The Extinction Of The Earth

- 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)....   [tags: Extinction, Endangered species]

The Fourth Extinction By Elizabeth Kolbert

- On a day to day basis, most people take for granted the lives we get to live, and put too much value on the extra things such as materialistic items. Also, the majority of humans are too invested in their personal lives or with themselves that they do not look at the big picture of how what we are doing now will effect us later. As humans, the routines in our lives can bring us harm, and within time a we may become the sixth extinction.

Preventing Extinction and World Change

- Thirteen years ago, wolves were reintroduced to Yellowstone National Park. Of two potential locations considered (Snowflake Springs and Butte Rock) they were placed in the low-risk prey Butte Rock for the purpose of encouraging the wolves to spread out and create packs. Before and during the reintroduction project, Oregon State University researchers measured the rate of willow growth along 2.6 miles of the Gallatin River, which ran through Butte Rock and Snowflake Springs. During their study from 1998 to 2002, the researchers discovered that Snowflake Springs, where the elk were and no wolves lived, the willow growth dropped from 92% to nothing (“How Wolves Help Willows,” 4)....   [tags: animals, Yellowstone, Extinction, linguistics,]

(Purvis, E., & Mace, 2000) Though they represent a minority of all species, island species make up 75% of animal extinctions since the 16 000's. Because of traits inherent to islands, including isolation and small geographic range (Purvis, E., & Mace, 2000), islands are more susceptible to extinction than the continents. This results in a disproportionate ratio of island to continental extinctions....   [tags: Zoology, Conservation]

In addition, according to the Oxford Dictionary of Geology and Earth Sciences edited by Michael Allaby (2013), mass extinction is defined as the Earth has been taken place environmental catastrophe, removes many groups from environment from record and not replaced, and ecosystems collapse....   [tags: environmental catastrophe, Geology]

Theories of the Extinction of the Dinosaurs

- Theories of the Extinction of the Dinosaurs Controversy surrounds the extinction of the dinosaurs. According to one theory, dinosaurs were slowly driven to extinction by environmental changes linked to the creeping withdrawal of shallow seas from the continents at the end of the dinosaur era. Proponents of this theory propose that dinosaurs dwindled in number and variety over several million years. An opposing theory proposes that the impact of asteroid or comet caused catastrophic destruction of the environment, leading to the extinction of the dinosaurs....   [tags: Papers]

The Permian-Triassic Extinction Event and It's Effects on Life on Earth

- Introduction The Permian-Triassic extinction event is undoubtedly the largest extinction event the Earth has ever seen. While evidence shows that it occurred over a great amount of time, it was effective in causing the extinction of an incredibly large portion of life on Earth. To such an extent that it took millions of years before any large amounts of biodiversity occurred again. This is why it is also referred to as the ‘Great Dying’. This paper will will analyze the survivability of terrestrial vertebrates compared to that of terrestrial invertebrates during the Permian-Triassic Extinction Event....   [tags: biodiversity, marine life, terrestrial life]

The Cause of the Dinosaur Extinction

- The Cause of the Dinosaur Extinction The biggest mystery surrounding the dinosaur is how did they die. For over 130 million years dinosaurs ruled the earth. Then 65 million years ago, at the end of the Cretaceous period, they died out. Nobody can really say what actually eliminated the species, although everyone has their very own idea. Asteroid impact, atmospheric changes (hot to cold), catastrophic eruptions and astronomical events (supernovas etc.). Some have ventured that early mammal inhabitation slowly “pushed” the dinosaurs to extinction....   [tags: Papers]

The Permian-Triassic Extinction 250 Million Years Ago

- The Permian-Triassic Extinction is a mass extinction that occurred between the Permian and Triassic geologic time periods approximately 250 million years ago; it is the deadliest of all extinctions that have occurred on Earth. In addition, during the Permian-Triassic extinction the continents of today existed as one supercontinent known as Pangaea. This was the first time in history where continental or land mass exceeded that of the ocean. This was also before dinosaurs of the Triassic period roamed Earth, during this time animals such as the therapsids, and Synapsids such as the Pelycosaurs, insects and amphibians also occupied Earth....   [tags: Pangaea, Perish, CO2]

- The Role of Fungus in the Extinction of Dinosaurs The debate over what ultimately killed off the dinosaurs is an area of great interest to not only scientists, but everyone. The dominant thought seems to be that an asteroid struck the earth at the end of the Cretaceous period and killed off much of the fauna and flora inhabiting the earth. However, the sequence of events following that mass extinction has been fairly blurry until a recent discovery, published in a recent issue of Science, by paleontologists Vivi Vajda and Stephen McLoughlin....   [tags: Anthropology Essays Paleontology Papers]

Each different language offers a different point of view of the world and culture. He said that if different languages are lost then “we lose the meaning what is it to be human.” Then the video moves on to Australia and that this country has lost “95% of their linguistic heritage.” The video brings in Peter K....   [tags: Linguistics, Language, Spanish language, Dialect]
