on one kind of animal‚ humans. Through this anthropocentric way of thinking‚ the impact of globalization on all animals besides humans is often not recognized despite the vast importance that it holds. As the human world continues to work towards globalization‚ or a more interconnected world‚ the livelihood and future of nearly all animal species is threatened. The book‚ “A Sixth Extinction”‚ written by Elizabeth Kolbert‚ provides insight into the deeply rooted impact humans have caused on the natural

hypotheses put forward for the mass extinctions at the end of the Permian and Cretaceous (KT) Periods. A mass extinction is an event in which at least 25-75% of species in the global environment are eradicated in a short period of time. Where as a regional extinction event is when the extinction is confined to a specific zone. Five mass extinctions have occurred throughout time‚ two of the most well known of these are the Permian and Cretaceous extinction events. There are several hypotheses

number of families (Sepkoski‚ 1986) and an estimated 96% extinction at the species level (Raup‚ 1979). Oceanic life suffered the most but terrestrial life forms were also greatly affected. There was a 77% reduction in the number of tetrapod families (Maxwell and Benton‚ 1987). All major groups of oceanic organisms were affected with the crinozoans (98%)‚ anthozoans (96%)‚ brachiopods (80%) and bryozoans (79%) suffering the greatest extinction (McKinney‚ 1987). The end of

I will be showing you how Cheetahs have been negatively affected by Human activity. Throughout time Cheetahs have had many impacts on the world. It has impacted the ecosystem‚ for example Cheetahs feed all types of other animals like‚ beatles‚ vultures and other scavengers. The Cheetah leaves the remaining of the carcass

Human impact on biodiversity and ecosysytem loss Magdaléna Jilečková The English College in Prague Abstract Biodiversity and ecosystem are crucial issues that have an impact to the human well-being now and in the future. Biodiversity depends on many factors but the most influentive is the habitat loss which influences the biodiversity worldwide. Humans converts native areas into agriculture and industrial areas without realising how much impact

Should cloning of animals and humans be legal? For my immediate response‚ I think that cloning of animals and humans should be illegal. This is because there is a high that the clones will develop mutations. The way cloning works is called fusion cell cloning. This process only needs two animals. It first starts of by taking the nucleus out of an adult cell. It’s then placed into an empty egg and it’s given an electric shock‚ causing it to fuse together. Finally it forms a new cell and it’s ready

Some people may own the idea that since animal is inferior to human beings‚ human has the rights to deprive lands which the animals living in. I can not confute that human needs lands eagerly‚ however‚ we still have the responsibility to call back the endangered animals. Species evolved slowly with thousands of hundreds of centuries of development. Certain species has certain type of living. As a result‚ hardly can it be alive when we suddenly changed its living pace. Certainly we know it‚ whereas

Humans‚ animals and plants have a great relationship with each other‚ they need each other‚ and they make each other’s lives better. Without plants and animals‚ human won’t be able to survive or can not live till now because humans need plants and animals to feed themselves. On the other hand‚ plants aren’t able to grow‚ too because they need to be taken care by humans. Therefore‚ human should protect both animals and plants. But human couldn’t take good care of animals‚ most of the animals in the

Humans’ Moral Obligation to Preserve Endangered Species Many species that exists today are becoming endangered to extinction. In the past era where humans did not exist‚ extinction occurred due to natural causes. On this present time however‚ extinction of species are threatened by humans’ existence. Humans are the only moral agent; in which‚ it has the intellectual capacity that animals and plants do not have. Thus‚ humans are powerful and dominate over any species. Many practices that humans
