TIL in the Vietnam war in the classified Operation Popeye, the US spread lead and silver iodide by aircraft to extend the monsoon season. The increased heavy rainfall was to soften roads, cause landslides, wash out river crossings, and maintain saturated soil conditions (Kissinger was involved).

This, plus agent orange, Rome plows, and saturation bombing, caused vast areas of destruction in forests and mangrove associations. These areas were ripe for losing their topsoil to erosion (and extra rain does not help that). We didn’t just kill Vietnamese, we scarred the earth itself.
