LUND, Sweden (IDN-INPS) – “Suppose aliens existed, and that some had been watching our planet for its entire forty-five million centuries, what would they have seen? Over most of that vast time-span, Earth’s appearance altered very gradually. Continents drifted; ice-cover waxed and waned; successive species emerged, evolved and became extinct.
But just in a tiny sliver of Earth’s history – the last hundred centuries – the patterns of vegetation altered much faster than before. This signaled the start of agriculture – and then urbanization.” We are at the very end of that “sliver”.
