Summary Introduction
To review:
The requirement of the preservation of the biodiversity for future generations.
Preserving an organism's genetic information would be good enough avoiding its natural environment.
Introduction:
The biodiversity is very important for human and wild welfare. The loss of biodiversity comewith major changes to the environment and loss of many important elements of nature.

- What are our conscious and inadvertent effects on evolution and biodiversity?arrow_forwardChanging conditions put intense pressure on organisms-some of which become extinct. For example, of the original 62 species of honeycreeper found in Hawaii only 18 remain. Scientists have the technologies that may allow bringing back organisms that have become extinct. This brings up ethical questions about the cost/benefit of resurrecting extinct species and whether it is the right thing to do. Joseph Bennett, a professor of biology at Carleton University in Ontario, wanted to determine the cost of resurrecting and maintaining an extinct species. Since the up-front cost of resurrecting an extinct species is very difficult to determine, the researchers decided instead to look at the cost of reintroducing and protecting a resurrected organism in the wild. To accomplish this, the researchers considered 70 animals from New Zealand and 29 animals from New South Wales that went extinct within the last 1,000 years. From this list, they chose 11 New Zealand species and five NSW species that…arrow_forwardGive one product that you know of which comes from a Traditional or Indigenous Knowledge.
