De-extinction is a process that has been experimented with for many years, but has never been completely successful. The ethics and consequences of this idea have been questioned but, de-extinction has the potential to be truly helpful to humans and the environment, and many of the scenarios that people think could happen, are actually impossible. To actually revive a species, there are certain conditions that must be met, and the terrible situations that people think could happen, are unable to actually occur because of the lack of . Bringing species back that are beneficial to the environment could preserve biodiversity, restore diminished ecosystems, advance the science of preventing extinctions, and undo the harm that people have caused in the past. The true potential of the revival of species cannot be realized because people overdramatize the effects and possible outcomes. Once we realize and understand how beneficial the process of de-extinction can be we can better improve our world, our lives, and our ecosystems.
The process of reviving an extinct species is not overly complicated, but it does require a few elements that may be hard to obtain from a species. In order to actually to be eligible for revival a species must have only gone extinct in the last 800,000 years (ngm.nationalgeographic.com). If a species went extinct before that, the environment that it lived in is gone and throwing the organism into this time period’s environment could have disastrous consequences. Enough DNA to sequence the organism must also be present, this assures that we know exactly what makes up the organism and allows us to have the complete “instructions” for the organism before the process starts. Also, an organism must have a close e...

...cies. This whole idea can give us a chance we’ve never had before. We can undo our mistakes from the past, we can bring back amazing species that once roamed the earth. Can you imagine a wooly mammoth, or tasmanian tigers once again able to walk next to man? With this process all of that is possible as long as we keep trying to restore what has been lost.

Humans have driven many animals extinct, but should we bring them back is the question. Geneticists, biologists, conservationists and ethicists gathered to discuss the controversies. Some people say in doing this we are playing God, while others say we did by killing them. Other scientist say that it may be beneficial because it will add biodiversity, and medicinal properties back to the ecosystem. It is only possible to bring species back from around 10 thousand years ago. Recently scientists have vastly improved the cloning process. We can now coax adult animal cells into any type of cell, including eggs and sperm, then manipulating them into full-fledged embryos, which has led to the ideas and developments of reviving many other species including mammoths, frogs and

The re-wilding of North America is basically a conservation strategy (Donlan 2005), aimed at restoring the Pleistocene era (Donlan 2005, Rubenstein et al. 2006). This could be achieved by reintroducing African and Asian megafauna, these species are phylogenetically known to be direct descendents of the extinct Pleistocene species or animals of similar taxa (Donlan 2005, Rubenstein et al. 2006). Re-populating North America is essential for both ecological and evolutionary potential (Donlan 2005) and also economic gain (Donlan 2005, Rubenstein et al. 2006). In this paper I will be discussing the main arguments presented by two papers regarding the Pleistocene North America re-wilding. The first paper is written by Donlan (2005), it is a commentary paper in which he proposes the plan of re-wilding North America based on his opinions. The second paper is by Rubenstein et al. (2006), it is a research paper where he outlines some facts contrary to Donlan (2005)’s paper, unlike Donlan (2005)‘s paper his arguments were supported by variety of recent Scientific published papers which are relevant to the topic discussed.

Today, we as a society world wide have a new issue to deal with. Science has discovered the means in which to clone animals, opening a whole new discussion. Many people are inclined to say why would science even wish to peruse this method of research. Lewis Thomas says in his essay "The Hazards of Science"

Long-term survival of a species depends on its ability to adapt to changing environmental conditions (Murphy, 1994). Genetic diversity within a species, which has taken 3.5 billion years to evolve, makes adaptations to these changing environments possible. Unfortunately, the rate of extinction of genetically diverse organisms is rapidly increasing, thus reducing this needed biodiversity, largely due to the human impacts of development and expansion. What was an average of one extinction per year before is now one extinction per hour and extinct species numbers are expected to reach approximately one million by the year 2000 (WWW site, Bio 65). As a result governmental and societal action must be taken immediately!
Imagine the howl of the Thylacine(Tasmanian Tiger), it’s fast footsteps scurrying across the plains of Australia, following the Thylacine is a baby Thylacine, racing across plains of Australia for the first time. The fast flowing blood zooming through the Thylacine’s veins once again. Restoring the homeostasis back into its habitat. What if we could bring back the extinct? What if we could restore what we destroyed once before? Bringing the extinct back can change everything. The way we study science, the way we look at the past, the way we look at the future. Resurrecting the extinct can change so much in such an enormous way. Never again will we worry about extinction, never again will we fuss about dying. We can change the future, one small

Various plant and animal species depend on each other for what each offers and these diverse species ensures natural sustainability for all life forms. A healthy and solid biodiversity can recover itself from a variety of disasters. It is estimated that the current species extinction rate is between 1,000 and 10,000 times higher than it would naturally be. Therefore, there is an urgent need, not only to manage and conserve the biotic wealth, but also restore the degraded ecosystems. c) Captivity breeding species can again be reintroduced into the wild.
