We could grow jet fuel on gum trees — if there’s anywhere left to plant them

Scientists are one step closer to using Australia’s iconic gum trees to develop low-carbon renewable jet and missile fuel. The only problem is, the habitat of more than 90% of eucalypt species is set to decline in the near future due to climate change.
