution and importance. One of the fundamental bases behind these engineering feats is the harnessing of energy sources, such as electrical and heat energy. This has allowed for many innovations, for example power stations, transportation

What is the role played by scarcity of resources in a given historical period? By the standards of the last decade of the 19th century, the question of scarcity of water whether purposed for agricultural irrigation, bourgeois refinements like bathtubs, social and religious obligations like Christian baptism or Mormon proxy-baptism of the dead, and indeed as a beverage that even Temperance crusaders like Mrs Rutherford B Hayes could approve seemed like a necessity for settling of arid regions, and

Earth’s Changing Climate: The Transformation of the Arctic Professor Pollack’s lecture on the transformation of the Arctic provided a good overview on the potential socio-economic and geopolitical impacts brought by climate change. The harsh conditions, severe storms, ice cover, and long periods of darkness in the Arctic have made human exploration and habitation difficult. Driven largely by interacting forces of climate change and increased human activities, the Arctic region is warming at twice

Two-thirds of those lakes are located within the four counties that surround Orlando. With so many lakes, whether man-made or natural, there are abundant species of wildlife that count on these lakes in and around Orlando. Writing in the United States Geological Survey publication, "Hydrology of Central Florida Lakes," Donna M. Schiffer

Fire! Most people are alarmed with that word. But fire is a major factor in allowing the grasslands to exist. Native Americans used to burn prairies to get rid of all of the dead grass and allow the new grass to grow for the bison to eat. Burning off grasslands in the spring permits the grass to grow without being restricted by the old, dead grass. Fire also kills the parasites and flies that bother the cattle in the summer. Invasive cedar trees overtake grasses and starve out good native grasses

In 1848, the treaty of Guadalupe Hidalgo made the Grand Canyon area part of the United States. The canyon attracted the attention of many. The Pacific Railroad Survey made the first official geological observations of the Grand Canyon area in 1856. A Mormon missionary named Jacob Hamblin was sent to the Grand Canyon in order to find good river crossing sites. Hamblin built good relationships

Harry Davis 9/2/15 APES Period 1 An Analysis of the Challenges Facing the Arctic Ocean The Arctic is a covers a vast expanse of the Earth. It is touched by 8 different countries, including Russia and the United States. It is an area of extreme economic and scientific interest, being one of the last frontiers not yet completely explored or conquered on planet Earth. Can the Arctic be both an economic powerhouse and an ecological preserve? The answer to this question is yes, it is possible, but

The United States Geological Survey (USGS) estimates that there are roughly 500,000 measureable earthquakes each year with 100 of the temblors causing damage (“Earthquake Facts,” n.d.). Much of the world’s population lives near the plate boundaries and faults where earthquakes are the most prevalent. Modern geologists and seismologists have developed techniques to help mitigate the geologic phenomenon’s catastrophic effects, but their ability to predict earthquakes is deeply mired in the nebulous
