NOT SUBBED People have spread right out and are now flourishing in every corner of the continent, in all kinds of habitats. But just as the population is growing, a huge new challenge is coming. They’re about to be hit with an ice age. At this point only 60 per cent of the continent is desert but that’ll soon dramatically spread. Temperatures are beginning to cool. Ice sheets are forming and ice caps are expanding. It means the ocean’s water is being sucked out and stored as ice on land around the world, causing sea levels to drop rapidly. This is the beginning of an extreme drought that’ll put the survival skills of the people here to the ultimate test for the next 10,000 years.
