Intro:
There are many environmental issues currently flowing through the media into society and raising some strong opinions and arguments. South Africa, being one of the world’s most diverse natural ecosystems, has come under the spotlight with regards to many issues such as the Karoo Fracking debacle and the Rhino Horn Poaching crisis. Unfortunately these issues are not represented only by the parties directly involved but rather by ‘gate keepers’, as we shall call them, who determine how the issue is framed and represented to the masses. The media has the ability to warp perspective and portray our role in the issue as they see fit. The debate about human’s place in nature is still one that creates many waves, and the media has a ‘knack’ for choosing sides. Should humans be allowed to control their environment in such a way that they exploit it purely for their own benefit rather than nurturing and caring for it as if it were a gift? This links to the theory of supremacy over animals which has been very controversial.
The issue that will be discussed hereafter is the debate about baiting for sharks using a method called chumming for a variety of purposes. “[It] is the practice of luring animals, usually fish such as sharks, by throwing ‘chum’ into the water. Chum often consists of fish parts and blood, which attract fish, particularly sharks owing to their keen sense of smell. Chumming is illegal in some parts of the world, such as Alabama, because of the danger it can pose by conditioning sharks to associating feeding with the presence of humans.” (Wikipedia, 2014).
Chumming is primarily used to attract sharks for the recreational purpose of shark cage diving but has been masked by the fact that it is also being used to lure ...

Shark nets have been implemented in locations across the world in response to shark sightings and attacks. Nets are submerged beneath the surface of the water, roughly 200 metres from the shoreline. The meshing is designed to be large to capture sharks, leaving them to struggle before eventually drowning under the weight of their own body. The meshing allows small fish to pass through, however captures larger fish and marine species. Shark nets provide no discrimination between common, vulnerable and endangered species, resulting in a high mortality rate for a variety of marine wildlife.
Nurse sharks were caught in the Florida Keys and transported to a facility in Sarasota, FL to carry out the experiment. The sharks were not given food 72 hours prior to the experiment and they were acclimated to the experimental temperatures (21-24C and 28-31C) for two weeks before. Individual sharks were moved to a closed respirometer 12 hours before the experiment so that they could recover from any handling stress before the trials. The trials were conducted in day and night conditions to account for the difference in behavior (more active at night). Throughout the trial, at regular intervals, dissolved oxygen and swimming speed were recorded.
Throughout the film there are many experts about the ocean and the animals that live in it. Researcher Ritter the misconception of the shark’s species is blown out of proportion by the media, which is why sharks have such an awful reputation. Experts touch up on this subject adding how even one of the biggest movies Jaws is a very large portion from where people get their fears from or it could be from all of the “shark attacks” on the news. Rob discusses how at the rate we are going we can destroy all of the food chains in the marine ecosystem, and this is where most of our oxygen comes from. Throughout the film experts Rob Stewart and Paul Watson are trying to get long lining banned in Costa Rica. Paul makes a really interesting point saying how the biggest problem is that we do not understand what we are and we are just a bunch of “conceited naked apes” that are out of
All the ways,that they came up with don’t only trap sharks they trap other sea life. Furthermore, you are trapping other animals that don’t even hurt humans and may be causing a Species to come Extinct by the sharks net. Nevertheless,
Fishery Scientist are constantly working on ways to protect shark species and reduce shark bite incidences. Others have proposed that sonar waves are placed on nets to try and keep sharks away. Researchers are also collecting data from the sharks that are caught by the fishermen to be in a position to better understand sharks, and how we can live in unity with them. A shark tagging programme to try to better understand shark movements and patterns could also assist instead of culling. Statistics show us that there have been drastic reductions in fatal shark bites since nets have been installed in NSW and Qld.
I think this wholesale framing of environmental justice issues solely or primarily in terms of distribution is seriously problematic. Drawing on both ecofeminist insights concerning the inextricable interconnections between institutions of human oppression and the domination of the natural ...
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
Thesis: Sharks should be conserved because they are an important part of the ocean, attacks are often incidental, and human behavior influences the behavior of sharks.
In Chinese tradition, Shark fin soup is called as “a celebration soup”, which people eat it to celebrate in various occasions. Moreover, people also believed that shark fin consisted of diverse nutrition values which provide them virility, wealth, and power(Wolchover, 2011). These beliefs lead to the beginning of poaching for sharks, the top of food chain in the sea world. Surprisingly, although people are aware of the decreasing number of sharks since the old days, around hundred million of sharks are still hunted each year(Heltus, 2013), to be served on luxury tables surrounded by those believers in things that they do not even prove whether the belief is reliable. Therefore, in the generation that people are mostly educated, sharks should no longer have to be continuously killed for their fins.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
Such ploys seek to undermine any legitimate eco-consciousness in the audience, replacing it with rhetoric that is ultimately ambivalent toward the health of ecosystems, but definitively pro-business. These tactics assume a rigidly anthropocentric point of view, shutting out any consideration for the well-being of non-human existence; they seem to suggest that nature lies subordinate to our base desires. In addition to upholding the subordination of nature to business and leisure activities, this view establishes nature as something privately owned and partitioned (243), rather than something intrinsic to the world. Our relationship with nature becomes one of narcissism.

Well if you happen to have no idea or clue as into what I’m talking about, which I seriously doubt that’s would be the case. Ever saw the movie Jaws and all of the subsequent directed by Steven Spielberg, then you definitely have a great picture of what the Great Whites are and what they are capable of doing to a human and other sea animal, this also label them one of the most dangerous wild life. The Great White also goes by these other names White Pointer or White Death is from a large species of lamniform shark. If you ever trying to locate on...
Political ecology began in the 1960s as a response to the neglect of the environment and political externalities from which it is spawned. Political ecology is the analysis of social forms and humans organizations that interact with the environment, the phenomena in and affecting the developing world. Political ecology also works to provide critiques and alternatives for negative reactions in the environment. This line of work draws from all sorts of fields, such as geography, forestry, environmental sociology, and environmental history in a complex relationship between politics, nature, and economics. It is a multi-sided field where power strategies are conceived to remove the unsustainable modern rationality and instead mobilize social actions in the globalized world for a sustainable future. The field is focused in political ethics to refresh sustainability, and the core questions of the relationships between society and ecology, and the large impacts of globalization of humanized nature.
A human induced global ecological crisis is occurring, threatening the stability of this earth and its inhabitants. The best path to address environmental issues both effectively and morally is a dilemma that raises concerns over which political values are needed to stop the deterioration of the natural environment. Climate change; depletion of resources; overpopulation; rising sea levels; pollution; extinction of species is just to mention a few of the damages that are occurring. The variety of environmental issues and who and how they affect people and other species is varied, however the nature of environmental issues has the potential to cause great devastation. The ecological crisis we face has been caused through anthropocentric behavior that is advantageous to humans, but whether or not anthropocentric attitudes can solve environmental issues effectively is up for debate. Ecologism in theory claims that in order for the ecological crisis to be dealt with absolutely, value and equality has to be placed in the natural world as well as for humans. This is contrasting to many of the dominant principles people in the contemporary world hold, which are more suited to the standards of environmentalism and less radical approaches to conserving the earth. I will argue in this essay that whilst ecologism could most effectively tackle environmental problems, the moral code of ecologism has practical and ethical defects that threaten the values and progress of anthropocentricism and liberal democracy.
