Global catastrophic risks is a domain of research, philosophy, and governing efforts directed at understanding and preventing humanity from unrecoverable events. A number of organizations and individuals are explicitly or implicitly focused on GCR prevention. 

GCRs are diverse. Some mitigation efforts are straightforward but costly, namely, Asteroid impact avoidance. Some require global coordination, such as Biological risks and pandemic prevention. Some stem from international tensions, namely risks of nuclear war. And some arise from our efforts to address other urgent global issues, e.g. risks associated with solar radiation management in response to climate change. 

At the core of risk management, there is a psychological conundrum.  Managing risks is not fun, it does not give you a competitive edge and motivation to engage with it is purely negative. This means that we tend to avoid thinking about risks until the point that catastrophic events seem almost unavoidable. Moreover, risks are boring and hard to work with. Worst of all - If you work on risk prevention - when you do your work well - nothing happens.  Risk mitigation is essentially a hygiene procedure, akin to brushing teeth or, more appropriately, cancer checks. It is something that, when done properly, prevents much bigger and possibly lethal problems.  

So, humanity is not yet there, we don't brush our teeth and don't do our annual check-ups. We do have systems for checks and balances in place for many other things so we'll likely arrive there also for GCRs. But that requires developing a common vision for humanity. If all you care is to make it through the day, there is not much motivation to do cancer checks.
