A beaver family in Canada has built a dam extending 850m – which is more than twice as long as the Hoover Dam. It is so big that it can be seen from outer space. But that is not the only reason NASA is interested in this architecturally minded species. Increasing diversity and resilience, not to mention creating wetlands, are just some of the impacts beavers can have on their surroundings. What does this mean for the wider environment? And how can we humans learn from it?
