The number of the beast
You don’t have to have experienced the Great Migration up close to know that the annual manoeuvres of wild grazer herds is a thing of both great beauty and complete wanton destruction. To understand the former and limit the latter, Australian scientists are embarking on the “world’s largest satellite herd-tracking programme“. They plan to tag about a thousand buffalo with GPS devices, and monitor their activity from space. We expect great dataviz tracking these moo-vements soon.
