300million extra?

Do they plan some mass-migration (presumably from the unliveable North), or it it 6devices per person, concurrently in use? I think we should be told.

If neither, the only remaining thing is to label anything that moves and add a GPStransponder: after tagging about 300million animals, anything upwards from hedgehogs really, you can combine with GoogleMaps this real-time info to avoid hitting them --- this will improve car safety no end: similar to the Gatso-alerts-stuff, a beep whenever wildlife is dangerously close to the road.
