One major problem with making a positive impact on a global level, ultra-elite machinations aside, is that almost nobody focuses on what is important, which I hope to help remedy with this essay. Almost everybody hacks at branches if they hack at all. Conspiracists tend to obsess on elite machinations, which is an exercise of dubious benefit to begin with, but they often become paranoid and also confuse retail elites or other interests with the GCs. Bill Gates and David Rockefeller are probably not members of the GCs’ organization. Also, I learned that ultra-elites can only play their games with the responsibility that almost all people have abdicated as they play the victim. The GCs are only a symptom of our malaise, not a cause. They cannot be beaten at their game, and it is counterproductive and can even be suicidal to try. Making them obsolete is probably the best that we can do. While conspiracists often fixate on ultra-elite machinations, intellectuals, academics, and scientists tend to deny that such activities even exist or are meaningful. It took me many years to understand their resistance to even acknowledging ultra-elite existence, and I think it partly relates to the mainstream scientific worldview that . They have an ideological aversion to the notion that anybody manipulates events on a global scale, and believe that what seems conspiratorial is only anarchic elites competing with each other, which is like Darwin’s view of evolution. They believe that conspiracists see a pattern where none exists, or that the situation can be explained without invoking conscious intent, like materialistic hypotheses of how the universe operates. Radical leftists have to the of such elites; such an idea scares them. Neither obsession nor denial helps people attain productive understandings of the issue. Conspiracists and structuralists are united in thinking like victims, and that, as I see it, . Until they relinquish thinking like a victim, they will not constructively engage the critical issues that humanity faces, and energy ranks above all else. Victims are reactive instead of proactive, and only and resulting action has a prayer of working, in my opinion.
The Cambrian Explosion had several phases to it, with explosions of life and mass extinctions, and a general atmospheric oxygen rise accompanied it. Anoxic conditions coincided with extinctions. would not be that affected by what complex life was doing (although anaerobes were generally driven underground and into the seafloor), but the rise of complex life led to new ecosystems. Before the rise of animals, the seafloor was smooth and “stiff,” but burrowing animals had profound impact on seafloor ecosystems and may have played a prominent role in creating the ecosystems themselves. Corals created new ecosystems, as life terraformed Earth.

Specialists are often those on the ground, getting their hands dirty and doing the detailed work that forms the bedrock of scientific practice. Without their efforts, science as we know it would not exist. However, mainstream science has long suffered from the tunnel vision that overspecialization encourages, and thought that the epidemic overspecialization and in his time and unable to see the forest for the trees. That has been slowly changing in my lifetime, so that collaborative efforts are drawing from multiple disciplines and achieving synthetic views that were not feasible in earlier times, and patterns are newly recognized that were invisible in a scientific world filled with isolated specialists. Many were made by non-professionals, specialists working outside of their field of professional expertise, and generalists traversing disciplinary boundaries. Scientific training today attempts to prevent that overspecialized tunnel vision, and today’s practicing scientists ideally get deep into the details and then pull back and try to see context, connections, and patterns. A comprehensivist tries to understand the details well enough to refrain from making unwarranted generalizations while also striving for that big-picture awareness. There are also to approach analyses; each can provide critical insight, and scientists and other analysts often try to use both.
Another key set of tensions are those between theorists, empiricists, and inventors. Theorists attempt to account for scientific data and ideally predict data yet to be adduced, which tests the validity of their hypotheses and theories. often produce that scientific data. Inventors create new technologies and techniques. Albert Einstein is the quintessential example of a theorist, who never performed experiments relating to his theories but accounted for experimental results and predicted them. , who performed the experiment that produced results that various scientists wrestled with for a generation before Einstein proposed his , never suspected that their experiment would lead to the theories that it did. The most important experiments in science’s history were often those producing unexpected results and were usually called failures. Einstein’s had no experimental evidence when he proposed it (it , but that was the only evidence for it when the theory was proposed), but it has been confirmed numerous times since then. Einstein expected that his theories would eventually be falsified by experimental evidence, but that the best parts of his theories would survive in the new theories.

Were the dramatic changes in a result of cooked food, or was Turkana Boy as his species became hunters instead of hunted, and the stone tools softened up the meat and plant foods so that he did not need to chew as much? Wrangham co-authored a that began with . It concluded that food processing, cooking in particular, accounted for the effect. Cooked food versus raw food and the number of neurons that can be supported in a brain has been . The primary reason why Wrangham’s hypothesis was initially dismissed was that archeological evidence for fires that long ago is almost nonexistent. When was published, the earliest evidence with wide acceptance only supported fires , where Israel is today, which is more than a million years after Wrangham’s estimated timeframe. Wrangham did what all bold scientists do: he made falsifiable predictions. If it turned out that no evidence of early fires was ever found, his hypothesis could begin looking shaky.
The derision was loud from Wrangham’s colleagues…until evidence of was found at in South Africa by using new tools and techniques. The chortling is subsiding somewhat and scientists are now looking for the faint evidence, and long-disputed evidence of 1.5-1.7 mya controlled fires is being reconsidered, although his hypothesis is still widely considered as being only "mildly compelling" at best. New tools may push back the control of fire to a time that matches Wrangham’s audacious hypothesis. Wrangham cited the Expensive-Tissue Hypothesis as partially supporting the Cooking Hypothesis, but , the energy to power the human brain may not have solely derived from cooked food’s energy benefits. Wrangham has cited numerous lines of evidence, one of which is a that has to find honeybee hives and smoke them out; the humans get the honey and the honeyguide gets the larvae and wax. According to recent molecular evidence, the evolutionary split of the honeyguide from its ancestors happened up to three mya, which supports the early-control-of-fire hypothesis. There is great controversy regarding these subjects, from recent findings that to scientists making arguments that to the social impacts of campfires. This section of this essay will probably be one of the first to be revised in future versions, as new evidence is adduced and new hypotheses are proposed.

Mesoamerica’s Domestication Revolution was one of the two certainly pristine ones known, and the one around today’s Peru may have been another. The other two of the human journey arose there, and they followed the same general patterns as Sumer and China in that they began peacefully with no classes and, as they grew into states, men came to dominate, elites appeared with monumental architecture devoted to them, potentates had harems and divine sanction, and there were other features that seemingly evidenced universal human traits and/or reactions to similar conditions. The development of religion in what became Mesoamerica’s pristine civilization, the , has been documented by archeologists who traced a seven-thousand-year progression from hunter-gatherers to egalitarian early agriculturists to an elite-dominated society to a pristine state. It was similar to how Mesopotamian civilization developed, including the (today’s rock stars have been likened to the new shamans, as their concerts revive pre-civilized gatherings and rituals). Controversial aspects of Mesoamerican societies have included human sacrifice and cannibalism. They definitely happened, and human sacrifice was practiced on a pretty grand scale at times. The question of Western Hemispheric cannibalism has touched on the lack of domestic animals, so it may have had nutritional aspects, or what is called culinary cannibalism. But most seeming cannibalism is of the cultural cannibalism variety, in which eating flesh has symbolic meaning, whether it is eating somebody to keep their spirit in the family/tribe or to gain spiritual dominance over a fallen foe. Cannibalism was a common charge made against peoples that Europe conquered, but was usually a sensational allegation to remove their humanity and justify their bloody treatment by Europe. Columbus made his from whole cloth.
Ideas for an Essay on Renewable Energy or Alternative Energy Essay
After newly exposed forest soils have produced a few crops, the yield will decline due to nutrient depletion. When the croplands receive less precipitation, yields drop. When soils wash away due to erosion, crop yields in those eroded soils will decline. Those effects reduce the EROI and surplus energy of farming those lands. When cropland is abandoned due to aridity, nutrient depletion, and erosion, and lands farther from Rome were conquered, deforested, and farmed, it took more energy to transport those crops to Rome than with farms closer to Rome. That also depressed the EROI and surplus energy. When harbors silted up and needed dredging, or were eventually abandoned and a port was built farther away, that also reduced the EROI and surplus energy of Rome-bound food. When food was used to feed soldiers who traveled increasingly vast distances to conquer and plunder peoples and their lands, those would be lower-EROI ventures than conquests closer to Rome. That dynamic has also been called in academic parlance, but in scientific terms, it is really just sucking the dregs of low-EROI resources after high-EROI energy sources have been depleted. Rome’s decline was really just another resource-depletion dynamic. Humanity’s first one was , and Rome only experienced what , , , , and numerous other early civilizations already suffered. Rome just did it on an unprecedented scale.
