Recommended: Essays on animal extinction
The extinction of indigenous animals has been an ongoing problem that has not received the attention it deserves. Biologists have studied the pattern of mass extinction with growing concern. The world’s species are declining at a rate 10,000 times faster than normal according to a census of the world’s species (Dugan). What is causing such a rapid increase in extinction is unknown however there is one thing that is indisputable: human interference is playing a direct role.
Poaching is the illegal hunting, killing or capturing of animals. Poachers sell the animals as pets, foods, and fur. During the 1960s jaguars, leopards and tigers were poached for fur and meat. The animals organs and meat were then sold as aphrodisiac medicines and the skin was used for making accessories. During the sixties and seventies, around 18,000 jaguars were killed every year for their beautiful coat. Formerly prized furs, such as those from the leopard, cheetah, or jaguar, may no longer be hunted in the countries where they are indigenous, and many other countries forbid their importation (Miller). Another example of an animal being hunted to near extinction is the whaling industry in the 19th Century. Southern Right Whales were hunted because they float when dead, can yield, many barrels of oil, have long baleen plates and come close to shore. Whale oil was used for candles, light fuel, soap, heating and lubricant. Baleen or “whalebone” was used in corsetry, bookbinding, whip, and umbrella making (Environment). Between the years 1835-1844 whales in New Zealand and Australia were hunted to near extinction. As a result the hunting whales was no longer profitable and by 1935 the whales were internationally protected through the League of Nations and b...

...d the economic, ethical, and practical aspects of international regulation. Different views of ecology, culture, and legitimacy as they pertain to a valued resource and its exploitation for human purposes. While it is safe to say one must preserve the historical and cultural value of whaling nations and nations around the world, it can also be said of animals. While many nations continue to cling to their cultural ancestry background of whaling and the right for scientific research, it is proven that such human endeavors must be carefully and faithfully regulated. Commercial whaling has essentially seized to exist in the clear claims of such, but Japan and other nations are ever so slightly getting closer to that boundary. “We should remember in our dealings with animals that they are a sacred trust to us…[They] cannot speak for themselves” (Harriet Beecher Stowe).

Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must be taken immediately!
Years ago, species such as the Pyrenean Ibex, Passenger Pigeon, and the Wooly Mammoth used to roam the very same earth that we humans walk today. These species, along with many others have gone extinct over the course of time and now only fossils remain. However, Scientists are using biotechnology in an attempt to bring these species back from the dead. This process is known as de-extinction. De-Extinction, also known as resurrection biology, is the scientific process of resurrecting species that have died out, or gone extinct (Britannica). Scientists are using three different techniques in their attempt to resurrect these species which includes breeding back, genetic engineering, cloning.
Killing for Conservation: Recently, “poaching” has come under a harsh light. With the killing of Cecil the lion in July, animal rights activists have been fighting for an end to big-game hunting. Walter Palmer, a dentist from Minnesota, has come under fire for the illegal baiting and shooting of Cecil. Although illegally done, what Palmer did wasn’t technically poaching. To poach is to “trespass, especially on another’s game preserve, in order to steal animals or to hunt” (“poach”).
Scientists in Great Britain have been studying the distribution of birds, butterflies and plants for the past 40 years and the results from these studies suggest that the Earth is heading towards another mass extinction, and this one may have its roots in human activity.
De-extinction is a process that has been experimented with for many years, but has never been completely successful. The ethics and consequences of this idea have been questioned but, de-extinction has the potential to be truly helpful to humans and the environment, and many of the scenarios that people think could happen, are actually impossible. To actually revive a species, there are certain conditions that must be met, and the terrible situations that people think could happen, are unable to actually occur because of the lack of . Bringing species back that are beneficial to the environment could preserve biodiversity, restore diminished ecosystems, advance the science of preventing extinctions, and undo the harm that people have caused in the past. The true potential of the revival of species cannot be realized because people overdramatize the effects and possible outcomes. Once we realize and understand how beneficial the process of de-extinction can be we can better improve our world, our lives, and our ecosystems.
The 1992 Convention on Biodiversity (CBD) conceded that the eminent adversity threatening biological and resource diversity is a global calamity. Pertaining to biodiversity alone, studies have revealed that about 1.4 million of all known species (comprising of 26.96% of flora and 73.04% of fauna) are in existence globally (WCMC, 1992; Bhargava, 2006). Despite the rich biological diversities, there are manifestations that, these global diversities are constantly disappearing at quite an alarming proportion. Biodiversity levels are projected to be deteriorating across the globe with about 25% of all mammals threatened by extinction in the next three (3) decades (Yelfaanibe, 2011). Some scholars have advanced reasons responsible for the failure
As humans pollute the Earth on a daily basis, some want to de-extinct animals—bringing back animals through scientific processes—however, results of this would be unpredictable and costly. De-extinction has many pros and cons. For instance, de-extinction is beneficial because it lets us study more about how those animals lived and, in a way, be payback for our reckless and unthoughtful actions back then. Yet, it can be consequential because the process costs much more than current attempts to protect endangered species, and there is no assurance that the process will have a positive outcome.
== = = Human beings are dependent on the Earth's diversity of species for our survival. Wild species play a vital role in the maintenance of the planets ecological functions, yet everyday on the planet 40-100 species become extinct.
...restation, rising sea levels and species extinction. It is imperative to look at both sides, in not all sides, of the story and its real effects at the level of the individual if a real understanding of issues is to be developed.
Whaling is seen in the international community as a cruel act to animals. The reasons behind whaling varies; from its meat consumption to its use for medicine. Unfortunately, the international ban on commercial whaling, it has not abated the act by some countries such as Japan and Norway. In addition to Iceland, Japan and Norway killed 2,000 whales each year (WDC, No Date). As the whaling continues, its effect becomes obvious in the population of the whales.
Every day a whale is killed for food and/or for science. The International Whaling Committee (IWC) has made a rule against commercial whaling, due to the major decrease in whales over time. Whales have begun to become extinct. Commercial whaling is now illegal unless it is for scientific purposes only, but it is also open for societies who whale due to their culture. Multiple countries have used the regulation of ‘scientific research’ as a loophole to advance on the practice of commercial whaling.
Poaching is the illegal killing of animals. Many animals, especially elephants are poached by hunters all over the world. Fewer than 100 years ago, millions of elephants lived on Earth. Today, there are less than half a million. Elephants are poached for their tusks made of ivory which is sold and traded all over the world. Poaching has been made so popular that the lives of elephants as a species are at stake. Elephants are endangered because of the effects of elephant poaching.
The Earth is far and away the most biodiverse planet in our solar system, with about 8.7 million more unique species than the other 8 planets (UNEP). However, the Earth’s commanding lead is shrinking; not because the other planets are increasing biodiversity, but because Earth’s is decreasing. According to the World Wildlife Fund, we as a planet are losing 1,000 to 10,000 more species than the natural rate. Since the total number of species is hard to pin down, this can mean anywhere from 200 to 10,000 species going extinct per year (World Wildlife Fund). This obscenely high extinction rate is dangerous not just to ecosystems directly affected by the loss, but also creates a domino effect that circles around the globe and up and down the food
