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.
Besides global warming there is another problem with this beautiful structure and that is the result of several local natural and human factors such as over fishing. Silt from deforested lands and pollution from crowded coastlines choke them, and overuse and destroy coral reefs. There are many other factors which if they are not stopped it will destroy all coral reefs. Corals are animals, not plants; sunlight is the key to their survival. They need it to power the millions of microscopic algae, called zooxanthellae, that live in their tissues.
First, the melting of ice caps and glaciers is releasing water into the oceans. Second, human activities, such as the burning of fossil fuels, combined with natural activities, it causes the rise of the earth's surface temperature.3 Second, climate change is already having a serious effect on every continent and throughout the world’s ocean. The consequences of sea level rise mainly reflected in three aspects: cultural heritages, indigenous communities and coastal lands. 4 First, sea level rise threats cultural world heritage. Data shows that 136 out of 700 listed cultural heritages throughout the world will be affected in the long term.
The Vanishing Islands and Atolls The Link to Climate Change and Global Warming Ricardo Pail Sarcar University of Saint Joseph Abstract In this study, I have investigated the climatological effects of global warming and climate change in relation to the vanishing islands and atolls of the Pacific, Atlantic and Indian Oceans to determine the adverse effects of climate change to these islands. Secondary data was reviewed my personal computer using Internet search engines. To aid the search, a table of key terms was constructed and the sources located will be correlated with this. The information I have extracted from my research shows that the rising temperatures have been causing a very unstable climate globally which in turn causes severe weather conditions such as floods and tsunamis which have been wiping atolls off the oceans. The rising temperatures have caused ice to melt in the Arctic and the North Pole which have been increasing the volume of water in the sea, gradually rising up to the shores of the islands and atolls.
Critical Analysis of a Claim: Shrimp Farming In An Appetite for Destruction, Dr. Mike Shanahan takes a look at the new found demand for shrimp throughout the world and the effect that this demand is having on global communities. Shanahan is arguing that shrimp farming, while it may conjure idyllic images to many, is actually a very devastating practice that has led to many deaths, violent protests and the destruction of communities economically and ecologically. The short article by Shanahan flows logically, providing readers with solid evidence to back claims with little wiggle room to claim bias. Shanahan’s bias as an environmental activist. It is often said that you find what you are looking for and facts can be presented to support almost any conclusion.
The Consequences of Overfishing Overfishing has been identified across the world as a prominent environmental issue. Fish and other marine animals, such as sharks, sea turtles and dolphin, are retrieved from the oceans through indiscriminate fishing practices at a rate that cannot be sustained by natural reproduction (Jackson, 2001). Systematic overfishing with bottom trawling, dredges, and drift nets depletes the ocean of innumerable species at an alarming rate and alters the ecological balance in marine environments. The actions of shortsighted commercial fishermen have brought tremendous adverse environmental and economic consequences upon the entire world. The continuation of unrestricted fishing will worsen world hunger among impoverished coastal communities, many of whom depend on the abundance of fish to feed themselves and their families, and result in ultimate environmental chaos and the extinction of thousands of In recent years, the demand for fish, a healthy food rich in omega-3 fatty acids and lean protein, has sky-rocketed.
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 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment. The film cites many recent climate change and natural disasters. Throughout the facts, we see that human life must depend on the natural environment. According to Thom Hartmann, “We are a part of nature. We can’t separate from nature.” As DiCaprio tells us we cannot survive without nature.
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.
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.
