What is the Extinction Threat Level and why is it important?

The Extinction Threat Level
(ETL) is a measurement of risk. Only an advanced sentient species (ie humans) can attempt to calculate, monitor and improve its ever-changing ETL. Once established as a measure, every event and activity can be expressed in terms of its impact on the ETL, be it positive, neutral or negative.

As human beings we face numerous threats to our long-term existence. Our success or failure to manage and reduce the risks from these threats can be measured by the changing ETL value. Used as a common measure, ETL could engender positive, aspirational and challenging goals, providing a vision for a better and sustainable future for us all. Our individual legacies will be how we have each impacted the ETL for the human race - for better or for worse. 

Successful species strive to survive, prosper and replicate, therefore reducing ETL is instinctive to most species. Adopting ETL as a global shared measure should help promote understanding of how individual and local actions, or inactions, can have an adverse or beneficial effect on the human race as a whole.

Because the Universal Extinction Constant is a permanent feature of life, the ETL is, was, and always will be relevant. Our impact on it is something we can all be judged against, irrespective of our location in space or time. It applies to every generation and it should be incumbent on each and every one of us to try and reduce it for the common good of our species. Activities that may seem beneficial on a local basis may be shown to be detrimental to the human ETL. Therefore, measuring and reporting the ETL can then be used to help modify behaviour and show what progress is being made.

The vision is to make everyone aware of the ETL for human beings and work towards reducing it.
