De Romeinen hadden een grote houthonger en dus gingen onze bomen massaal voor de bijl Onze contreien maakten een eerste grote ontbossing mee onder de Romeinen, die brandstof en bouwmaterialen nodig hadden. Bij de val van hun rijk hield de kaalslag op, concludeert onderzoek op jaarringen van archeologische vondsten. “Er valt iets uit te leren over hoe we onze bossen duurzaam kunnen beheren.”
