So how has photography changed the world.
From about 32 kya to 22 kya, prevailed in Europe. That culture produced the and art such as the . By 20 kya, . But as far as human expansion is concerned, the Gravettian (and related cultures) are most notorious as mammoth hunters extraordinaire for those that lived on the near the ice sheets. To , they could not swim to Sahul, but flourished everywhere else they could get to. At , they were the ultimate hunter-gatherer kill. Also, near the ice sheets, meat could be stored in the ground. Cro-Magnons did just that, and that “freezer” full of meat led to the first seasonally sedentary humans. It long predated the Domestication Revolution when people could be sedentary year-round, but while the megafauna lasted, the first signs of what came later appeared as Cro-Magnons created villages around frozen mammoth meat. Gravettians hunted along migration routes and set traps and ambushes for mammoths. For thousands of years, mammoths were the primary focus of Gravettian hunters, and many scientists believe that humans at least . Gravettians probably used the bow and arrow, and using poisoned arrows on mammoths would have been child’s play, not a hazardous undertaking. They also tended to focus on the easy meat: the young, relatively defenseless, tender mammoths. Killing the offspring alone would have driven the slowly reproducing mammoths to extinction, and as the interglacial period began around 15 kya, there would have been new pressures on mammoths. One of them was that fewer mammoths meant that they were not terraforming their environments like they used to, and the warming climate probably reduced their range. For a mammoth facing humans, there was literally no place to hide (except maybe in the living room), and there is little reason to think that hunters would have eased up when mammoth numbers dwindled. If anything, their efforts would have to get the last ones, as they competed and fought over the final mammoths. In one lifetime or even several, the changes would have been barely noticeable, if at all. There was simply no way out for mammoths, and they went extinct south of the European ice sheets under the ministrations of Cro-Magnon hunters. More evidence of their fate is some mammoths surviving in refugia: islands where humans did not arrive until thousands of years later. mammoths survived on in the chain off of Alaska until less than six kya, and went extinct when humans arrived. Several hundred apparently full-sized mammoths survived on near Siberia and went extinct less than five kya, when humans arrived. In today's France and Spain, Gravettians also semi-settled along the migration routes of reindeer and red deer. From Spain across Europe, into today's Russia, Gravettians hunted migrating herds, and not only the mammoth was driven to extinction, but also the wooly rhino, the Irish elk, the musk ox, and steppe bison were driven to extinction as the ice sheets retreated. Neanderthals had been ambush hunting in similar fashion, and those animals, like the African megafauna, grew wary of humans, and killing those animals probably took planning and guile.
Because of this ever-increasing global interaction, between 1750 and 1870 momentous changes occurred across the world in agriculture, politics, economics, and technology.
The World War Two era was a time of change.
Two primary events drove the first phase of the Ordovician-Silurian mass extinction: the ice age caused the sea level to drop drastically and the oceans became colder. When sea levels fell at least 50 meters, the cooling shallow seas receded from continental shelves and eliminated entire biomes. Many millions of years of “easy living” in warm, shallow seas were abruptly halted. Several groups were ravaged, beginning with the plankton that formed the food chain’s base. About 50% of brachiopod and trilobite genera went extinct in the first phase, and cool-water species filled the newly vacant niches. Bivalves were largely found in seashore communities, were scourged when the seas retreated, and lost more than half of their genera. Nautiloids were also hit hard, and about 70% of reef and coral genera went extinct. The retreating seas somehow triggered the extinctions, and whether it was due to simply being exposed to the air or changing and cooling currents, nutrient dispersal patterns, ocean chemistry, and other dynamics is still debated, and those extinction events are being subjected to intensive research in the early 21st century.
After as little as a half-million years of bedraggled survivors adapting to ice age seas, the ice sheets retreated and the oceans rose. The of the time may have also changed, and upwelling, anoxia, and other dramatic chemistry and nutrient changes happened. Those dynamics are suspected to be responsible for the second wave of extinctions. There also seem to have been .Atmospheric oxygen levels may have fallen from around 20% to 15% during the Ordovician, which would have contributed to the mass death. Seafloor anoxia seems to have been particularly lethal to continental-shelf biomes, possibly all the way to shore. It took the ecosystems millions of years to recover from the Ordovician-Silurian mass extinction, but basic ecosystem functioning was not significantly altered in the aftermath, which is why a has been proposed as a more significant extinction event. The were laid down by the . Most oil deposits were formed in the era of dinosaurs and the processes of oil deposit formation were similar; they were related to oceanic currents. When currents came to shore via the bottom and the prevailing winds blew the top waters offshore, it became a and anoxic sediments could form. When the winds blew onshore and left via the bottom, the waters became clear and are known as nutrient deserts. The oscillation between nutrient traps and nutrient deserts can be seen in oil deposit sediments. In the mid-20th century, Soviet scientists revived an old hypothesis that oil was , a variation of which was also championed by , but improving tools and investigation invalidated those hypotheses. No petroleum geologists today seriously consider the abiogenic origin of hydrocarbons. Oil sediment formation events seem related to mantle and crust processes that created high sea levels and anoxic events, and the last great one was in the , which formed more than 10% of the world's oil deposits.

Illustrious Russian author, Leo Tolstoy, pondered the survival of the Jews, but also sensed that their existence had to do with a unique purpose: “What is the Jew?…What kind of unique creature is this whom all the rulers of all the nations of the world have disgraced and crushed and expelled and destroyed; persecuted, burned and drowned, and who, despite their anger and their fury, continues to live and to flourish? …The Jew is the symbol of eternity. … He is the one who for so long had guarded the prophetic message and transmitted it to all mankind. A people such as this can never disappear. The Jew is eternal. He is the embodiment of eternity.”
You can unite only on the basis of disdain of gentiles. Nothing else you have in common, within your own nation. You disdain each others, too, but you disdain gentiles much more.
That is why you have abandoned your own country (you could not live together), and have spreaded throughout the world. In smaller communities, among gentiles, you could tolerate each other, and cooperate.
Your problem will have to be solved, because you make it to be our big problem. You have spoiled/deviated everything, starting from the origin of Kabbalah, via world-economy, and up to the fundamental physics.
You are evil. You cannot cure yourself. You see yourself as the best, in everything, so you are incapable to see yourself as you really are. Your kids should be taken from you, and raised by reasonable, good gentiles. There is, unfortunately, no other way. There is, actually, but it is not human (i.e. that what Hitler tried, and he tried that because he was, in his mind, the same as the Jews: he considered himself and his nation as superior-race).

The rise of oil was the other radical energy event of the late 19th century. Rockefeller’s empire was originally built on replacing whale oil for lighting, but Edison’s light bulb soon ended that need, and little did Rockefeller suspect it, but oil’s big days were just ahead. Oil is the world’s most coveted resource for a few reasons. are near-solids in partial-lattice states, in which the temperature () is high enough so that lattices continually break and reform. Raise the temperature higher, and those partial lattices disintegrate and the liquid becomes a gas. Solids cannot flow, and liquids are far denser than gases, so a liquid energy resource will be far superior to a solid (coal) or gaseous (natural gas) fuel. A metric ton of oil contains nearly twice the energy of a metric ton of coal and can be pumped through pipes. Until World War I, most ships and trains were powered by coal (by the late 19th century, some boats and trains used oil, but they were a distinct minority). In 1769, as Watt was working on his first steam engine, a , and coal-powered cars were the standard until . and also existed in those early days, but oil was quickly seen as a superior fuel for those reasons stated above, and Henry Ford’s company, , quickly led to the dominance of oil-powered cars. The in 1903 with anything other than an oil-powered engine.

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.
