Despite increasing international efforts to protect the natural habitats of endangered species of animals, the rate at which these species are becoming extinct continues to rise. It is clear that these efforts are wasted.

Summarize Argument
International efforts to protect the natural habitats of endangered species are wasted. This is because the rate of extinction for endangered species continues to grow.

Notable Assumptions
The author assumes that if the rate of extinction for endangered species rises, then international efforts to protect their habitats are entirely wasted. Furthermore, the author assumes that the rate of extinction for these animals would not be significantly higher without the international efforts to protect their natural habitats.

A
Scientists are better able to preserve the habitats of endangered species now than ever before.
This does not affect the argument. While scientists may be better able to protect endangered animals’ natural habitats, the rate of extinction for these animals is nevertheless increasing.
B
Species that would have become extinct have been saved due to the establishment of animal refuges.
This weakens the argument. It exploits the author’s assumption that if the rate of extinction for endangered species rises, all efforts are wasted. (B) says the efforts are not being wasted, as species are being saved from extinction.
C
Scientists estimate that at least 2000 species become extinct every year.
This does not affect the argument. While the increase in the rate at which endangered species are going extinct is a key part of the argument, the actual number of species that go extinct in a given year is not relevant.
D
Many countries do not recognize the increased economic benefit of tourism associated with preserved natural habitats.
This does not affect the argument. Countries failing to recognize other benefits of efforts to protect natural habitats does not weaken the conclusion that the protection efforts are wasted because the rate of extinction of endangered species continues to rise.
E
Programs have been proposed that will transfer endangered species out of habitats that are in danger of being destroyed.
This does not affect the argument. Proposed programs (i.e., programs that do not currently exist) are outside the scope of the argument.
