Aborigines came to Australia and burnt out most of the trees and bushes. The megafauna starved whilst eucalypts, herbs, grasses and mesofauna flourished. The ancient culture survived an ice age, global warming and hugely rising seas, forging economies in woodlands and deserts. Europeans doused the firestick, woodlands turned to scrub, mesofauna perished, megafires and tree-eaters irrupted. Foresters rekindled the firestick and greens stole it. Megafires and declines are back with a vengeance whilst ecologists dream-up reasons not to burn. Ecological history shows that we must apply the firestick frequently, willingly and skillfully to restore a healthy, safe environment and economy.
