Scientists Propose Lunar Biorepository As 'Backup' For Life On Earth

An anonymous reader quotes a report from The Guardian: With thousands of species at risk of extinction, scientists have devised a radical plan: a vault filled with preserved samples of our planet's most important and at-risk creatures located on the moon. An international team of experts says threats from climate change and habitat loss have outpaced our ability to protect species in their natural habitats, necessitating urgent action. A biorepository of preserved cells, and the crucial DNA within them, could be used to enhance genetic diversity in small populations of critically endangered species, or to clone and create new individuals in the worst-case scenario of extinction.

The proposed lunar biorepository, as described in the journal BioScience, would be beyond the reach of climate breakdown, geopolitical events or other Earth-based disasters. The moon's naturally frigid environment means samples would remain frozen year-round without the need for human involvement or an energy source. By taking advantage of deep craters near the polar regions that are never exposed to sunlight, the moon is one of few places that can provide the ultra-low temperature of -196C necessary to preserve the samples in a way suitable for future cloning. Besides those facing the imminent risk of extinction, the proposed repository would prioritize species with important functions in their environment and food webs. Through careful selection, those housed could be used to re-establish an extinct population on Earth or even to terraform another planet. Dr Mary Hagedorn of the Smithsonian's national zoo and conservation biology institute and the proposal's lead author believes the biorepository proposal will come to fruition, although perhaps not in our lifetime: 'We know how to do this and can do this and will do this, but it may take decades to finally achieve,' she said.

The report says the next steps 'will be to develop packaging for the cryopreserved samples that can withstand the conditions of space, and to work out the logistics of transporting samples to the moon.'
