Fun With Plants

Farmers can wait to apply pesticides until their crop tells them which pests are attacking which plants. Hunters can ask the forest where deer congregate to do their browsing. Maybe the grass in minefields is already broadcasting the location of the explosives its roots are avoiding.
Lots of these capabilities could be built into smart phones, perhaps with sensor attachments. Even more sophisticated work could be done with special purpose devices mounted on drones or just on the Google Street View car. It’s nice to have pictures of houses along the road, but imagine Google Plant View: a map of everything the plants know about a neighborhood: soil types and pH content, homes with toxic molds, the progress of invasive insects, herbivores, and plants.
