Greenland Released 27 Musk Oxen — Now 20,000 Are Holding the Arctic Together

In 1962, 27 animals were released into a Greenland valley with no plan, no monitoring, and no expectation of what would follow. What happened over the next six decades quietly changed our understanding of how the Arctic works — and what might be holding it together. This is not a story about conservation. It's a story about a mechanism nobody knew existed until a researcher built a fence in 2011 and measured what was on the other side.
