The Extinction Of Species Extinction

John Wiens, an evolutionary biologist at Stony Brook University in New York says, “There is a terrible urgency to saving threatened species and habitats.” He continues in saying “As far as I can see, there is little urgency for bringing back extinct ones. Why invest millions of dollars in bring a handful of species back from the dead, when there are millions still waiting to be discovered, described, and protected?” This is a problem for many scientists and Paul R. Ehrlich states in his article, The Case of De- Extinction:It is a Fascinating but Dumb Idea, says that “It is much more sensible to put all the limited resources for science and conservation into preventing extinctions, by tackling the causes of demise….” This is proving that de-extinction is a bad idea because of the facts that it is more important to put money and research into conservation efforts. By focusing on de-extinction. We are tearing away our focus on these efforts and putting it into something that may or may not work. Something never tested that could possibly hurt not help the environment. Paul R Ehrlich also states that “De-extinction seems far- fetched, financially problematic, and extremely unlikely to succeed.” With de- extinction hindering conservation efforts and being unlikely to succeed it is clear that we should not even attempt de-extinction. However hindering conservation efforts is only one way that de-extinction is a bad

Humans have caused another extinction, one that could possibly take us down in the process, species are exponentially going extinct because of habitat loss, species exportation, and invasive species bullying native species. On the other hand, scientists are trying to safe guard native species, keep animals in captivity whether it be for the animals well-being or for research, and widespread invasion. In this essay I will be comparing and contrasting “What Everglades Pythons and Other Invasive Species are Trying to Tell Us,” by Julia Whitty and “The Sixth Extinction,” by Jeff Corwin.

The scale and pace of change is dramatic; for example, the extinction of species is occurring at around 100-fold pre-human rates4. The population sizes of vertebrate species have, on average, declined by half over the last 45 years5. More than 2.3 million km2 of primary forest has been felled since 20006. About

Many species vital to ensuring that today’s environment will thrive are becoming extinct. If a species is slowly dwindling, and in imminent danger of becoming nonexistent, this species is considered to be endangered. “One in four mammals, one in eight birds, one third of all amphibians and 70% of the world’s assessed plants on the… IUCN Red List are in jeopardy” (IUCN, 2016). According to the International Union for Conservation of Nature, or IUCN, upwards of 16,000 species are threatened with extinction, including both plants and animals (IUCN, 2016). Before becoming endangered, a species will show warning signs, either by starting to lose biological diversity or by losing the habitats for that species to flourish in, or in the worst case, both. The word endangered can sometimes be confused with threatened, extirpated, or extinct. Extirpated refers to the state of a species where its population has died out in a certain area or range, but other populations of said species still exist elsewhere (Olden, Julian D., 2008). When a species is considered threatened, or vulnerable, this refers to the state of the species being susceptible to endangerment and extinction (“Extinction crisis escalates”). So if a species is threatened, the first signs of endangerment come along, which are similar signs to that of a species in danger of becoming threatened, including lack of genetic diversity, or overhunting may be evident. (“Extinction crisis escalates”). When a species is labelled

The advent of functional analysis (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) and functional assessments (Dunlap & Kern, 1993) have provided behavior analysists with great ability to provide effective treatment for their clients. One common topic of research is the treatment of escape-maintained behaviors.

Conservation of our biodiversity not only demonstrates foresight, it protects the natural resources so vital to our own continued existence. The value of any single species to an ecosystem is immeasurable; the environment will not endure without its species, despite size or niche. These animals are not dispensable. And, they are apt to face extinction in the not too distant future, unless a resolve for their preservation is insisted by the public and enforced by governments internationally.

Extinction: A Radical History is a book published by writer, professor and activist Ashley Dawson. It was published on the 22nd of April 2016. Dawson talks about multiple broad subjects in his book like how Capitalism is the main source of mass extinction. By doing so, he takes into account the lengthy history of the Homo Sapiens species, their activities and their discoveries and how us, humans, have affected today’s biodiversity, and probably the future of our planet Earth. He also offers solutions but are they realistically possible? Today, we no longer face natural risks like asteroids and comets. As Dawson states we now face anthropogenic risks like climate change and biodiversity loss which leads to a change in the earth’s ecosystem.

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

In a summary, Kolbert explains the extinctions of a variety of different major animal species that became extinct. She also explains that if trends in the environment continue that the biggest extinction in history will occur soon. If global warming, deforestation, and glaciers continue to melt she says that more and more species will continue to become extinct. She explains how humans need to be more conservative and careful with what they’re doing to prevent extinction.

Initially, like some teenagers in my class, the interest in genetic engineering was nothing more than a fad. My classmates would chatter for a few moments about the subject of de-extinction. But, the topic disappeared into the background, replaced by pure middle school gossip. However, there was something about the concept of de-extinction that intrigued me. And, as the notion sunk in, the ideas began to flourish.How did they bring the animal back? Could we bring back other animals? Would they be different from their older counterparts? As my internal monolog of questions grew, I sought my mother for help. When asked, she stated one word,”Write.” With a smile on her face, she knew that I had begun to discover an interest. With my mother’s advice

A clear analysis shows that extinction has occurred so much, that they do not only list the animals, they have to list a broader and more general title, meaning extinction is so worst that writing the names of the animals' name will be too much, and writing the whole broad title will include thousands of animals under one title. With 41% amphibian, 26% of mammal species and 13% of birds. It is extremely alarming. And the extinction only includes the species that has been found and labeled by us, there are much more species that have not been discovered if any of those species goes extinct we would have never known they existed in the first place. The fact that the sixth extinction is compared to the mass extinction of wipe out that happened

Biodiversity is the variety of plant and animal life in the world or in a particular habitat, a high level of which is usually considered to be important and desirable. Slowly the Earth is changing because of climate change and biodiversity is very important now to ensure that a rapid loss of animals doesn’t affect the way the world will grow in the future. In this report the issues of extinction will be discussed along with an example of an extinct animal called the Diprotodon optatum. Sustainable practises, such as recycling, help to prevent the extinction of animal and plant life all over the world. This essay will argue that the prevention of extinction of animals is essential to ensure that the biodiversity of the Earth is sustained.

Since the beginning of life itself, some species have lived and prospered while other species have gone extinct never to be seen again by mankind. Because of this, some would claim that extinction is natural and not significantly problematic to the world that we live in. Others, however, understand that due to climate change, habitat loss, and poaching, more and more species are becoming endangered which leads to a chain reaction that can be devastating to ecosystems. Species such as the Chinook salmon, gorillas, tropical sharks, and polar bears are all directly affected by climate change, species such as northern spotted owls, Sumatran tigers, and lemurs are greatly harmed due to habitat loss, and species such as the sea turtle, Javan rhinoceros, African elephant, and the Red-Fronted Macaw are all affected by poaching driving them all closer and closer to becoming extinct.

It’s clear that a great extinction is coming from the evidence of the destruction of other species around us. The choices made by the human race have too often negatively affected the surrounding species. Tracy Wilson, the site director for HowStuffWorks.com, in an article for Animal Planet, states that

Policy- and decision-makers claim information about the causes of population declines which driving species on the brink of extinction (). However, it is pointed out that the causes of vulnerability remain unclear to explain the variation to the risk of extinction (). According to Reynolds (2003), vulnerability is determinate by both the decline of species population and the reduction of their geographical range. These two forms of vulnerability are affected by both species’ mortality and habitat loss, which are the causes of intrinsic biological traits, extrinsic human induced effects and stochastic factors that likely determine the population trends (). It is suggested that extinction risk is not distributed by chance between taxa,
