This programme relies on experts' knowledge and understanding of history in order to predict the future, helping to paint a picture of what Earth will look like in the days, weeks, months, years and millennia after humans are gone. Looking farther into the future and using analyses based on the past, we see how nature will reclaim the world we live in. Eventually glass buildings topple, stone buildings crumble, successive freezing and thawing turn streets to rubble, water rises, subways flood and sewers crack. What animals will survive? What kind of plant species will survive? Will the seas be filled with fish? Will humans ever return? Will man begin the cycle again, excavating our ruins and trying to imagine what life was like before? This programme uses feature film quality visual effects from ILM and top experts in the fields of engineering, botany, ecology, biology, geology, climatology and archaeology to answer these questions. Humans won't be around forever and now we can see in detail, for the very first time, the world that will be left behind in.....Life After People.
