Imagine if hundreds of years from now, scientists excavated the abandoned ruins of some of our largest cities, what conclusions would they come to?



It happened to the Romans, the Anasazi, and the Mayans and, inevitably, one day our own modern civilisation will also fall. In this two hour special discover how a future civilisation might be baffled as to why the population of these once-great cities would suddenly abandon their technology and architecture, and turn their homes into ghost towns. Some experts believe that there is a very real risk this could happen, and the collapse of the world as we know it is closer than we think.



Examining the parallels between cultures separated by hundreds of years, explore whether the key to preventing such a global collapse today could lie in finding renewable alternatives to our dwindling energy supplies and sustainable resources. Can we learn from the mistakes of the past before it's too late?
