Back from the brink: How 'frozen zoos' could save dying species
CNN
San Diego's Frozen Zoo pioneered freezing animal cells with the aim of aiding conservation. Now, groups like The Frozen Ark and Nature's Safe are among a growing number of cryobanks working to preserve biodiversity.
"Famously, there was a poster that hung above the Frozen Zoo with a quote that said, 'You must collect things for reasons you don't yet understand,'" says Oliver Ryder, a geneticist at San Diego Zoo and an early collaborator with Benirschke. "We felt that we were stewards of this growing collection that was going to have value to the future in ways we weren't able to appreciate then."
Benirschke passed away in 2018, but his efforts are very much alive. Today, the Frozen Zoo is the world's largest animal cryobank, with samples from over 10,500 individual animals from 1,220 species.
