factors that are leading to the extinction of animals is deforestation. Mass deforestation by human has cost a lot to the habitat of animals. The animals are being forced to move away from their natural habitat as it is being destroyed by human. Major source of food for animals came from forest‚ when human make the decision‚ they already made the doomsday for animals. Eventually the animals will starve and die. Global warming often caused major problem to human being‚ but we must not forgotten

Extinction and Evolution Ecology helps us understand the importance of mass extinction in evolution‚ and it also helps us understand some of the causes of extinction. Ecological niche is one of the most important concepts to understand. An animal or plant lives in a certain place is active at a particular times‚ and eats certain things; all these factors describe its ecological niche. Our environment is parted into millions of ecological niches‚ each that represents a probable home for life

of climate. In terrestrial habitats‚ tropical regions are typically rich whereas polar regionssupport fewer species. Rapid environmental changes typically cause mass extinctions. One estimate is that less than 1% of the species that have existed on Earth areextant.[1][verification needed] Since life began on Earth‚ five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoiceon (the last 540 million years) marked a rapid growth in biodiversity

In the late century‚ extinction becomes common topic in our daily discussion and debates. An average of 27‚000 species is currently extinct each year and there is a possibility of 22% of extinction in the overall species if action is not taken. Animal extinction is due to human immorality and irresponsible behavior just for their own benefits. Since the year 1600‚ a total of 83 mammals species are known to have become extinct. Wildlife population depleted the trade in live animals‚ damaged habitats

Animal extinction is happening nowadays due to the multiple factors of environmental degradation. The primary cause of environmental degradation is human disturbance. Extinctions caused by human are generally considered to be are recent phenomena. When humans convert wild areas for agriculture‚ forestry‚ urban development‚ or water projects including dams‚ hydropower‚ and irrigation‚ they reduce or eliminate its usefulness as a habitat for the other species that live there. The temperature of the

Animal Extinction - the greatest threat to mankind In the final stages of dehydration the body shrinks‚ robbing youth from the young as the skin puckers‚ eyes recede into orbits‚ and the tongue swells and cracks. Brain cells shrivel and muscles seize. The kidneys shut down. Blood volume drops‚ triggering hypovolemic shock‚ with its attendant respiratory and cardiac failures. These combined assaults disrupt the chemical and electrical pathways of the body until all systems cascade toward death.

APES Humans’ Affect on Extinction If extinction is a natural part of the world‚ why should we worry about it? Speciation results in new species filling the ecological niche of extinct species. Why should we care if we speed up this process? Biologists say there are four main reasons to care about extinctions. First‚ the world’s species are a vital part of the earth’s life support system. A second reason is that species usually contribute to economic services. The third reason is that it takes

Animal Extinction Preventing Extinction Not much is thought about extinction in today’s society. One might argue that it is a small problem‚ and completely irrelevant; but according to statistics of scientific research‚ extinction is an important issue nationwide. Extinction of a species over time is undisputable‚ and inevitable; however‚ the burden of mankind on animals and their environment has caused extinction to increase severely

Elizabeth Kolbert‚ The Sixth Extinction: An Unnatural History‚ 2014 Introduction Central to Elizabeth Kolbert’s 2014 publication is the assertion that globalization coupled with industrialization have paved the way for a new epoch‚ the Anthropocene. Dubbed The Sixth Extinction: An Unnatural History‚ the text explains “Anthropocene” as a period of “a human-dominated geological" age that will see humanity usher the world into its next mass extinction (Kolbert 108).
