The risk of an earthquake is stupidly low compared to the risk of you failing to get out of bed tomorrow morning, but so what? It's meaningless to compare the risk of Black Swan events. It's intelligent to mitigate risks when possible. We can't stop an earthquake (natural) or an oil spill (human errors), both happen regularly, but we can make the effort to better deal with them when they happen. The long-term failure to make the effort to do a better job at cleaning up oil spills is what has to change, and can change, but only if the public demands it. Government and industry have failed on this file for the last 50 years and there is no sign that things are about to change for the better. For example, there have been no changes since BP's DWH cleanup fiasco in 2010 when they only recovered 3% (three) of the oil and toxified the environment, to this day, with chemical dispersant (the oil did not "go away"as it was supposed to).
