Biological Eradication

This quarrel between these … species has become tiresome. We synthesized a potent acid and aerosolized it within the planet's atmosphere. As the caustic agent spread, the wind creatures dissolved into dust and the fungus shriveled and blackened. We were able to exploit existing compounds within the planet's atmosphere to cascade this effect across the entire world. After confirming that the planet had been fully euthanized, we picked it clean of all useful material.
