A fire in 2020 seems to have destroyed 1/10 of the world's giant redwood trees.

The fire's intensity was partly due to human fire-suppression activity. We could prevent wildfires from being intense enough to damage those trees by doing a lot more controlled burns, but that is easier said than done. It is hard to keep a controlled burn under control in times of deep drought, and even harder when flammable debris has accumulated.

It would make sense to grow more giant redwood groves in widely separated places.
