There are many other species of wild life animals such as the Texas Red Wolf, which are endangered. Scientist can clone more of these animals and reintroduce them back into the wild. Animals are not only the ones who are endangered. There are several plant species, which are also endangered. Human intervention in the wild has caused many endangered species.
Cloning can be a way for humans to make up for their intrusion with nature.
Even with all the possible benefits cloning would bring us, there will be those who go past the natural boundary of life. Therefore cloning will need strict regulation. The best way to do that is to form a worldwide organization with delegates from each country, each experts in biology and having vast knowledge of cloning, despite the extreme difficulties accomplishing this task. However this is the only logical solution. We could lose too much if we ban cloning.
