Extinction

Mammoth was hunted down by humans. “Some experts hold that mammoths were hunted to extinction, beginning some 10,000 years ago, by the species that was to become the planet's dominant predator, humans” (AFP, 2010). If Woolly Mammoths were hunted down to extinction, that means they must be really dangerous animals that humans didn’t want them alive anymore. They can help us protect species that are close to extinction, that is what scientists and researchers would say, but from what we know now,…

Natural and Unnatural Causes of Wildlife Endangerment and Extinction Animal extinction is a huge epidemic that is happening faster than we ever expected. Endangered species are dying off left and right due to natural and unnatural causes. Things like poaching and global warming are constantly effecting our environment and changing the way species are living every day. All humans have a responsibility to take care of our environment, which, in turn, will help protect our species and others as…

River Otter, the Western Black Rhinoceros, and the Alaotra Grebe; what does each of these species have in common? They are all extinct. Extinction is not necessarily a bad thing like how most people know it to be. It is perfectly normal for species to naturally die off, but not at the rate that it is going now. There are natural abnormalities in the extinction rate, like with the dinosaurs and their meteor, but not this time. These species are just a fraction of the many species that are…

A Swedish scientist claims in a brand new theory that mankind has surpassed four of the nine limits for keeping the planet while another professor told RT Earth could be finding an imminent human-made extinction of numerous species. Those nine contain carbon dioxide concentrations, preserving at 90 percent, using phosphorous and nitrogen, keeping 75 percent of first woods, aerosol emissions, stratospheric ozone depletion, ocean acidification, fresh water use as well as the dumping of pollutants…

are everywhere. Most cities have zoos, where families, tourists etc can go and see a variety of animals. People love to go to the zoo to see the animals, but what about the animals? Does zoo life affect the health and well-being of the animals? Is extinction natural selection? Are animals bred in captivity able to be released into the wild and if not, what's the point in breeding them? These are the questions that need to be answered for the animals and their well-being. Zoos do keep the…

all examples of why we need Biodiversity. If I were to describe each and every dinosaur with one word it would be extinct. Why because they are all extinct. {Extinction is what happens when a taxon of organisms vanishes from the face of the Earth, meaning there is no more of that said species left, neither in the wild nor in captivity. Extinction occurs mainly due to the rapid changing of the environment. For example many species that lived and thrived during the Ice Age died off because of the…

Introduction: We are running an experiment using pigeons that will teach us about resurgence after extinction. Previous studies, such as Leitenberg et. al (Leitenberg et. al, 1970), have shown that it is possible for a behaviour that has been previously extinguished to have a sudden resurgence and become prevalent again. Podlesnik et. al, (Podlesnik et. al, 2006) attempted to re-create this experiment, and found the same results, the rats relapsed and returned to their previously extinct…

currently losing approximately 1,000 to 10,000 times the average amount in accordance to the background extinction rate (Extinction). With this in mind, there are currently less than 60 Amur Leopards in the wild and 200 in captivity with fundings furnished by the World Wildlife Fund (WWF) (Endangered Species Conservation). Furthermore, in order for the Amur Leopard to be considered “not at risk” of extinction, there has to be a minimal amount of 100 species in existence. However, in 2007, the…

vulnerable to habitat degradation. Due to the threats, species in this hotspot are some of the most endangered in the world and species extinction rates are high, especially for birds and mammals (McGinley, 2011). Humans use animals for food, medicine, building materials, and ornamentation. They have converted land for agriculture and hunted many birds and reptiles to extinction. The fossil record for the hotspot reveals that as many as 2,000 bird species have disappeared since humans colonized…

Panda bears are a beautiful species but it won't be a species for long if we don't help them, They are in extreme danger of extinction. Panda bears are in the edge of extinction because their habitats are destroyed by humans, some are killed by poachers, and they have a hard time surviving in reproduction. To illustrate, Why are Panda bears in extinction why can't they be like dogs that you can see them everywhere.Pandas habitats are mostly destroyed by humans, when they destroy their…
