Today I will discuss what I think are some cultural issues that are of interest to Poseidon. Note that I am taking “cultural” pretty wide as in “any issue faced by our modern day society”.
I think the number one biggest issue to Poseidon would be the immense amount of pollution of His domain. There are literally patches of human garbage, mostly plastic and other artificial substances, the size of small continents floating in the oceans of the world. And that’s just the most obvious, less obvious is the pollution that has made its way even down into the deepest oceanic trenches, including the very deepest of them all, the Mariana Trench. Not to mention oil spills and other chemical pollution from human activity. They constitute a great disrespect from humans towards their environment, in this case, the seas and oceans and waters of the world. Including rivers and springs, which get polluted through fracking and the dumping of industrial waste. He would vehemently support any initiatives to roll back this kind of pollution and to clean up the immense amount already caused and continually being caused.
Further of note to Poseidon would be the immense issue of overfishing, which threatens millions upon millions of people who rely on fishing for their livelihood or as part of their diet and who would starve without it. Not to mention that it threatens with extinction many denizens of His realm, that would not be in so dire a situation if it wasn’t for human overfishing.
In tandem with these two issues would be anthropogenic (human-caused) climate change, resulting in ocean acidification and warming oceans, which means countless species of sea-creatures are threatened because of their very habitat changing in ways they can no longer deal with. In turn, warmer oceans lead to more extreme hurricanes and other weather systems around the world, which will, in turn, lead to more extreme weather hitting coastal regions, threatening millions in yet more ways, threatening more violent erosion of coastlines, etc.
These, I believe, are the main issues Poseidon cares about in our modern times. Humans have been raging rampant for far too long, we can only hope the efforts to stop and reverse these will be in time to avoid complete calamity.
