Stuart Pimm offers a degree in Conservation Ecology from Duke University. His Argument focuses largely on humans are not ready for De-Extinction in that since humans were the ones that pushed them to disappear, they are not going to want those species back. He gives the example that “hunters at [the Pyrenean ibex] to extinction. Reintroduce a resurrected ibex to the area where it belongs and it will become the most expensive cabrito every eaten.” He notes that the problem is whether we can resurrect these species or not, but more along the lines of whether the rest of the population will accept the animals back in their original homes. He also believes that De-Extinction “seduces” those granting research money and support into thinking they are doing well when it simply gives “unscrupulous developers a veil to hide their rapaciousness, with promises to fix things later.”…

To go through with this, it would cost an arm and a leg, just to try and resurrect something, and it may not even work. As it said in Back From the Dead, even if it did work, they could become invasive and harm other living species. In Sarah Zielinski’s article, De-extinction probably isn’t worth it, she said it could harm up to 14 currently living species. In an article by Breanna Draxler, she told us that some of the extinct species could bring back retro diseases. Would you risk up to 14 species dying, just for one more species to be…
The possibility that mammoths, passenger pigeons, saber-toothed cats, and thylacine may roam the very earth our feet stand upon once again is a thrilling, yet apprehensive thought. Carl Zimmer proposes this very idea in his essay “Reviving Species” and gives feedback on the topic of de-extinction. According to Zimmer, de-extinction is defined as, “The notion of bringing vanished species back to life”, and he elaborates the pros and cons of actually completing this ordeal (31). Reading the differentiating views on the subject is very interesting, and caused me to think more and more as to if bringing back the extinct species is for the good or bad of our world. But as a firm believer in Christianity, I feel de-extinction is a sensitive subject and is “… playing God.”, especially if…
“The issue should never be about the extinction of any animal, it should always be about the cruelty and exploitation which will lead to their extinction,” unknown. Each and every animal on earth has as much right to be here as you, me, and of all humanity. Scientists have found a way to clone extinct species. The thought of that sounds amazing and really exciting, but think about it another way. If we bring back no longer existing animals, us humans will do what we do best, which is changing nature and destroying it, basically killing them for money or being greedy for food. According to text “no,” there are already many living things becoming extinct many times faster than normal. Why would we worry about animals who are already long gone when there are many other things that are important to the environment that we need to care about? Another reason why we should not bring them back is because our Earth has changed significantly since they were alive. Having them back would change many things. Lastly, education costs lots of money.…
The process of de-extinction or resurrection biology is in simple words, “the process of resurrecting species that have died out, or gone extinct” (Encyclopedia Britannica). While it may sound like a simple idea, it is anything but that. Stewart Brand, a professional environmentalist and futurist who is leading one of the biggest de-extinction projects, explains that there are three semi-successful techniques to…
While one tends to have the general idea as to what’s happening around the world, it isn’t until someone comes around and tells you exactly what’s going on that you become truly aware. This thought was the first to cross my mind while I was reading The Sixth Extinction: An Unnatural History by Elizabeth Kolbert. Before getting into the details of this book review, I would like to preface it by saying that before beginning this class I had an idea of what was happening around the globe. I was not so uninformed as to say that I didn’t know the climate was changing and species were gradually disappearing, but rather I was unaware as to just how quickly this was taking place. I can say that in the back of my mind there has…
Conservation is the practice of protecting plants or animals, and their habitats. These plants and animals may be very close to extinction. North America experienced a big loss of megafauna at the end of the Pleistocene era (about 13 000 years ago). This started a program known as “Pleistocene re-wilding”. Re-wilding involves the reintroduction of extant species into areas where they became extinct in the past. This program aims to restore the evolutionary and ecological potential that North America lost all those ago, and in the process, prevent the extinction of the megafauna in Africa and Asia. This caused many opinions about North American re-wilding to form. The two main papers that will be discussed are Donlan et al, 2005 and Rubenstein et al, 2006. Both of these papers express different opinions.…
For over 150 million years, dinosaurs dominated Earth. They were incredibly successful-so successful in fact that all of the other animal groups had no choice but to play a secondary role in nature. 65 million years ago, however, every species of dinosaur went extinct as well mosasaurs, plesiosaurs, pterosaurs, ammonites, and many families of brachiopods and sea sponges. Also, many shark species as well as most vegetation did not survive(“Dinosaur Extinction”). What could have possibly killed off the dominant animal group of the time? The answer to this question is still unclear but there are many hypotheses that attempt to explain this extinction event. To find out exactly how this happened, evidence must be gathered not only from fossils…
In many opinions, invasive species becoming introduced to a different environment is not deemed acceptable. With many situations incorporating these species, they are sought to be pests, only trying to make lives difficult for others. Many also have come to believe, from experience, that these insidious species cause harm to the environment of which they are newly exposed to. The businesses and/or government agencies that bring invasive species to a new environment must consider many measures before transferring and following through with brings the species forth to a new location. With careful considerations of transportation, other natural predators, the actual environment and the sole purpose, the business and/or government agency must vigilantly take into consideration the actions it is about to partake in.…
De-extinction is when someone creates an organism that is the same or similar to an extinct species. Cloning has been the most common that scientists have been trying to achieve. Some of the animals that they are trying to bring back are the passenger pigeon and the woolly mammoth, they plan to do this by extracting DNA fragments from preserved animals they have. Cloning only can work if they…
An invasive species such as the zebra mussel, invaded the Great Lakes of America in 1988. They were brought in by seagoing vessels that emptied their ballast water as they got in the port, the zebra mussels had hitched a ride in the water taken in in the ballast before the ship left port in the Caspian and Black seas. By 2010 these muscles and colonized the waters in over 30 US states spreading like wildfire. Invasive species have a huge impact on their nonnative environment, the zebra mussel clogs and take pipes at factories in water treatment facilities that can degrade docs and ruin fishing gear. But it’s not the only invasive species after reading this chapter I decided to look up a little more online about invasive species, it seems that…
Humans have contributed to the problem of invasive species throughout history according to, "The Snake That's Eating Florida!", by Lauren Tarshis. First, people have done this by getting burmese snakes as pets and then releasing them into the wild. This means humans put them into the wild were they could become part of the ecosytem there if it didn't die. Also, another way humans have contributed to the problem of invasive species is when Christopher Columbus brought wild pigs to the Carribean and then the pigs went to Florida also; some of these pigs got lost in the wilderness forever. There are now 2.3 million wild pigs in Texas that cause a lot of damage. This means that if Christopher Columbus didn't bring wild pigs to the Carribean, Texas…
“Once an invasive species arrives, it’s about impossible to get rid of it,” - Sean Hanna. There are many animals that create problems. An invasive species is an animal or a plant that is brought into a new environment and damages the animals and plants that live there. There are many invasive species today such has the Burmese python, starling, and the red fox. Invasive species are a problem and there is many ways that the problem is being addressed.…
