“That’s a new paradigm in conservation,” he says. Ryder’s self-professed “extremely ambitious and challenging goal” is to take a functionally extinct species and use advanced reproductive and genetic technologies to produce northern white rhinos that can reproduce, restore their gene pool and return them to the habitat they once occupied. “We not only have banked living cells from 12 northern white rhinos since 1979, but we’ve determined that that number of individuals has sufficient gene pool to actually produce a viable and sustainable population.” The facility, containing the biggest and most diverse catalogue of its kind, stands as an incredible resource for assisted reproduction. A Frozen Zoo run by the organisation contains living cells and embryos from 1,000 species, one of which, a bird called the po’ouli, became extinct in 2004. “The alternative is to say goodbye,” says Dr Oliver Ryder, the director of conservation genetics at the San Diego Zoo Wildlife Alliance. Parallel efforts to implant reproductive cells created from stems into females are also under way. It could take decades to have a reasonable number of babies.” Then, attention will shift to letting them loose sustainably in the wild, the “ultimate goal”.
WESTERN BLACK RHINOCEROS ALREADY GONE EXTINCT HOW TO
His associates in Italy have been able to make embryos and now they are fine-tuning how to impregnate the surrogates. Within four years, a northern white rhino could be born from the embryo method, says Stejskal. So Hildebrandt and colleagues, coordinated by Stejskal, stepped up efforts to collect eggs and sperm.Īrt reflecting life: a digital northern white rhino at the Lost Rhino exhibition. Previous efforts to insert hormonal implants or artificially inseminate females failed, as did transporting the last two males and females to Kenya where it was hoped they would be more likely to breed. “This is completely cutting edge in terms of endangered species,” says Jan Stejskal, the international projects director at the Dvůr KrálovFé zoo in the Czech Republic, where the last northern whites were born. Eggs have also been collected from the last reproductive female rhino thanks to a team led by Thomas Hildebrandt, head of reproduction management at the Leibniz Institute for Zoo and Wildlife Research. It is stored in a cryogenic tank in liquid nitrogen at a laboratory on the outskirts of Berlin. Around 300ml of semen from Sudan and four other males, who he outlived, was collected over 15 years thanks to a variety of methods to arouse the animals, including one scientist jumping on the last male’s back. Scientists who collected semen and eggs from the last living members of the rhino species hope to be able to implant embryos into a cousin of the northern white rhino as part of nascent repopulation efforts which, if successful, would be unprecedented.

If entrepreneurs can provide a commendable solution to this issue with products that will satisfy the same customer needs, the market can become more sustainable and ethical.
( ) Those are things that can be substituted with a multitude of other products that contain similar “ingredients”! Entrepreneurs can see this as a “painkiller” start up idea and come up with ways to replace the use of ivory in the aforementioned products this is an issue that is bugging the world right now, and horns will be missing in the future if the extinction of rhinos keep increasing. For example, ivory are mainly used for jewelry, medicine, ointment, or simply decoration.
As business people who believe in creating shared value, there are things that we can do to help animals who are poached for their ivory. However, the root cause is due to poaching. It has been said that if more effort were put in for conservation, perhaps the fate of these extinct/near extinction species could be very different. A dead Western Black Rhino with its horn removed.
