Somewhat surprisingly, since we are land based mammals, we find that 71% of the earth is actually water, and not land. This has led to an unfortunate mindset of which because there appears to be an endless amount of water, that far exceeds our land mass, and in the knowledge that oceans and rivers, are not stagnant, but are typically free flowing -- of which there is therefore an expressed understanding that dangerous chemicals, garbage, and waste that deliberately or inadvertently are deposited within these rivers and oceans, will in most cases, travel from one place to another place, all of this together contributes to the rather shameful way our waterways are typically dealt with. This means, that unlike those that bury their waste into a given landmass which pretty much does not move, that for those that are polluters, there are immense advantages in discharging one's waste into water, because of the flow of that water, which thereby makes it more problematic to positively identify those that are the polluters, but also provides a means that allows those polluters to do so in a manner, in which that pollution, typically travels elsewhere and away from them.
So then, rivers and oceans, from time immemorial, have been utilized as waste depositories, for all sorts of civilizations and those enterprises so created from such. However, never has this world been as modernized as today's world has become, of which some of those items so polluting our waters, are specifically manmade products, such as plastic, which do not biodegrade very well; in addition, to manmade chemicals that are being discharged into our waters, all in the process of making various products to be sold and produced for profit and for our benefit. Further to the point, while some of the pollution in our waters are clearly visible to our eyes, and the effects of such, quite obvious; there are plenty of chemicals so discharged into our waters, that are often not visible to the eye, but are incredibly devastating to not only the animal life that supports itself upon those waters, but human life, as well -- that is thereby caught unawares utilizing such water under the belief that it is clean and wholesome, when it is not.
There are laws that in theory, deal constructively with the pollution so being discharged, and of which, there are rules and regulations to deal with those dangerous chemicals and other pollutants; but when these laws and regulations are either not effectively enforced, or are circumvented via one way or another, it is our rivers and oceans that are hurt, along with life, itself. There has to be fair balance that recognizes the value and necessity of good water, weighed against the advancements of this modern age. Further, because one country or its domestic institutions can create pollution in one spot, but through the currents of oceans and rivers, such pollution can easily affect in a negative manner, some other country and its people, there has to be the means to deal with those that harm the commons that each of us has a natural right to be beneficiaries of.
For the health of our world and the peoples that make up this world, there needs to be more responsibility taken by those that deal with that which creates a byproduct of pollution, of which these institutions need to be held accountable for their actions; for our oceans and rivers are not fair hiding places for bad actions that are ill conceived by those that should fairly answer for that which they have done, without having taken proper account of the impact of such, as well as their willful failure to do the right thing.
