While A global collapse could be described as a sudden event, more than likely it will be a slow series of preventable events that leads to a rapid decline in society’s ability to function. It can be caused by many things such as an economic crisis, natural disasters, or social instability.
The term “global collapse” can be used interchangeably with the term “societal collapse” which is defined as a drastic change in the way people live their lives. This can happen due to any number of reasons including natural disasters or economic crises.
We are not currently in a global collapse but we might be approaching one if we continue on this trajectory.
