In 1953, the California grizzly bear was officially designated the state animal of California (State Symbols USA, 1). The irony with this is that the California grizzly bear had been extinct twenty nine years prior to it becoming the official state animal (State Symbols USA, 1). According to the Valley Center History Museum (VCHM), when the first settlers started to explore the western regions of the US, many of them encountered an estimate amount of ten thousand California grizzly bears (Grizzly Bear, 8). VCHM also gives insight over the reasoning behind the extinction of the grizzly bear, citing that the bear was originally hunted to protect the settlers, but this later evolved into hunting it for sport and for its

fur, most likely to be sold for profit (Grizzly Bear, 10). California grizzly bears are not the only animals hunted for both recreation and profit. The rhinoceros is also a species facing extinction due to illegal hunting for their horns. Unlike the California grizzly, these species still have the opportunity to recover. However, urbanization has halted progression for animals to replenish, and has caused animals to migrate to different locations. The relocation of certain species is not only due to urbanization it is also due to climate change. The warming of the Arctic is causing some animals to die off, like coral. Humanity has contributed to the extinction and near extinction of species through poaching, urbanization, and climate change caused by the warming of the planet. This research paper will first address the poaching of rhinos and destructive acts happening to coral. Second part of the essay will talk about urbanization and how it affects rhinos and coral. Lastly will be the effects climate change has had to coral. Poaching has impacted the rhinoceros population tremendously, and is contributing to their rapid decline in population. Rhinoceros have been hunted illegally for their horns, which are in high demand. In Yemen, the horns are used to make daggers called Jambiya, which are given to the Yemeni boys as a sign of manhood and devotion to Muslim religion (Rhino Horn Use: Fact vs Fiction, 2). This tradition is still practiced today, even though the Yemeni government banned the importation of rhino horns (Rhino Horn Use: Fact vs Fiction, 2). The problem with poaching rhinos for their horns is that it has led to the extinction of one type of rhinoceros called the black rhinoceros, which was declared extinct in 2006, according to Time Magazine (Nicks, 2). The resulting effect of the extinction could lead to the endangerment of other species of rhinos. Because of the high demand for rhino horns it would lead to more poaching, and once they are fewer rhinos to get horns from, it could lead to consumers paying more, and as a result of the increase in cost, which would give poachers more of a reason to go after rhinos. Similarly, rhinos are not the only ones dealing with excess hunting, coral reef’ building species are facing similar repercussions. Overfishing of species native to coral reefs have also contributed to their decline, given that coral requires certain spaces to build them up.
One of the causes of overfishing are destructive fishing practices, like dynamite fishing. Fishermen need to figure out better methods of catching fish instead of resorting to the current destructive techniques, such as dynamite fishing, for the reason that current techniques are catastrophic to the coral reefs. Dynamite fishing is a procedure involving an explosion under water, the resulting explosion causing the dead fish to surface (Fishing problems: Destructive fishing practices, 5). This method of fishing can be devastating to coral reefs, as explosions can be unpredictable. Using these current practices shows that humans are indirectly causing the extinction of the coral reefs through their devastating practices of over fishing. With this in mind, some of the motives behind poaching overfishing are largely for self …show more content…
interest. Some people that practice poaching and overfishing do not commit this act because of amusement, some of them do it to feed their families. An article on the BBC gives insight on the motives of the poachers through a film made by a South African filmmaker named James Walsh. People in these communities they see the wildlife as either food for their families or food to sell, and horns are just a bonus for killing them for food (Segendi, 7). To some in the communities, they practice poaching because most of them are unemployed and need some way to feed themselves. Unemployment in Africa is a complication that must be addressed to prevent poaching, and Africa's unemployment is largely due to Africa’s poor economy. Instead of focusing on giving Africans shoes, computers, or books, we should instead invest in Africa's economy to help them create more jobs. This would resolve Africa’s unemployment problem and would decrease poaching. In like manner, Fishermen’s motives for overfishing are also economically influenced. Currently there is a high demand for fish, and on behalf of the high demand the fisherman would have to meet consumer demand to keep their company open. The resulting high demand is causing fishermen to overfish, however, because fishermen are fishing in high quantities, this is leading to an inflation on the price of the fish. According to The Pew Charitable Trusts, commercial fishermen are losing millions in potential revenues by reason of years of overfishing (Sunken Millions:the Hidden Cost of Overfishing to Commercial Fishermen, 1). As a result of overfishing, fishermen are losing substantial revenue, which could lead to them fishing even more as that they could make a profit. The consumers high demand for fish is leading to the death of the coral, as coral need fishes to survive. Corals give insight into the health of the ocean and if the coral is dying, off this is a sigh something is wrong. A solution to the problem would be for consumers to find different alternatives to fish, so that the demand for fish would decline and hopefully give fish a chance to replenish. If the consumption of fish is important to the consumer then they should find a fish a there is plentiful of. Although overfishing and poaching is a problem to rhinos and coral, urbanization is becoming a looming threat as deforestation and urban pollution are affecting their habitat. While poaching is the biggest threat rhinos are currently facing, the remaining rhinos would have to deal with habitat loss caused by urbanization. The WWF reports that in places like India they have to cut down forest to make more room for the population and build more buildings (Rhinoceros, 14). In places like Asia, rhinoceros have been pushed back to smaller areas where there is a smaller population, as a result of urbanization. However, the problem with this is that it would lead to a greater chance of inbreeding (Rhinoceros, 16). This could lead to more diseases, shorter life spans, and a higher chance of developing deformities. The result of urbanization caused by human expansion could very well lead to the extinction of the rhinoceros as they would not have a habitat to stay in. Even if they did, it would be an area with a smaller population resulting in inbreeding. In order to solve this we must find rhinos a large area that is not inhabited by people and put them all in that location. In order to prevent inbreeding we must make sure to keep bringing in any rhinos that are not already located in that region to diversify the rhinos. Correspondingly, coral is also getting affected by urbanization through urban pollution, some of which ends up at the ocean. Another devastating effect people are having on coral is due to urban pollution, ranging from oil to harmful chemicals. According to WWF, over eighty percent of pollution came from land based activities (Marine Problems: Pollution, 2). Oil spills can be a messy problem and challenging to clean up According to a study conducted by the US National Research Council they believe that thirty six percent of oil comes for the drains and rivers from nearest cities (Marine Problems: Pollution, 2). This shows that urbanization is having a negative effect of species. However, it is not just oils that can come from the cities to the oceans. Chemicals also make their way to the ocean in a similar way. When there is a chemical spill near a river, it is most likely to end up in an ocean later to be absorbed by any species it comes near (Marine Problems: Pollution, 15). To solve problems like this we must properly dispose of oil like substances and chemicals and make sure that they are away from water sources. Due to factors like deforestation and urban pollution, this in return impacts the effects of global warming, which greatly affects coral. The process of urbanization has contributed to worsening climate change as chemicals and cutting down trees would have a negative impact to the environment. In places like the amazon, in order to urbanize they have to get rid of trees to make way for the new houses, they do so by burning down the trees (Climate Impacts: rainfall and temperature, 3). According to the NASA Earth Observation, sciences believe that the amazon has ten years worth of carbon produced by greenhouses (Climate Impacts: rainfall and temperature, 3). By burning down the trees in the amazon this would release the carbon into the atmosphere which would enhance the effects of climate change. Again, action like burning down forest causes the earth to get warmer and impacts greenhouse gases. Humans have contributed to climate change immensely, especially through the burning of coal, which releases CO2. The cause of climate change is due to a rise in greenhouse gasses, like coal, which is the main cause of climate change. Coral reefs have taken a huge blow over the years as a result of climate change by cause of the change in temperature of the water and the loss of its reef building species (Dell'amore, 16). The Great Barrier Reef has seen a massive die off of the coral. According to an article in The New York Times, the reasoning behind the mass die off of coral is of the resulting warming of the ocean, which is bleached and weakening the coral resulting in their die off (Innis, 1). Humans that are using coal for energy are causing the temperature in the ocean to rise, therefore they are contributing to their extinction of coral. To keep prevent global warming becoming worse we must stop burning down forest, instead of burning them down people should cut them down by hand, which would in return create more jobs. We must invest in alternative energy sources like solar or wind power, so that people would no longer burn coal for energy. Humanity is having a profound effect on wildlife whether if we know it or not.
Poaching and overfishing is a big problem that we are facing. Some people do not like to poach, for they poach just to stay alive. Fishermen overfish because a combination of decreasing profit and high consumer demands. This shows that people rely on these rhinos and fish to be able to put food on the table, it shows that we need each other. Nature is like jenga if you take one peace we could all go down with it. The process of urbanization is greatly affecting wildlife through deforestation and urban pollution. Deforestation is causing the loss habitats and urban pollution is causing damage to the ocean, which in return also affects climate
change.
Nature, it is everywhere, everyone uses it. Quite often, however, people abuse it, such as with humans’ impact on grizzly bears. Grizzly bears are important to the environment because they have many useful purposes for the environment: “they provide an “umbrella” for the environment because they require such large home ranges.” (savethegreatbear.org/CAD/Grizzly.htm) The Grizzly Bear is extremely vulnerable to changes in its habitat and food cycle. This allows humans to detect small changes in the environment, just by watching this amazing species. The Government of Canada needs to try harder to stop the poaching of grizzly bears in Canada.
The wolves’ were hunted in late 1800 s’ and early 1900‘s in the United States because farmers wanted more land for their cattle’s to graze upon. As farmers were moving out west they felt threaten that the wolves would hunt their cattles so the farmers thought that the best solution would be to take them out of the picture. This was possible because at the time there were no government regulations on hunting....
Many people who hunt the limited Grizzly Bears do it to satisfy their own “needs” of achievements. The Grizzly bear is an exclusive species that is only local to British Columbia; therefore it adds to the feeling of achievement for hunters, but it also encourages individuals, environmental organizations, and the first nations to preserve this rare species. Hunting bears is not sustainable and it’s much worth it to have them alive to promote more advantageous benefits than to have them dead with their heads on the wall to amuse people or to disturb people’s thoughts of what was once a beautiful
1914 began the official war of the wolves. This year Congress officially approves funds for the eradication of wolves, cougars, and other destructive animals. Wolves were declared destructive to agricultural and big game interests and formally hunted. Nearly a century later, in 1995, wolves were reintroduced to Yellowstone National Park and Idaho's Frank Church-River of No Return Wilderness(Phillips, 1996, p.20). The reintroduction of wolves in Yellowstone National Park did not end the debate of whether wolves should stay or go. Advocates for wolf reintroduction say the wolves control elk and deer population numbers; preventing the destruction of ranchers cattle and the land. Opponents say the wolves kill elk and deer that could be hunted. Ranchers fear the wolves will kill their livestock decreasing profits.
Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended species. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of the chain depends largely on the interaction between the predator and the prey.

Environmentalists call this problem the Urban Deer Dilemma. This exists when the number of deer exceeds the ability of the environment to support the deer (2). During the 1600s, when Jamestown’s first settlers arrived, there were between 24 and 31 million white-tailed deer in North America (4). As settlers pioneered farther west, the deer population steadily decreased until a dramatic drop in the 19th century. By the end of the century, less than half-a-million deer were left. In some parts of the United States, there were none. In 1886, the US Supreme Court forced hunters to get licenses and follow certain restrictions. Conservationists urged hunters kill bucks instead of does. Because of these precautions, by the 1940s, 30 states in the United States had deer herds large enough to starve themselves (4).
Overfishing is a major problem in economy today. The practices of fishing too much or too often result in a decrease of the fish population. Constant removal of fish from the oceans (fishing) accounts for both adult and baby fish. With the consistent decrease in adult fish, mating becomes more difficult or even impossible, resulting in an overall lack of fish in the oceans. Pepijn Koster defines overfishing as, "Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans." (par.1). When fish stocks cannot be replenished faster than they are being depleted, a reduction in fish population occurs, which is what is referred to as overfishing.
In recent decades, the global warming threat has captured the attention of the nation and the world. While the main focus began with concentrating on the effects this long-term natural crisis would have on the human population, select groups have worked to approach the topic in a manner that entails prevention in order to help other animal and plant species around the globe. One such organization is the National Oceanic and Atmospheric Administration, which has played a major role in the conservation of the polar bear species, one of the mammals most adversely affected by the recent climate changes. As more research has been conducted regarding the polar bears, scientific name Ursus Maritimus, the conclusions have been shocking. In 2008, the Department to the Interior listed the polar bear species as “threatened” under the Endangered Species Act of 1973 awarding it some protections mandated by the federal government (Wolfe). However, on January 5, 2011, Representative Donald Young proposed a bill in Congress in order to delist the polar bears as threatened, thus decreasing and even removing the conservation efforts that have been set in place over the past three years. The polar bear Species should remain listed under the Endangered Species Act because ice thickness has decreased 40 percent during the past 30 years thus reducing the polar bears’ critical environment, if current conditions continue the polar bear populations around the world may decrease by two thirds by mid century, and since the species has been protected under the Endangered Species Act the worldwide populations have experienced stabilization or growth in most circumstances.
Over a century ago, humans fought animals for dominance of the landscape and we regrettably won, now they’re in need of our protection. The Government and Organizations have come to the rescue of wildlife species all across the U.S. Their main goal is to protect wildlife species from over harvesting and also their loss of habitat due to industrial and residential development. The beauty and curiosity of wildlife captivates all of us for different reasons. For certain species, they are the link to our existence Animals are not being hunted into extinction because the government is protecting certain wildlife areas and are controlling the animal populations within those certain areas. While increasing a wildlife species population and removing from the endangered species list, a predator such as the gray wolf, is sure to be seen as a success to some and a threat to others.
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
Poaching is only one of the leading causes for animals being on the endangered species, so with all these poachers we need to protect the animals more closely. Animals that are close to extinction need to be placed into a zoo or sanctuary so they can flourish. People need to do this for the animals, they may not like it but it helps get their numbers up.
Everyone’s all seen those wildlife shows on tv. The shows on National Geographic and such, showing animals in beautiful environments, everything lush and growing and nothing at all wrong that could threaten these creatures and places. But, have anyone seen the other side? The side where all these beautiful creatures and plants starve, are decimated by predators that have never been there before, and sometime even become poisoned by their very own homes and habitats? Of course no one has. That doesn’t mean that its not happening. It is happening, and its happening everywhere. And guess who is to blame? People. Society. Humans as a race pollute the environment, hunt animals simply for their parts, fish way more than humans will ever need just for the sake of money, introduce new species to new places for our own gain, and even purposefully destroy entire regions just for human expansion. And its starting to take its toll. While it is true that nature is constantly in flux and certain species come and go, humans are causing more species to disappear in the past few hundred years then nature has ever caused since the age of the dinosaurs, and therefore it is up to humans to repair the damage caused, be it cleaning the environment and habitats of these creatures, or taking more direct action to protect and preserve the species that are on the brink of extinction.

Although it may not seem saving or protecting endangered animals is important, it actually and truly is important because animals around the world are being killed for wildlife market goods which is illegal and destroys the species population in that environment. Citizens should take more concern with taking care of these endangered animals before they become totally extinct and will no longer be seen on the face of the earth. Recently researchers have found that poachers (hunters who hunt animals for their value with trading illegal merchandise) are killing thousands of animals a day, and they are doing so even to this day. These species should be treated with more responsibility and care. They are even being killed by human interactions
