Zoo plans to bring rare animals back from the dead

I am interested in this title. Because we will be able to keep the some kind of animals which become extinct in the world. If the science will develop more and more, we can revive the animal which have already become extinct few thousands ago.

"TAKE frozen cells from a dead animal, reprogram them to become sperm and eggs, then use these to bring endangered species back from the brink.
That's the aim of a collaboration between the San Diego zoo and The Scripps Research Institute in La Jolla, California. The team's long-term goal is to coax iPS cells into becoming sperm and eggs. They will be making iPS cells from tissue held by San Diego zoo's Frozen Zoo project - which has samples from some 8400 individuals representing more than 800 species. The sperm and eggs could be used in IVF treatments to add genetic diversity to captive breeding programmes. "You could actually breed from animals that are dead," says Loring

This is extreme science development. I suppose it is accestable to use to protect the animal species by leagal way. On the other hand, I'm afraid to use morally bad way if frozen cell is popular in the world. People will not care about environment, they will rely on frozen cells. From the past history, science contributed for the human, but sometimes used to destroy something else.
