The article talks about forms of preservation to save animals.

Including themes such as Dolly and Noah “the cloned animals”

We’ve all had heard and used phrases like “hungry as a bear” or “smart as a fox”

These phrases grew out of people’s long association and familiarity with animals .But try to imagine a world where these were just abstract phrases because there were no more foxes or bears on earth .Many conservationists feel that if radical steps are not taken to preserve animal species and their habitats ,that world could soon become reality .

Some scientists are experimenting with a controversial way to preserve endangered species: cloning .In 1997, a sheep named Dolly became the world’s first cloned mammal .In 2000 biologists cloned a gaur an endangered species of Asian ox .To do this they first collected skin cells from a gaur that had died .Then they retrieved eggs from normal cows which had been killed for meat. With a needle, they removed the nucleus of each egg and injected a gaur cell in its place. The eggs fused with the gaur cells and began to grow and divide .These growing balls of cells were then implanted into mother cows. Only one of 44 implants survived and the result was Noah, a cloned gaur.

Naturally, there are strong arguments both in favor of and against cloning .The choices are not easy –Do we have the right to genetically engineer the future of certain species?

Trough cloning or other radical scientific procedures?

On the other hand do we have the right to stand by as more and more species become extinct? These are some of the difficult choices facing the generations of the 21st century.
