Naturalist: For decades we have known that the tuatara, a New Zealand reptile, have been approaching extinction on the South Island. But since South Island tuatara were thought to be of the same species as North Island tuatara there was no need to protect them. But new research indicates that the South Island tuatara are a distinct species, found only in that location. Because it is now known that if the South Island tuatara are lost an entire species will thereby be lost, human beings are now obliged to prevent their extinction, even if it means killing many of their unendangered natural predators.

Which one of the following principles most helps to justify the naturalists’ argumentation?

(A) In order to maximize the number of living things on Earth, steps should be taken to preserve all local populations of animals.

(B) When an animal is in danger of dying, there is an obligation to help save its life, if doing so would not interfere with the health or well-being of other animals or people.

(C) The threat of local extinction imposes no obligation to try to prevent that extinction, whereas the threat of global extinction does impose such an obligation.

(D) Human activities that either intentionally or unintentionally threaten the survival of an animal species ought to be curtailed.

(E) Species that are found in only one circumscribed geographical region ought to be given more care and attention than are other species because they are more vulnerable to extinction.

It talks about the exact logical sense. If it causes global extinction, then it should be saved.

IMO E
Because for C..How do we define local and global extinction based on the information in the argument ? Kindly explain

According to me,in E 'other species' are the ones which are not found only in such geographic regions

E reasoning is flawed - > it says species in one geographical area should be given more care because they are more vulnerable to extinction.

If any species is found only in any one particular area doesn't necessarily mean that it is vulnerable to extinction.

"Species that are found in only one circumscribed geographical region ought to be given more care and attention than are other species because they are more vulnerable to extinction."

To broad.. not specific for the argument.

(B) When an animal is in danger of dying, there is an obligation to help save its life, if doing so would not interfere with the health or well-being of other animals or people.. does not explain why not help when the species were considered same as the north island,and why help when found unique.

(C) The threat of local extinction imposes no obligation to try to prevent that extinction, whereas the threat of global extinction does impose such an obligation..correctly aims at all the aspects of the argument.

(D) Human activities that either intentionally or unintentionally threaten the survival of an animal species ought to be curtailed.
not mentioned that they are under threat because of humans.

(E) Species that are found in only one circumscribed geographical region ought to be given more care and attention than are other species because they are more vulnerable to extinction.the reasoning is wrong because its not true that species are more vulnerable to extinction because it is in circumscribed geo reg.
