Living in a planet that each year travels a distance of about 930.000.000 kilometers in the well-known Sun's orbit making a total of more than 100.000 km/h. In that sense, the planet could be compared, like it frequently was with more sense by astronauts who see the scenario from a wider perspective, with a spaceship. Furthermore, each 24 hours an entire spin around itself makes another frantic speed of more than 1500 km/h in some parts of the blue planet.
Recently in time, plate tectonics was discovered promoting a new degree of instability. The phenomenon can be studied creating lesser risks in some circumstances, although this knowledge for sure starts another view, with continents in drift and magnitudes of extremely dangerous forces.
On the other hand there's an entire Universe full of activities and energies that can travel and reach Earth. The Milky Way for sure is not static and has another complexities in terms of natural forces and perhaps this might create changes in the orbit or other unknown processes.
Climate adds more instability for life, with possible devastating scenarios caused by inherent mechanisms. This factor of instability obviously interacts with our life 24 hours per day, and supposes the most important risk in statistical terms. Besides, current societies (it's maybe better to say individuals) around the world are promoting more instability due to the clear fact about carbon dioxide and other emissions and atmospheric adversities. If the temperature raises, it's too innocent to think no consequence is going to occur in a planet that was acquiring stability in a greatly unstable environment.
