Pine grows faster and sequesters more carbon. But native forest is better for biodiversity in the long run. Transitioning between the two offers a win-win solution.

Once the immediate crisis in North Queensland has subsided, authorities will need to grapple with how to deal with the ‘new normal’ of extreme weather events. The big question is: are they prepared?
