Warmer Seas Blocking Nature’s Carbon Pump
Diatoms are one of the most common types of phytoplankton.
Climate change isn’t just warming the atmosphere, it’s also warming the ocean’s surface and deeper levels of the water column. This is known as the pelagic ocean (the “pelagic zone” is any part of the water column other than that at the sea floor) and it just so happens to harbor the most productive ecosystem on planet Earth. The pelagic ocean is responsible for an estimated half of the world’s primary production (i.e., the basic food or nutrient making needed to sustain other life), and sustains most of the world’s natural fisheries.
The pelagic zone also plays a very complex but important role in the global carbon cycle. Inorganic carbon (mostly in the form of CO2) can be “drawn down” from the atmosphere by two main processes: the respiration of photo-synthetic algae and plankton (which produce oxygen and serve as a food source as well), and, secondly, the sedimentation of carbon (in the form of sinking, dead marine matter) onto the sea floor. Most algae and phytoplankton have chlorophyll and live in the upper most layer of the water column where there is sufficient sunlight penetration (this is called the euphotic zone; from the surface down to 200 meters is the epipelagic zone). Although carbon is also removed via “outgassing” (the exporting of carbon and carbon-based molecules into the atmosphere via ocean-air circulation), these two processes keep carbon out of the atmosphere. And of the two, bottom accumulation (via sinking) is the predominant means by which carbon is removed from the water column.
Did Diet Coke Cause My Cancer?
Recently I have been reading very disturbing research about how Diet Coke can possibly cause cancer and kill you. The artificial sweetener that is used in most diet beverages, aspartame, once ingested, becomes a lethal poison called methyl alcohol. Small quantities of this noxious substance can lead to blindness and death; even the most miniscule amounts of this aspartame toxin are strongly linked to cancer.
This is an image of the cancerous tumor that was recently removed from my body.
Are Large, For-Profit Corporations Intrinsically Less Ethical?
In the comment streams on my blog posts there is a recurrent theme from one segment of the respondents - they have a deep distrust in the large companies that are involved in modern agricultural technology. They don’t believe these companies will behave ethically because they are for profit entities “only answerable to their shareholders.”
I’d like to speak directly to this as a long-time Ag industry insider whose experience does not support these suspicions. I know that some will dismiss this perspective assuming I am biased, but one has to balance potential for bias with actually having first-hand experience from which to speak. Over the last 32 years I’ve work for or with most of the companies, large and small, that provide agricultural technologies. Fourteen of those years have been as an independent consultant so I get to know what is going on inside of many companies in a given year. I have still only had direct knowledge of a subset of what happens, but in all of that exposure I’ve never witnessed an unethical decision or action - not even the consideration of one. I’ve seen certain decisions that were short-sighted. I’ve sometimes seen decision-making processes that are more driven by fear than by opportunity. I’ve seen missed opportunities because vision was lacking. I’ve occasionally seen failures to take advantage of synergies that could have been realized between divisions of large organizations. I’ve seen problems, but I believe that some level of dysfunction is inevitable in any organization involving people. Still, unethical behavior isn’t something I’ve seen so I disagree that it is automatically likely just because of the characteristics of the company.
On balance I’ve also seen these organizations, large and small, frequently make important contributions to society in terms of the productivity and safety of our food supply. I’ve seen these companies continue to do that in an environment of constant activist attack and very limited public understanding because so few people farm.
