Modern civilisation is heading for collapse within a matter of decades because of growing economic instability and pressure on the planet's resources, according to a scientific study funded by Nasa.
Using theoretical models to predict what will happen to the industrialised world over the course of the next century or so, mathematicians found that even with conservative estimates things started to go very badly, very quickly.
Referring to the past collapses of often very sophisticated civilisations - the Roman, Han and Gupta Empires for example - the study noted that the elite of society have often pushed for a "business as usual" approach to warnings of disaster until it is too late.
In the report based on his "Human And Nature Dynamical" (Handy) model, the applied mathematician Safa Motesharri wrote: "the process of rise-and-collapse is actually a recurrent cycle found throughout history".
His research, carried out with the help of a team of natural and social scientists and with funding from Nasa's Goddard Space Flight Center, has been accepted for publication in the Ecological Economics journal, the Guardian reported.
