Disarm – or we will reforest you!
Back in 1997, Moshe Alamaro “designed conical canisters, of a starchy biodegradable material, which each contain a seedling packed in soil and nutrients. The canisters are dropped from a low-flying plane, so that they hit the ground at 200 m.p.h., and imbed themselves in the soil. Then the canisters decompose and the young trees take root. A large aircraft could drop as many as 100,000 saplings in a single flight: Alamaro’s system could plant as many as a million trees in one day.” Whole forests, fired from F-16s.
Or, branching off from an earlier comment on the agri-militaristic possibilities of garden wars, you’d get landscape design by Cruise missile: launched from a ship in the Indian Ocean, soon there are rich deciduous forests in the hills of Afghanistan.
