Extinction Of Species Essay

Biodiversity is vital to the survival of an ecosystem. However, the increase of extinct and endangered animal and plant species has weakened the diversity and sustainability of the ecosystem. Human activity is the leading cause of the high extinction rate of species; about ninety-nine percent of endangered species are at risk due to human activities (biological diversity). However, humans do not think what we are doing to the environment is immoral. Why do humans act like everything we do is morally

Extinction is the end of an organism or group of taxa.  Extinctions occur when a species becomes unfit for survival in its natural habitat usually to be replaced by another, better-suited species. An organism becomes ill-suited for survival because its environment is changed or because its relationship to other organisms is altered as stated from Credo Reference. The moment of extinction is generally considered to be the death of the last individual of that particular species. Mass extinctions, however

Sixth Extinction: An Unnatural History in 2014. This is a non-fictional account of what Kolbert had named "the sixth extinction": an extinction event caused by humans similar to ones that destroyed earlier forms of life, like the dinosaurs and megafauna. Chapter One details the ancestry of frogs and examines the timeline of amphibians on Earth, as well as the increase in frog extinction rate. Kolbert argues that the observed extinction rates which are exceeding expected background extinction rates

Moral Obligation to Preserve Endangered Species Many species that exists today are becoming endangered to extinction. In the past era where humans did not exist, extinction occurred due to natural causes. On this present time however, extinction of species are threatened by humans’ existence. Humans are the only moral agent; in which, it has the intellectual capacity that animals and plants do not have. Thus, humans are powerful and dominate over any species. Many practices that humans do such

The Triassic-Jurassic extinction occurred about 210 million years ago, killing about 80 percent of all living species (“End-Triassic Extinction”). Most species were hit hard, but there were no major full-on extinctions. Still, cephalopods, sponges, corals, reptiles, and pollen and spore producing plants were hit hard. The dinosaurs, however, were lucky and survived the extinction intact. This allowed them to reign supreme for the next geological epoch (“End-Triassic Extinction”). During the time of

In the course of Earth’s history, there have been five major extinction events: the Ordovician-Silurian, Late Devonian, Permian-Triassic, Triassic-Jurassic, and Cretaceous-Paleogene extinction events. Now, according to Pulitzer Prize-winning author Elizabeth Kolbert, we are entering another one that is caused by a single species: ours. Human beings have decimated the rainforest, hunted animals like the great auk to extinction, pumped billions of tons of pollution into our atmosphere and oceans

scientific use. Applying this contentious process to extinct organisms – known as ‘de-extinction’ - fuels further debate. Through various experiments – the first instance of cloning, Dolly the sheep in 1997, scientists have observed that this could serve as a gateway for further scientific discoveries. Also, it has been hypothesised that an ecosystem could highly benefit from the revival of an extinct species. Nonetheless, however advantageous it appears for some scientific development, the act

in Ice Age Extinctions And The Rewilding Of America. According to Martin’s perspectives he has indicated that extinction swept the way approximately half of 200 species of large mammals, for example, anteaters and sloths in the last 50,000 years, late in Quaternary. By establishing dates from the fossils of different, the author believes species went extinct and whether the extinction was sudden or gradual. A paleontologist O.P. Hay claimed whatever was involved in forcing extinctions is a issue

entertainment such as dog fighting. These things may not seem to be globally threatening, yet the constant waste of certain species of animals and the destruction of an animal's natural habitat will lead to the endangerment and eventually the extinction of the species. Furthermore, many people are unaware that the world is currently in the midst of the largest mass extinction in history. The human population's use of domesticated and wild animals is both horrific and dangerously frivolous. For

Should Research on De-extinction and Cloning be continued? Have you ever imagined how it would feel when extinct species, like woolly mammoths and passenger pigeons, are brought back to the Earth? How would it be like to revive long dead species? Obviously, many would imagine it to be amusing and fascinating. There are numerous discussions ongoing that address the prospect as well as the impacts of de-extinction and cloning. I believe that de-extinction and cloning, though seem fascinating at first
