Extinction

that during life on Earth there has been 5 mass extinctions. These mass extinctions are said to be a normal part  of life and might even be an important factor for life on Earth. The main mass extinctions that have been discovered are the Ordovician Mass Extinction, the Devonian, Permian, Triassic, and the Cretaceous Mass Extinction. Scientists now even believe that we are not only part of the problem but the main subjects of the sixth mass extinction caused by Homo sapiens (humans). Andrew…

The K-T or the Cretaceous-Tertiary extinction, was a mass extinction over unknown origin that took out an estimated 60-75 percent of all the species on earth 66 million years ago, most famously the dinosaurs. It was the end of the Cretaceous period and the Mesozoic Era and created the beginning of the Cenozoic Era that is still happening today. Geologically speaking this extinction happened in a very short amount of time. Although the most well known species to go extincted during this time was…

These species, along with many others have gone extinct over the course of time and now only fossils remain. However, Scientists are using biotechnology in an attempt to bring these species back from the dead. This process is known as de-extinction. De-Extinction, also known as resurrection biology, is the scientific process of resurrecting species that have died out, or gone extinct (Britannica). Scientists are using three different techniques in their attempt to resurrect these species; these…

biotechnology continues to advance, a matter that interests both genetic and conservation scientists is the de-extinction of species, or the resurrection of lost species. The idea of Jurassic Park, a 1993 American film where genetic scientists created a wildlife park with cloned dinosaurs, is no longer science fiction. It is becoming an increasingly considered possibility, and with the present-day extinction rate of species higher than ever, scientists have commenced to ponder the prospect of…

The 6th Mass Extinction? Species of animals and plants go extinct all the time due to their lack of evolutionary ‘fitness’, for example, the giant panda is on the brink of extinction because it can only eat one food, and can only copulate a couple weeks out of the year, but sometimes, It 's not their fault… a mass extinction is “the extinction of a large number of species within a relatively short period of time, as between the Cretaceous and Tertiary Periods when three-quarters of all species…

The documentary "Racing Extinction" was first released January 25, 2015. Some of the people involved in the documentary are Filmmaker Louie Psihoyos, along with activists and scientists. In "Racing Extinction" pathos, ethos and logos were used frequently. The documentary is about how most of man can is trying to take over other species need for the world to work properly. In the documentary pathos played a great part in the film. When they saw an animal with no fins that was struggling to…

E Pluribus Unum is drooping sadly out of the greenish beak. Or maybe replace the dodo with a velociraptor. Or a Western Black Rhino. All of these stories have sad endings, with the dodo and velociraptor going extinct thousands of years ago. But extinction isn’t something that happened to the dinos and the dodo birds. The Western Black Rhino went extinct just a few years ago, in 2011. Poaching, mostly, and lack of local drive to end poaching, ended the presence of this beautiful creature on earth…

Humans May Be The Cause of The Sixth Mass Extinction Where have all the animals gone? Mass extinctions are periods in time where large numbers of species go extinct. Newsela staff claims that "The most famous mass extinction came from space, but the biggest might have been because of carbon dioxide." Scientists predict that humans could be the cause of the 6th mass extinction. Humans burned off ages worth of different types of fossil fuels, because of this the climate has changed. According to…

species have evolved. Today, these changes are partly caused by human beings, rapidly causing a massive extinction—one that Elizabeth Kolbert calls the sixth extinction. Kolbert argues that due to humans getting involved in atmospheric and oceanic procedures, as well as affecting the principles of geographic distribution, we are either already in the process or at the very edge of this extinction. “We are running geological history backwards,” she stated during her lecture at Skidmore College.…

Humanity is blessed to have evolved on earth. Biodiversity and beauty can be seen almost anywhere, but it has been decreasing quite rapidly in short period of time. Reading The Sixth Extinction by Elizabeth Kolbert is a must to understand how significant humanity’s impact is on our world. The decision to destroy or to save it rests in our hands. Most of this responsibility falls on you, Director Pruitt; you have the resources and power to uphold the ethical treatment of our lands and animals.…
