The Silence of the Limpkins by Susan Cerulean is about the overall degradation of Wakulla Springs. This story begins with the narrator describing how his colleagues and he have to put herbicide in Wakulla Springs every so often. As to clear the hydrilla, a plant imported from India because of a trade that overall massively impacted the Wakulla Springs ecosystem. “Hydrilla was imported to the United States from India for the indoor aquarium trade in the 1950’s. No one knew it would become a major invader of Florida’s lakes and rivers” (Susan Cerulean).
What would you include in a brief summary on the history of the environmental movement? Environmentalist can trace the history of environmental issue back to ancient times where air and water pollution as well as soil conservation were concerns for the ancestors of modern civilization. Places like ancient Rome was infamous for streets filled with sewage. During the Middle Ages, a plague in Europe as well as the use of coal for heating in England warranted concern with public health. As centuries came and went health problems increased.
Dear Board of Directors, The citizens of the city of Riverside are concerned with the pollution of Cherokee River and encourage the Kardell Paper Co. to switch to operational systems which are more environmentally friendly to reduce the health risks that are affecting our community. Our community is very concerned about the water quality of the Cherokee River. According to research, the river is currently contaminated with high traces of Sonox. The contaminants have been traced back to the industrial waste from the Kardell plant. The high readings of the contaminants shown were a result of tests conducted near the industrial pipes of the plant.
The El Niño Factor by Carl Zimmer in an article that describes El Niño and La Niña and their effects and causes. The article tells how El Niño and La Niña affect Water Temperature. Scientists have been studying El Niño because it has been causing disasters all over the world for many, many years. Scientists hope to be able to predict when El Niño will occur. The article talks about how El Niño affects people, it can cause diseases and food shortages as just two examples.
Running head: BORN TO THE LAND 1 Born to the Land BORN TO THE LAND 2 "Environmental history unites the oldest themes with the newest in contemporary historiography: the evolution of epidemics and climate, those two factors being integral parts of the human ecosystem; the series of natural calamities aggravated by a lack of foresight . . . ; the destruction of Nature, caused by soaring population and/or by the predators of industrial overconsumption; nuisances of urban and manufacturing origin, which lead to air or water pollution; human congestion or noise levels in urban areas, in a period of galloping urbanization,” stated Emmanuel Le Roy Ladurie. Environmental history is an all-encompassing
The release of a liquid petroleum hydrocarbon also known as an oil spill has a large negative effect on the ocean. Oil is commonly used by individuals however often oil can be a problem to organisms and their inhabitants. Oils spills are a form of pollution and there are various sources of oil in bodies of water. There are several scientific solutions for oil spills, as well as possible ways to prevent this harmful pollution. In 2010 ,172 million gallons of oil spilled from a whole on the ocean bed in the Gulf of Mexico.
The high content of carbon causes global warming and global warming causes climate change. These changes are destroying our blue planet and making the ecosystem become sicker. Unfortunately, all the high content of carbon was released by human activities. We must reduce Carbon Dioxide emissions in the next two to three years, or we will lose our natural environment that we depend upon for survival. The 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment.
Phytoplankton populations have also been affected by the warming temperatures in the ocean. Phytoplankton play a role in the conversion of carbon dioxide into organic carbon, and since the rising temperature of the ocean has caused a decrease in the phytoplankton population, higher carbon dioxide levels endanger other marine life, like the coral reefs mentioned earlier. Callum Roberts, a professor at the University of York, explains the importance of marine life by stating that, “They are essential to the health of the oceans and the well-being of
October 9, 2012 “Great Pacific Garbage Patch” Today’s society is facing a big problem with pollution, probably when we talk about pollution you just think about air pollution. But Captain. Charles Moore of the Algalita Marine Research Foundation discovered the Great Pacific Garbage Patch. The Pacific Garbage is an endless floating waste of plastic trash, that is killing many sea animals and underwater vegetation, but Captain Moore mission is to draw attention to the growing, and choking problem of plastic debris in our seas. The Great Pacific Patch stretch for hundreds of miles across the Pacific Ocean, basically the North part is forming a floating junkyard.
Since fish is the main target of mercury contamination, humans are at a lifethreatening risk by toxic effects mercury. Thus, production of toxic methyl-mercury in the upper ocean due to bio-accumulation and build-up of this poisonous compound in marine food web due to bio-magnification is of a vital concern for the humans. Study of marine biochemical cycle of mercury with its potential sources and sinks is really necessary to find effective remedies to diminish the dangerous effects of this shiny-white metal. This review presents biological and physical processes that drive biochemical cycle of mercury in the global oceans with the potential sources (such as river, atmosphere, sediments, and hydrothermal vents) and sinks (such as bioaccumulation in marine fish, and scavenging due to sinking particles). Spatial, vertical and temporal variations of elemental mercury and human exposure to deadly effects of methyl-mercury are also presented in this study.
