NOT SUBBED We’re at the peak of the ice age. Ice sheets that are kilometres thick are sitting over what will become Russia, Canada and Europe. People are living on glaciers on the highest mountain ranges in Tasmania and the Snowy Mountains. Huge parts of inland Australia have been turned into cold and harsh desert. Trees are gone from higher altitudes, there’s little food for grazing animals and wetlands have dried up even in tropical areas. Sea levels have dropped, exposing two million square kilometres of coastline as dry land. With large areas of this continent now completely inhospitable, people are forced to make journeys to areas that offer refuge, condensing into places known for reliable water. There’s a crash in the population as the harsh conditions take their toll.
