To complement its efforts to conserve nature in the wild, the Convention on Biological Diversity should develop a comprehensive and adequately funded global effort to preserve intact genomes and viable cells for every known species and for new species as they are discovered. Super-cold freezing is the current method of choice, from a whole rhino skin to a bacterium.
Freezing tissue costs $200–300 per species, with negligible maintenance costs. Preserving material from all the roughly 1.8 million known species would cost about $540 million. The United States spends more than $1 billion every four days on the war in Afghanistan. So less than $1 billion to preserve the DNA of all known species on Earth, with whom we share billions of years of evolutionary history, seems like good value.
The U.S. gives 40 percent of the [World Food Program's] budget. So if you cut 40 percent by 40 percent, that would come to 12 million people a year not getting access to food support.
