Breakdown
  • Canada's wildfires emit enough carbon to triple national emissions annually 4s
  • Ancient buried cedar log found intact, still storing carbon after 3,700 years 38s
  • Company buries fire-killed trees to generate carbon credits and fund reforestation 1m 11s
  • Carbon bunkers prevent wood decay by excluding oxygen, locking away carbon 1m 43s
  • Ecologists warn large-scale burial could disrupt natural nutrient cycles 2m 10s
