“The Department of Defense is now looking at ways to clean up after itself, putting out the call for the development of biodegradable ammunition loaded with seeds that sprout plants after being discharged.”
See US military seeks biodegradable bullets that sprout plantsIn the last desperate days of WWII, my father encountered wooden bullets fired by German forces in his direction. Of course such bullets lacked range or accuracy but they would be dangerous at close range. OTOH, they convinced “our guys” that we were winning and that the end was near. It was. A few months later he was married and at home causing the “baby boom”…
Well, USA doesn’t intend wooden bullets to make a comeback in use against hostile forces, but just to make firing ranges less of a bio-hazard. That’s good. I shoot at a range where most bullets end up in a berm filled with lead, copper, zinc, steel and other stuff that while natural is not normally found in high concentrations near the surface of Earth. Living things find these metals toxic. Keeping them concentrated on ranges at least minimizes the risk to the rest of the environment but it’s just delaying the problem as rain can move some of the material into aquifers or wind and erosion can spread it over the surface. Heaven only knows what various critters will do with the stuff.
It’s a cute idea to have expended rounds deposit seeds but it could be beneficial not in berms but large areas where war-games and such are carried out. There, tracked vehicles may erode flora on the surface and explosions can kill grass, weeds, trees and shrubs so rejuvenation is a good idea. Too bad we can’t make rounds that would convert murdering bastards into kind, loving people.
