LARGE PREDATORS MANKINDS FIRST ENEMY In the history of humankind, the extirpation of predators has always been at the top of the priority list. However, no one ever thought of the backlash it would have on the environment. Large predators have always been looked at as the enemy of man people have learned to fear these remarkable animals that they were directly competing with for resources and survival. The decline of large predator populations has caused ecological complications all over the world (Weber and Rabinowitz 2010). From tigers and wolves to fishers and orcas, the human species has extirpated these primary consumers for economic development, safety, and hunting preference (Weber and Rabinowitz 2010). In the past, these actions were encouraged, but as recent ecological studies have shown these top predators have proved to provide a necessary balance to ecological hierarchy (Beyer et al. 2006). …show more content…
But even with this new information predators, especially large carnivores are still perceived as monsters or nuisances by many people who have led to major population declines throughout the world due to lack of education and irrationally biased hatred (Williams et al. 2002). Human-wildlife conflicts have shaped the way people view these predators, and strong economic incentives lead to illegal hunting and trade. Ecological sciences have been telling the world to reconsider what we have always thought about large carnivores and to realize that they may be the key to maintaining sustainable, healthy ecosystems. However, it has taken a lot of strong-willed conservationists such as Alan Rabinowitz to push people to realize that most of what people know about the predators is wrong and that ignorance will continue to destroy our
Man is responsible for the extinction of the North American megafauna (Donlan 2005, Rubenstein et al. 2006). Since our ancestors are responsible for the extinction, it’s our duty to fix what our ancestors have destroyed (Donlan 2005). Moreover, according to Donlan (2005) most megafauna species in Africa and Asia are endangered or under threat. Hence, relocating them to North American is a best way of conserving them because the country carries “Global conservation implications” and contrary to that Africa and Asia practice poor conservation strategies (Donlan 2005). He further argues that N...
Rapidly evolving throughout the late Pleistocene to the early to mid Holocene, hunter-gatherer-fisher societies hunted megafauna creatures in a systematic and ethical way. When one species migrates to a different ecosystem, that species is not usually recognized as a threat to other species. Survival, during the late Pleistocene and Holocene era, was one of the most important aspects to life. Any organism, regardless of size, living within their environment had to stay alive and reproduce. During these two eras, it seems...
In the last decade, from the Rockies to New England and the Deep South, rural and suburban areas have been beset by white-tailed deer gnawing shrubbery and crops, spreading disease and causing hundreds of thousands of auto wrecks. But the deer problem has proved even more profound, biologists say. Fast-multiplying herds are altering the ecology of forests, stripping them of native vegetation and eliminating niches for other wildlife. ' 'I don 't want to paint deer as Eastern devils, ' ' said Dr. McShea, a wildlife biologist associated with the National Zoo in Washington, ' 'but this is indicative of what happens when an ecosystem is out of whack. ' ' The damage is worse than anyone expected, he and other scientists say. Higher deer densities have affected growth, survival, and reproduction of many plant species which have aesthetic, economic or ecological value. In some cases, many species of trees have also been shown to have reduced growth as a result of high deer density (Environmental Benefits of Hunting, 1). Deer prefer certain plant species over others and frequently feed on economically valuable tree species. For example, they prefer oak and sugar maple seedlings, as well as acorns, over less palatable species like American Beech and striped maple. Thus, less marketable species are more likely to survive to maturity,
Flocken endorses that “...hunters are not like natural predators.They target the largest specimens; with the biggest tusks, manes, antlers, or horns.” In Defense of Animals International (IDA) argues that hunters concentrate on“game” populations and ignore “non-game” species that may lead to overpopulation and unequal ecosystems. Therefore, it affects their ecosystem, and the animals’ families. Overall, the evidence proves trophy hunting hurts the environment, specifically conservation. Therefore, the hunters’ idea that trophy hunting actually helps conservation by killing some predators to maintain balance, is merely
For years tigers have been a symbol of grace, power, and majesty (“Tigers Threatened,” 2006), exhibiting mesmerizing beauty and limitless strength that has been recognized throughout the world. Because of this, tigers are highly valued, as their body parts are prized and worth an enormous fortune, consequently resulting in 3 of the 8 subspecies of tigers into extinction (“Tigers Threatened,” 2006). The remaining five tiger species went from hundreds of thousands, to only 3,000 – 5,000 combined, and one subspecies has been targeted tremendously for their prestigious status. In particular, Amur commonly referred to as the Siberian tiger, now face a great deal of danger, as poaching increases and destruction of their homes persist, leaving Amur on the brink of extinction as well. With approximately 500 left in the wild (Sartore, 2014, p. 1), the imperiled mammals status signifies severe endangerment, where recognition and assistance are in desperate need to put an end to prohibited hunting, and mindless deforestation. The following paper will incorporate aspects of both hunting and destruction of the ecosystem, as they are the two driving forces causing rapid tiger demise.
Thousands of years ago, hunting may have been the cause of the extinction of the North American large land mammals. “Moving up into the 1940’s and 50’s some of today’s most prominent game animals were almost non-existent.”(Kerry G) Over-hunting will directly cause the decline in the particular animal’s species. This will effect everything around it, for example ...
Predators: Strange Days on Planet Earth is an interesting video about predators’ effects on their ecosystems. The video found on Films on Demand describes how many ecosystems across the world are in danger because of the lack of predators. Venezuela’s Lake Guri is in chaos because beasts of prey have long since fled because of a flood, and now, herbivores are overpopulated and have depleted resources. Yellowstone’s Aspen tree problem seems to have started with the killing of wolves and has gotten better when wolves were brought back, allowing less elk and more plant life. Jamaica and other places near the sea have seen their fish disappearing, along with their coral reefs.
Maintaining predator access to prey is essential to a healthy and normal ecosystem. After years of damage to the ecology, in 1999 wildlife corridors were reconstructed to reconnect predator with prey. “As exciting as it is to see animals living in their natural environment, it is essential that we keep the ‘wild’ in wildlife and maintain a healthy human to wildlife relationship”(Faye Baldock, (2018) The Real Banff
The. In 1995, the number had been reduced to around 64 million. Within 20 years, in short, the duck population was reduced by almost one third, showing. the drastic toll hunting is taking on our wildlife. If we assume that other species have been reduced in number at approximately the same rate in recent years, then what are the larger implications for our ecological balance?
Wildlife has been living alongside man for as long as our species has been a part of this world, and the wildlife has even been here longer. You’d think that with man and animal coexisting in each other’s presence we’d respect the wild species that we have now a lot more than we do. Many people, whether they’re aware or not, are slaughtering animals all the way to extinction, and there are definitely more ways than one that humans are partaking in the extinction of endangered animals. We have to clean up our act before it’s too late for these animals, including us.
The predatory behavior of animals is of such value to natural selection itself that human beings are now attempting to reach back to primal roots to benefit from predatory, animalistic instincts. The U.S. military is currently experimenting with the somewhat lofty prospect of updating drone technology based on the behavior of falcons. These predatory instincts, though, are the product of what experts call dominance hierarchies in the animal kingdom, and these hierarchies are socially reflective of those historically observed among human nationalities, ethnic groups and religious groups. Individuals within any animal population may be inclined to dominate the population and its ecosystem by monopolizing both resources and sexual partners.
One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct. Organizations like the “World Wild Li...
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.
The degradation of ecosystems and loss of biodiversity is increasing at an alarming rate every year. Humans are certainly not the only reason for this, but they are the main contributors. The well-being of ecosystems affects our everyday lives - consumption and consumerism depend on natural resources. Everything humans use is derived from them, in seemingly indirect and direct ways. Yet despite the fact that humans are destroying the environment, many continue to and neglect to take important measures to protect it.
It is known that the world relies on capital. Without it the economy would collapse leading to war, famine, and death. Wildlife is an integral part of the world's economy. The world's populatio...
