This is from the CommonLit "CAN DNA EDITING SAVE ENDANGERED SPECIES?" by Kathiann Kowalski .Please explain the answer.

D. Scientist agree that using DNA editing on animals to save endangered species is ethical.

Explanation:

Gene editing is a type of technology in which DNA is modified or replaced in the genome of a living organism. This technology has made it possible for  scientists to preserve the endangered species. But its ethical consideration  has been an issue with diverse views among scientists. Many researchers and organizations have expressed reservations about germ-line editing.

Kathiann Kowalski explains genetic editing process, as well as the risks and benefits that it poses to ecosystems.
