There's less need to save endangered species if we can print new ones at will. We should transmit the DNA codes and instructions how to build out to the universe in all directions. If some advanced life form picks it up there could be Earth elephants and wild horses everywhere billions of years from now. Even you could be on the reincarnation list.
Just think of the fortune we could make printing out new husbands/wives after a divorce. Or even before:) Just add up the "qualifications" and head for the magic printer.
