Why should we protect polar bears reading Cambridge?
Why we need to protect polar bears. Polar bears are being increasingly threatened by the effects of climate change , but their disappearance could have far-reaching consequences. They are uniquely adapted to the extreme conditions of the Arctic Circle, where temperatures can reach -40°C.
Could cloning extinct animals?
To successfully clone an extinct animal, scientists need to find animal DNA that is almost entirely intact . Some species have substantial potential as candidates because of the availability of what is called ancient DNA, or genetic material from fossils or artifacts.
What would be some advantages of bringing back extinct species?
The same reasons will apply to species brought back from extinction: to preserve biodiversity, to restore diminished ecosystems , to advance the science of preventing extinctions, and to undo harm that humans have caused in the past. Furthermore, the prospect of de-extinction is profound news.
How can we bring extinct animals back to life?
Cloning is a commonly suggested method for the potential restoration of an extinct species. It can be done by extracting the nucleus from a preserved cell from the extinct species and swapping it into an egg, without a nucleus, of that species’ nearest living relative.
Why de-extinction is a good idea?
Focusing on de-extinction could compromise biodiversity by diverting resources from preserving ecosystems and preventing newer extinctions. It could also reduce the moral weight of extinction and support for endangered species, giving the false impression that reviving an extinct animal or plant is trivial.
Why is de-extinction important?
De-extinction provides an opportunity for humans to rectify past harms inflicted on other species , as well as to expand species diversity. But many extinct species were driven out of existence as a result of habitat loss, and others lived in habitats that have since been altered dramatically.

Can we bring back Neanderthals?
The Neanderthal, also known as homo neanderthalensis, could be up for making a come-back . The Neanderthal genome was sequenced in 2010. Meanwhile, new gene-editing tools have been developed and technical barriers to ‘de-extinction’ are being overcome. So, technically, yes, we could attempt the cloning of a Neanderthal.
Should extinct species be brought back into existence essay?
