Simple, they did a similar event when they reintroduced tortoises to the sub-Sahara. The tortoises would burror into the ground 40 feet or so and break up the heavily packed underground and allowed the rain to store there and eventually trees started growing. Let nature do its thing and the earth re-heals itself.
Something happened on the American plains recently that hasn't happened in about a hundred years. And honestly, in a news cycle that specializes in things going wrong, this one deserves your full attention for a minute.
American bison are migrating together again.
Not in a zoo. Not in a managed conservation pen. Together. Across the land. The way they did for thousands of years before we almost wiped them off the face of the earth entirely.
And the ripple effects of that movement are bigger than most people realize — because bison aren't just an animal. They're basically a whole ecosystem walking around on four legs.
Here's what most people don't know about bison: they are what scientists call a keystone species, which is a fancy way of saying that everything around them depends on what they do. Their hooves break up compacted soil as they move, creating the exact conditions that grasses need to regenerate. Their grazing — the specific way they eat, how much they eat, where they eat — triggers a renewal cycle in plant life that no other grazing animal replicates quite the same way. Their waste spreads nutrients across enormous distances, feeding insects, which feed birds, which feed everything above them in the food chain.
When bison move, the prairie doesn't just follow them. It comes back to life because of them.
For roughly a century, that process was broken. Bison were hunted nearly to extinction — estimates say there were once somewhere between 30 and 60 million bison on the North American continent. By the late 1800s, that number had collapsed to fewer than a thousand. Fenced-in, managed in small herds, isolated from the migration corridors they evolved to travel — the animal survived, but the ecological function it served was essentially switched off.
What's happening now, with bison migrating together at a scale not seen in a hundred years, is the slow flipping of that switch back on. The grasslands they're moving through are already responding. The soil is changing. The plant communities are shifting. The birds are returning. The prairie, as one researcher put it, is beginning to breathe again.
This matters beyond the feel-good headline. Healthy grasslands are one of the most effective natural carbon sinks on the planet — meaning bison migration isn't just a wildlife story. It's a climate story. It's a soil health story. It's a story about what happens when you give nature enough space and time to do what it was doing perfectly well before we interrupted it.
Conservation efforts, Indigenous-led land stewardship, and decades of patient work by researchers and ranchers who believed this was possible — all of it is behind this moment. It didn't happen by accident. It happened because people decided that a continent without migrating bison was a lesser continent, and they did something about it.
The prairie is waking up. About time.
