“De-extinction Probably isn’t Worth it”. This is the name of an article by Sarah Zielinski. I completely understand what she is talking about in her text‚ and I agree with her. De-extinction isn’t worth it mainly because it would take attention from other research‚ harm living creatures‚ and most of their habitats and food are gone. If we brought back extinct animals‚ it would take a lot of funds and research‚ causing us to forget about other research projects. In Mrs. Zielinski’s article she told

As the human world continues to work towards globalization‚ or a more interconnected world‚ the livelihood and future of nearly all animal species is threatened. The book‚ “A Sixth Extinction”‚ written by Elizabeth Kolbert‚ provides insight into the deeply rooted impact humans have caused on the natural world in a way that no species has done before. The largest and most devastating impact on animals that results from human globalization

In the book The Sixth Extinction the author Elizabeth Kolbert writes about the major problem our planet is facing. Humans are causing a new mass extinction. There have been five major mass extinctions in the past. Unlike the others this extinction is caused by humans. It is occurring at incredibly fast rate because of the climate change. She also mentions how increased hunting in the bird the great auk caused them to eventually die off. This book is about the negative human impact on this planet

Destruction of the Bison” is an Environmental History novel comprised of a variety of evidence as to why the Bison became extinct. Andrew C. Isenburgs thesis states‚ “A host of economic‚ cultural‚ and ecological factors pushed the bison toward their near extinction. That diverse assembly of factors first emerged in the middle of the eighteenth century from ongoing encounters among Indians‚ Euro-Americans and the Great Plains environment”(Isenburg‚ 1). There are three main themes and topics that are focused

Pandas are cute cuddly and one of the most beloved animals in the world. Sadly‚ there are only 1600 pandas left living in the wild. We never ask ourselves what’s the reason for their extinction‚ but we really want to save them no matter how is it going to reflect on people. The reason for their extinction is a habitat destruction‚ mostly caused by humans as the population of China increases. The animal world’s dilemma is should we save pandas or should we let them extinct? As most of you could think

Extinction of Dinosaurs Two-hundred and thirty million years ago the first dinosaur-like creature roamed the earth. Dinosaurs were a very successful and diverse group‚ dominating the terrestrial environments of the earth for 160 million years. The apparently sudden mass extinction of dinosaurs marks the boundary between the Cretaceous and Tertiary periods. Though there is not one definitive explanation to explain dinosaurs’ extinction‚ there are various theories that attempt to account for the

The mass extinction of dinosaurs is still a mystery today but their are many theories supporting how and why approximately 70% of all living species on earth suddenly became extinct including dinosaurs‚ 66 million years ago. The most common and realistic theory is the astroid impact theory when a astroid 6-15 km in diameter hit earth with the force of five billion atomic bombs. Another possible theory is climate change‚ the dinosaurs didn’t adapt fast enough to the climate when it was changing and

It is believed Earth may be in the midst of another mass extinction‚ also known as ’The Sixth Mass Extinction ’. This mass extinction is the first for 65 million years since the Cretaceous-Tertiary period. "It ’s the next annihilation of vast numbers of species. It is happening now‚ and we‚ the human race‚ are its cause ’ (Leakey‚ 1995). Every year‚ between 17‚000 and 100‚000 species vanish from our planet‚ which will result in fifty per cent of the Earth ’s species vanishing inside the next 100

consequences of the removal/extinction of an organism from the food web? The extinction or removal of an organism from a food web can affect different organisms directly or indirectly‚ depending on the trophic level the organism is and in what role they play in the food web‚ if it is carnivore‚ herbivore‚ omnivore‚ etc. Extinction has also been important for evolution in food webs. Some food webs are generated from the reaction with repeated extinctions‚ and the extinction rate is affected by food
