Algae blooms in Florida are a manifestation of a much larger problem.

Algae blooms are not unique to Florida. While nutrient pollution potentiates blooms in all 50 states[i] and in countries around the world, one could argue that, at some point, differences in degree become differences in kind.

Baltic Sea - Gulf of Finland

Florida – a difference in kind?

There are some unique circumstances in Florida that may support that argument. Lake Okeechobee has served as a catch basin for nitrogen-rich fertilizer runoff for decades, and it is an ideal incubator for blue green algae. Southwest Florida managers have little choice but to discharge the algae-laden water to the rivers and estuaries to the east and west when lake water levels threaten the integrity of Herbert Hoover Dike.

Citizens and activist in Florida are right to hold polluters and government officials accountable for the problem and to seek all possible remedies. However, addressing the issue will be a daunting challenge with no near-term solution in site.

Part of the challenge is that the problem has been brewing for decades. The University of Florida estimates that even if all farming were to stop today, there would be enough residual nitrogen and phosphorus nutrients remaining in the soil to feed blooms for the next 50 years.[ii]

Algae is one of many canaries

And then there is the real catalyst for blooms around the world that may take centuries to be solved – global warming.  If past is prologue regarding nutrient pollution, then it’s possible that humans will be able to address agricultural nutrient pollution in a way that detergent phosphate pollution was addressed in the 1970s. It’s possible, but realistically, I don’t think it’s probable.

Agricultural nutrient pollution is likely not going to be solved by a single legislative act. It’s easier for Americans to use phosphate-free laundry detergent than it will be for them to pay a bit more for ubiquitous refined sugar. Plus, the ranching and sugar lobbyists are likely more effective than any phosphate lobbying groups in the 70s.

The temporal myopia of humans

The real challenge in addressing catastrophic problems is that humans don’t recognize the magnitude of the problem until it impacts their daily, transactional life. We impatiently expect to resolve in months what has taken decades or centuries to develop. I considered this human characteristic in a 2015 blog post – “Obliviousness to global catastrophes- if we can’t feel it, it simply doesn’t exist.”[iii] I think algae blooms are just one of many examples of how our species is incapable of acting on a daily basis with anything resembling long-term vision.

If we were capable of thinking beyond the next Facebook posting or past the next critically important tweet (an oxymoron if ever there were one) we’d be able to see that humans are truly killing the planet. Not next century, not the next decade, but now. Right now. If you’ve read this far, I encourage you to take a brief moment and look out the window. What do you see? You probably see the hum and buzz of daily life. But, if you look beyond that, what you’ll see is that you very well may be looking at the sixth mass extinction on planet earth.

Some scientists have argued that we are currently in the midst of the Holocene extinction event. I’ve pondered the probable role of human production of carbon dioxide as a main contributor factor to a mass extinction in “The Holocene extinction event. Is our species’ destiny to be known as “The Burners?”[iv]

So, our challenge as a species is to discover a way to find long-term solutions to problems created by our propensity to live in the moment, do what feels good, and maximize personal and corporate wealth. Not to be overly pessimistic, but my guess is that we, as the dominant species on earth, will fail. All is not lost. The earth will go on long after the human experiment has run its course.

My optimism for the planet, but not our species, was noted in 2014, “Humans are a minor perturbation in the life of the earth.”[v] Unfortunately, I believe that is still the case. Even more so as the United States under the current administration continues to eviscerate environmental regulations.

Minnesota Botanical Studies, Volume 3, 1903-1904

“An endeavor has been made to collect some of the more important known facts concerning “water bloom” as it occurs in Minnesota and neighboring states. It seems quite certain that at least some of the algae causing this appearance in water supplies are of considerable sanitary importance.”

Coal Consumption Affecting Climate- Rodney and Otamatea Times, Waitemata And Kaipara Gazette, 14 August 1912

“The furnaces of the world are now burning about 2,000,000,00 tons of coal a year. When this is burned, uniting with oxygen, it adds about 7,000,000,000 tons of carbon dioxide to the atmosphere yearly. This tends to make the air a more effective blanket for the earth and to raise its temperature. The effect may be considerable in a few centuries.”

““It was gluppy — like green latex paint,” said engineer Edwin C. Web er of the Maryland Department of Water Resources, who was sent to investigate after Burgess complained. But this was only the first stage of the disaster. Because there was so much of the Anacystis—and because the algae were bloated with nourishment flowing down the river from the sewers of Washington—they began to die.”

“Changes in the flora and fauna at Loch Leven are described. Species associated with oligotrophic conditions such as charr and desmids have declined or disappeared, and prolonged, dense algal blooms, particularly Cyanophyceae, have been a feature of recent years. Much of the macrophytic vegetation has disappeared and there have been changes in the composition of the zooplankton and benthos, several abundant species disappearing…”

Are farmers’ profits more important than our water?

Obliviousness to global catastrophes- if we can’t feel it, it simply doesn’t exist.

I am convinced that one of the limiting factors of the human species is our inability to understand cataclysmic events that are occurring because they develop at a rate that is outside our ability to emotionally comprehend. And, as humans, if something can’t be understood at an emotional level, then it is unlikely to receive the attention it deserves.

I have written before about the Holocene extinction, a cataclysmic event through which we are very likely living.[1] Everyone look around. Does it look like we’re in the same predicament as the dinosaurs and are about to become extinct?  Admittedly that’s a hyperbolic question.  And, the expected answer is a resounding “No. Everything looks normal.” However, we need to remember that after that asteroid slammed into the earth, it took the dinosaurs another 30,000 years to die out. And yet, when one visualizes the extinction of the dinosaurs, the vision is one of near-immediate obliteration. Actually, that’s an accurate characterization if one is thinking in geologic time.

Our perception of the extinction of the dinosaurs is that it occurred rapidly and catastrophically, but it actually took 30,000 years for the dinosaurs to die out after the meteor strike. How we perceive the sixth great extinction, the Holocene Extinction. We don’t really perceive that we are living during a mass extinction because the cataclysmic events occurring around us are happening at a rate too slow for us to feel.

The guiding clock of a human is not based on geologic time, but on what we experience in our daily lives. Intellectually, we can observe and understand long term events, but we aren’t likely to act on them because they fall outside the collective consciousness of our species.[2] If a dinosaur hatched 5,000 years after the meteor strike and could ponder such things, what would it think while looking around munching leaves? Not much, within her mind everything would seem normal; she wouldn’t see any mass extinction. The most likely thought would have been, “Where’s my next leaf?”

If we are in the midst of another great extinction, then we won’t see it either. Not because it’s not happening, but because it is happening at a rate that is too gradual for us to feel and experience. We’re too busy looking for the equivalent of our next leaf. It’s not just the Holocene extinction that we have trouble seeing. There are other events occurring around us that portend disaster, or at least extreme discomfort, for our species to which we are oblivious.

I remember a few years ago reading about the thermohaline circulation- the great oceanic conveyor that moves warm water from the Gulf of Mexico northward toward the United Kingdom[3]. I was struck at the time not only by the elegance of the system that kept Northern Europe relatively temperate, but also by its fragility. It has been widely suggested that the perturbation and subsequent shutdown of this system was what lead to the Little Ice Age 10,000 years ago and that a subsequent shutdown would lead to another big chill in Northern Europe.[4] Climate scientists believe this transition could take place in a matter of a few years – not a few centuries.  Such is the nature of tipping points.

Recent evidence suggests that the disruption of the thermohaline circulation has already begun. Chris Mooney wrote about this possibility recently in the Washington Post and offered the following map from NOAA as suggestive evidence. [5] The map shows anomalous record cold in the Northern Atlantic at the terminus of the thermohaline circulation.[6] Does this corroborate the suggestion that the great conveyor has started its collapse? Maybe, maybe not, but it is highly suggestive that something not normal has been occurring recently.

What does all this really mean? Maybe a few tens of thousands of years from now whatever sentient beings exist will look back and wonder how we humans could have been in the midst of such catastrophic events and taken no action to alter the course of our future. It is surely within our intellectual grasp to do so, but we will not. Instead, we live our daily lives consumed by the minutia of the present minute. We will be driven by our primitive emotion-based compass to pursue the fleeting distractions of the hour. We will fight over land, go to war over religion, fight over sexual orientation, argue endlessly of funding social programs, debate spending obscene amounts of GDP on the military and its methods of mass destruction, wonder what the Kardashians are doing, or fight about restricting firearms intended only to kill humans.

It would be so glaringly obvious that all of these pursuits are so incredibly meaningless if we could only understand, no, if we could only feel that the events of our world do not follow humans’ perception of time. If we look closely and critically we can see the events unfolding, but because we can’t feel them, the odds of our taking any meaningful action is, unfortunately, quite remote.

Inevitably, we are part of this world and whatever we do is all that we can do. Our logical and intellect may not outlive the consequences of our emotional behaviors. Humans will be humans, and in 100,000 years or so, the Earth will have sorted things out one way or another- with or without the assistance from humans. The only question is if our species will be around to see how things turned out.
