You won’t hear an accountant mention pollution & accounting in the same sentence, but we are going to do so here, since we aren’t accountants. Garbage is what’s known as an economic bad, as opposed to most physical items, which are considered economic goods. Since garbage costs time and energy to remove, the possession of more garbage decreases the value of the one who possesses it. The phrase “throw it away” is misleading, comparable to fake news. Forget about diamonds – garbage quite literally is forever. We have nowhere to put it, so we resort to housing garbage in designated areas of our home planet Earth. As we continue generating this economic bad, garbage accumulation must result in a decrease in the value of planet Earth.

If you take a class in environmental science or search online, you’ll learn of the two rough categories of pollution:

Point and non-point source pollution —

Point-Sources

Point-source originates from a definite, identifiable source. Think of it as original pollution. Examples of point-sources:

– factories
– sewage treatment plants
– electric power generation
– oil & gas extraction
– oil & gas refineries
– coal mining
– coal fired power generation
– air pollution
– mobile sources & transportation (planes, trains, automobiles)

This San Antonio de los buenos pipe dumps over 20 million gallons of sewage into the Pacific Ocean every single day. Although the origin has been identified, there is nothing that has been done. A solution may cost hundreds of millions of dollars.

Humans, mammals, and creatures of every taxonomic rank experience pain. Illness affect us all, and each illness has the potential to reach a point of no return, at which point it becomes terminal for the organism. As of this moment, humans are inflicting a seemingly small amount of damage – analogous to an illness – on our earth via pollution. In an anthropomorphic sense, we are giving Earth a weakened immune system. It has the sniffles. As of now its not too late to get healthy. We can reduce the ill effects of pollution on our environment and atmosphere. And in doing so discover practices that promote a healthier Earth. Although not easy, we have to believe that it is possible. This is of utmost importance because if we aren’t careful, the small damages we are doing to earth may turn into something more serious. Its far easier to prevent lung cancer by refraining from smoking than it is to cure lung cancer after you get it. Likewise, it requires significantly more energy to clean up pollution than to prevent it. Prevention is better than clean up.

Non-point sources:

Non-point does not originate from a definite, identifiable source. It is a result of the diffusion of point-source pollution.

Run Off: Let’s look at an example. Think about the contribution of a cars in a city to non-point source pollution that accumulates on roads (let’s simplify by excluding air pollution from the equation).  in your city distribute substances (oil, gasoline, exaust, sludge, rubber, litter, debris, etc.) that accumulate on road surfaces. Individually, each car is a point-source. The aggregation of these chemicals being deposited by all 494,000 cars registered in San Francisco contributes to the category known as non-point source pollution.

Another example is runoff. The harmful chemicals that collect on any surface of earth, whether a road, parking lot, farm, originate at point-sources including cars, equipment, debris, agricultural materials, etc.

“When rain or melted snow moves over and through the ground, the water absorbs and assimilates any pollutants it comes into contact with.” (USEPA, 2004b)

Let us consider agricultural non-point sources, which are a result of the diffuse runoff that comes from the use of fertilizers, pesticides, or animal waste while growing crops and livestock.

Simple logic: to reduce the non-point source pollution that as a result of agriculture sources, we must stop it at the point of origin.

In this case, identifying each point source is too cumbersome and thus impractical… but we can paint a picture of what the point source associated with each non-point source generally looks like.

The pollution in the runoff example is the result of multiple locations over a period of days or weeks before rainfall, so you can’t pinpoint the exact source. Runoff is difficult to measure, identify, and control because it is the result of combined pollution sources that are received by the environment when water absorbs those chemicals which occurs over the entire surface of earth.

– land runoff
– precititation (acid rain)
– atmospheric deposition
– drainage
– leakage
– seepage (from underground storage tanks)
– hydrological modification (via rainfall and snowmelt)
– storm water runoff
– atmospheric deposition of contaminants, and
– storm water runoff from
– golf courses
– agricultural establishments
– forestry or construction sites

Acid Rain: Sulfur dioxide (SO2) and nitrogen oxides (NOx) enter the atmostphere when fossil fuels are burned at factories or by internal combustion engines. These chemicals can cause acid rain. Acid rain occurs when sulfur dioxide (SO2) and nitrogen oxides (NOx) reacting in the atmosphere with water; it then returns to earth as polluted rain, fog, or snow. Acid rain is considered non-point source. The originating source of acid rain are the multitude of point-sources sending smog into the atmosphere that combines with clouds.

After examining how we define point and non-point sources, logic will allow us to realize that by reducing all the point-sources, we will eliminate non-point sources of pollution from appearing. This of course does not include pollution that has already entered the atmosphere. What’s there is there unless we can do something to remove it. Reducing point sources of pollution will thus stop non-point sources of pollution from accumulating, but we will still have cleanup to do. However, for now, to make the largest impact, humans should focus efforts toward reducing point-sources.

Seems simple enough. But what happens when we try to track pollution to discover where it is coming from?

Can we track pollution?

It turns out that tracking pollution to a single source is difficult.

How can we determine the source of microplastics pollution, the material washing up on the far-stretching beaches of Zlatni Rat, Croatia? By first examining the materials themselves, maybe we discover that a large percentage of it is made up of specific types of materials – for instance, polystyrene (aka styrofoam).

Going with this example, after disposal, a piece of styrofoam will break up into 999,999 pieces pretty quickly. These tiny polystyrene particles may have come from a piece of packaging, part of a cooler, a styrofoam cup, you name it. We can consider existing ocean currents  in the Mediterranean and near Croatia to consider what may have sent it there. Because the Mediterranean is a semi-closed body of water, attaching to the Atlantic only through the strait of Gibraltar on the west and to the Red Sea via the Suez Canal on the southeastern side, we can hypothesize that microplastic particles existing there also originated there. The Mediterranean is more or less a closed system.

It is much more likely that the point-source origin is located somewhere along the coast of the Mediterranean sea. By narrowing it down, we can then try to estimate travel time to determine how long it may have taken to get from one place to another. We can think about ocean currents that may have sent it there. We can try multiple things to try to get a sense for where exactly all of the rubbish is coming from.

But ultimately, it is absolutely impossible to know where exactly plastics on the beaches of Croatia originated.

Scientists have categorized this as “non-point source” pollution because its origin is unknown. In a disorganized universe that follows the second law of thermodynamics, microplastics get lost in the clutter of the environment and atmosphere. Nobody can identify the source.

But these microplastics came from somewhere. So by convention, these pieces of microscopic polystyrene are considered non-point and separate from point-sources of pollution.

Non-point source pollution results from the disorganization and diffusion of all the point-sources of pollution combined through the environment. Non-point source pollution is “redundant source pollution”. Current technology is too incompetent to identify the point-source tied to every non-point source.

Accounting for pollution

In 1769, when James Watt patented the first steam engine. Voila, air pollution was amplified. With the growth of transportation technology as well as the human population since that date, pollution has progressively gotten worse as we’ve continued polluting the earth for at least 250 years.

Imagine for a second that we want to calculate how much pollution has ever occurred in the history of the world between now and forever-ago. To measure and account for quantity of those harmful substances in our environment, it would be helpful to differentiate between point and non-point because to avoid redundancy. Although an impossible feat in practice, to do so in theory, we would simply need to account for pollution arising from every single point-source in human history. By summing up pollution from each and every the point source ever, we would get an exact amount of total historical pollution (THP). We don’t need to factor in non-point source, because it would be counted twice.

(Point Source) + (Non Point source) > THP

THP is equal to the sum of all point sources of pollution from time = year 1700, to time = year 2018.

THP = ∑ (all point-sources of pollution) = Total Point-Source Pollution

Conclusion

Two broad types of pollution have been discussed briefly. When we consider which efforts will most greatly impact the future of humanity and help us create a clean, healthy environment, it can be hard to say which efforts are most effective.

The intention is not to say one category of pollution is worse or more benign than the other. The purpose is to identify the difference between pollution that has already entered the ecosystem, and pollution that is currently entering the ecosystem.

Before taking efforts to eliminate it, let’s realize there are different strategic purposes to reduction of each.

1. The value in eliminating non-point source pollution: stop pollution from diffusing and spreading to new areas, and remove old, existing pollution from our environment. Pollution that is already there.
2. Value in eliminating point-source pollution: prevent future pollution from entering out atmosphere and environment in the first place! Pollution that is entering the environment right now and into the future.

It is far easier to prevent a problem than it is to fix a problem.

In order to minimize human contribution to the pollution problem, humans must stop putting it into the ecosystem in the first place.

When calculating amounts of pollution, non-point source pollution has already been accounted for via the summation of all point sources. Point source pollution that has diffused throughout the environment can no longer be traced, so we duplicate it if we add them together. In theory, non-point source pollution is redundant and already accounted for, so we can essentially ignore it when accounting for how much pollution we create.

With enough thought and research, a point source can be broken down into its component point-sources. If you think you have a non-point source, ask yourself: What do I need to do to identify the original source?

Who has the power? The decision makers in the agriculture industry control what pesticides and fertilizers are used, as well as what happens to animal waste. In addition, every automobile manufacturer . on the business side of a a farm or agricultural facility. But as comsumers, we have the power to choose where our dollars go. Each dollar spent is like casting a vote for which business practices we will incentivize. If we purchase products that contribute to jit, we are playing our small but incremental role in the continuation of

For the future of our species, we must be focus on identifying point-sources in order to reduce the amount of pollution at its origin, rather than after-the-fact removal. If you are interested in discussing this further, please contact us.
