Elements of Earth's natural order, like spiders and our water system, are wonderful when you know more about them. But the whole system is wonderful in itself. Natural elements are balanced for a healthy ecosystem.
Beavers were a traditional, natural element of the landscape of Scotland. Then they completely disappeared due to over-hunting . .
Until this century. They're back after going extinct 400 years ago. In only 15 years, their resumed presence in the landscape made welcome and wonderful changes to Scotland's rivers. Flooding declined. Clarity improved and wildlife returned. Droughts were less destructive.
"Beavers re-built the living fabric of the river."
More: dam-building is instinctual. If the sound of running water is played in a dry environment, a beaver will pile sticks on it. Where does instinct come from? Maybe an algorithm built into the brain.
