Extinct Animals

The number of wild animals on Earth has halved in the past 40 years . Creatures across the land, rivers, and the seas are destroyed as humans killed them for food in unsuitable numbers, while polluting or destroying their habitats.

The last mechanism of extinction is habitat fragmentation. This is the process by which habitat loss results in the division of large, continuous habitats into smaller, more isolated remnants. A perfect example of this is the Sumatran Rhino that was such a big population that was considered a pest until their habitat was fragmented. This decreased their population and when put in captive breeding they decreased even

The poop of the Galapagos Penguin fertilizes the land allowing for the healthy growth of plants which are consumed by other animals that live on the islands. If the Galapagos Penguin became extinct, it could possibly cause the extermination of local plants such as the “Ulva” leading to the extinction of the animals which rely on them. These include the “Parrot Fish”, Sally Lightfoot Crabs, “Five-Spotted Anthia” as well as many more species of land and sea

According to Clifford et al. , The total population for the species in 1994 was approximately 6,000 adults but current population size is less than half that, and island foxes have declined by over 90% on four of six islands (p. 442). By 1995 ecological monitoring on San Miguel and Santa Cruz Islands in the national park had detected rapid and alarming declines in the populations of island foxes there Faced with the imminent extinction of three island fox subspecies, NPS convened ad hoc recovery team in 1999 to assess the status on the northern Channel Islands and to recommend emergency recovery actions. The team, comprising experts in canid conservation, endangered species management, and raptor research and management, concluded that island foxes were rapidly declining toward extinction on the northern Channel Islands. National Park began emergency recovery actions in 1999, with the objectives being to remove the primary mortality factor now affecting island foxes, and to recover island fox populations to viable levels through captive breeding.

Humans played a major role in the extinction of large mammals because hunters possibly killed them off. They were also slaughtered with knives and stampeded over cliffs at that time at which their species became less and less. to extinction in a period already providing great stress due to the receding ice sheets as the last glacial maximum came to an end. Later, this would mean a lack of analogues

Extinction: Most species become extinct because they can’t cope with the environmental change, and also because of introduced species that turned into competitors for

Megafaunal extinction: The extinction of large animal species such as mammoths and several species of horse and camels. No one knows what caused their extinction, whether it was from the excessive hunting or the Ice Age becoming a drier climate.

The ecological conditions might have changed quickly and the species was not able to adapt to those conditions, which eventually lead the species to go extinct.

One cause why some animals are going extinct is because of hunting. The animal(s) kills other animals and people then kill that animal(s). According to U.S Department of Agriculture it mentions that, “In 2010 wolves killed 570 adult cows and 1,990 calves (baby cows) in Idaho. Montana had 440 adult cows die and 852 calves. Finally, then Wyoming with 74 adult cows and 511 calved dead from wolves.” There are more wolves in Idaho then Wyoming and Montana which also means that more

There are several hypotheses that are used to explain the causes of mass extinctions. Climate change, the warming or cooling of global environments over a short period of time, can lead to other occurrences. Shifts in climate can cause extinction by

One way the Little Swan Island Hutia went extinct is the introduction of cats. They were eventually released onto the island prior to 1960. Another way they went extinct is when a severe hurricane (hurricane Janet) hit in 1955 which also could

In a summary, Kolbert explains the extinctions of a variety of different major animal species that became extinct. She also explains that if trends in the environment continue that the biggest extinction in history will occur soon. If global warming, deforestation, and glaciers continue to melt she says that more and more species will continue to become extinct. She explains how humans need to be more conservative and careful with what they’re doing to prevent extinction.

Throughout evolution, many species have come and gone. What causes a species to become extinct and what can the human race due to prevent it? Many species’ population decline has been linked to human causation. An endangered species is defined as “plant and animal species that are at risk for extinction” (Funk). Endangered species can be placed into two more specific categorizes. Threatened species are species at risk for endangerment, while endangered species are at risk for extinction. Despite the fact that many people believe extinction is a major issue, the Funk and Wagnall’s New World Encyclopedia states that, “extinction is actually a normal process in the course of evolution” (Funk). Over time, numerous species have become extinct, usually as a result of climate changes, inability to adapt, or predation. Another major cause of endangerment is the human population. Pollution, global warming, and hunting is all causing a decline in the population of numerous species. While the encyclopedia is entirely fact based, many authors have worked to sensitize people to threatened species. For example, renowned author Sharon Begley, has written numerous articles to inform people of the importance of many species that are often overlooked.

An example of an extinct species is a emu, an emu was an animal that fought a war also known as “Great Emu War”And the emus won the war!The emus were not afraid of humans at all but that's not the reason why the war started! The Great Emu War started because emus would go on farmers fields and eat the crops.So the farmers couldn’t take it any longer so they called the ex-soldiers,and then they asked the minister of defence and he started a war between emus and humans

There have been five well known extinctions on this earth. The one most well known is the mass extinction that ended the dinosaurs. Mass extinction is often described as the elimination of a large number of species in a short period of time. Despite what many think, the elimination of species is almost commonplace at this point. The Earth is currently in the middle of a sixth mass extinction, and it’s been caused by the human race.
