Ofiservicios – The global food crisis essay

So far in this essay, mammals have received scant attention, but the mammals’ development before the Cenozoic is important for understanding their rise to dominance. The , called , first , about 260 mya, and they had key mammalian characteristics. Their jaws and teeth were markedly different from those of other reptiles; their teeth were specialized for more thorough chewing, which extracts more energy from food, and that was likely a key aspect of success more than 100 million years later. Cynodonts also developed a secondary palate so that they could chew and breathe at the same time, which was more energy efficient. Cynodonts eventually ceased the reptilian practice of continually growing and shedding teeth, and their specialized and precisely fitted teeth rarely changed. Mammals replace their teeth a . Along with tooth changes, jawbones changed roles. Fewer and stronger bones anchored the jaw, which allowed for stronger jaw musculature and led to the mammalian (clench your teeth and you can feel your masseter muscle). Bones previously anchoring the jaw were no longer needed and . The jaw’s rearrangement led to the most auspicious proto-mammalian development: . Mammals had relatively large brains from the very beginning and it was probably initially . Mammals are the only animals with a , which eventually led to human intelligence. As dinosaurian dominance drove mammals to the margins, where they lived underground and emerged to feed at night, mammals needed improved senses to survive, and auditory and olfactory senses heightened, as did the mammalian sense of touch. Increased processing of stimuli required a larger brain, and . In humans, only livers use more energy than brains. Cynodonts also had , which suggest that they were warm-blooded. Soon after the Permian extinction, a cynodont appeared that may have ; it was another respiratory innovation that served it well in those low-oxygen times, functioning like pump gills in aquatic environments.

Global Food Crisis (Global Crisis Series) – PlanetSave

When humans began to raze forests and use the resultant soils to raise crops, they were working their way down through the food chain, no longer harvesting ecosystem detritus but destroying entire ecosystems literally at their roots for short-term human benefit. That practice eventually turned forest ecosystems into deserts. As this essay will survey, that was a rampant problem in all early civilizations. Eventually, humans learned to reach even further back into the ecological horizon as they began burning energy stores that were hundreds of millions of years old; was first and second. They were burned a million times as fast as they were created. In all instances, humans were releasing sunlight energy that had been captured and stored by organisms. In the 20th century, when humans began using nuclear fission, they were going even further back in time and harvesting energy stored via billions of years ago. With each new energy source, humans were harvesting older, more concentrated energy sources, which released far more energy than the previously used source. In each instance, humans plundered the energy source to exhaustion. Humans have not lived in “harmony” with nature since they learned to control fire.

Readers for the collective task that I have in mind need to become familiar with the scientific process, partly so they can develop a critical eye for the kinds of arguments and evidence that attend the pursuit of FE and other fringe science/technology efforts. For the remainder of this essay, I will attempt to refrain from referring to too many scientific papers and getting into too many details of the controversies. Following my references will help readers who want to go deeply into the issues, and many of them are as deep and controversial as the Snowball Earth hypothesis and aftermath has proven to be, or attempts to explain the . These are relatively new areas of scientific investigation, partly due to an improved scientific toolset and ingenious ways to use them. It is very possible that the controversies in those areas will diminish within the next generation as new hypotheses account for increasingly sophisticated data, and in the near future are nearly certain. But science is always subject to becoming dogmatic and hypotheses can prevail for reasons of wealth, power, rhetorical skill, and the like, not because they are valid. The history of science is plagued with that phenomenon, and probably will be as long as humanity lives in the era of scarcity.

As will become a familiar theme in this essay, the rise and fall of species and ecosystems is always primarily an energy issue. The Ediacaran extinction is a good example: Ediacaran fauna either an energy source for early Cambrian predators, ran out of food energy, ran out of the oxygen necessary to power their metabolisms, or lacked some other energy-delivered nutrient. After the extinction events, biomes were often cleared for new species to dominate, which were often descended from species that were marginal ecosystem members before the extinction event. They then enjoyed a of relative energy abundance as their competitors were removed via the extinction event.

Essay on The Recent Global Food Crisis and Obesity …

Urbanization global food crisis essay

Could this essay's first half be considered an indulgence of my childhood fascination with nature? That argument could have merit, but I have always been a "big picture" kind of thinker, even as a teenager. I am writing this essay primarily to help manifest FE technology in the public sphere and help remedy the deficiencies in all previous attempts that I was part of, witnessed, heard of, or read about. The biggest problem, by far, was that those trying to bring FE technology to the public had virtually no support from the very public that they sought to help. My journey's most important lesson was that , and an egocentric humanity living in scarcity and fear is almost effortlessly manipulated by the social managers. John Q. Public is only interested in FE technology to the extent that he can immediately profit from it. Otherwise, he goes back to watching his favorite TV show. It took many years of disillusionment for that to finally become clear to me. While this essay and all of my writings are provided for free to humanity and anybody can read them, I intend to only reach a very tiny fraction of humanity with my writings, but that tiny fraction will be sufficient for my plan to succeed. The readers that I seek have a formidable task ahead of them, but nothing less is required for my approach to have any hope of bearing fruit. This essay and my other writings are intended as a course in (also called "big picture") thinking. Studying the details deeply enough to avoid misleading superficial understandings is also a key goal. I am an accountant by profession, but one of the world's leading paleobiologists surprisingly read an early draft of this essay and informed me that it was one of the best efforts that he ever saw on the journey of life on Earth. There was nobody on Earth whose opinion I would have respected more than his, so I do not think that I am asking readers of this essay's first half to humor me. Every sentient being on Earth should know the rudiments of what this essay's first half covers.

Another energy-related activity probably appeared on a large scale during the reign of dinosaurs: . Although territoriality , , , , and today, it is most common among birds and mammals. Territoriality is primarily about preserving an animal’s energy base from competition, and it is usually a behavior oriented toward others of the same species, which would eat the same food resources and mate with the same potential partners. Just as what scientists call , territorial behavior may go all the way back to the . But the social behaviors apparent in dinosaurs probably also meant territorial behavior, and probably on a scale never experienced before on Earth. Even the suspected display function of implies territorial behavior. All are territorial, and human political units such as are little more than ape territoriality writ large, as peoples protect their energy and mating bases. In light of the (with its apotheosis in the peacock, although, as usual, ), and the phenomenon perhaps goes , along with the discovery of dinosaurian mass nesting sites, herd behaviors, and the like, many scientists believe that .

Food Crisis Essay, Food Crisis Research papers

For several years before writing this essay, I have stated that the only inventor-oriented approach with a prayer is for an inventor with the goods (a viable prototype undoubtedly generating FE) to give it to a worthy group so that they can take it the rest of the way, past humanity’s inertia and any organized suppression activities that might be inflicted on the effort. I have never heard of the inventor with the goods willing to give it away, and that worthy group does not yet exist; my efforts could be seen as trying to help form it. Criticizing the inventor with the goods who is unwilling to give it away, when there is nobody worth giving it to, is unproductive.

Those attributes are far more easily described than achieved, but my essay is about developing them. The rest of this essay explores those issues in some depth. More than 30 years after I began dreaming of changing the energy industry, I to organize the thousands of reactions to the of FE that I have witnessed, and I will refer to it for the remainder of this essay. I have yet to find a reaction during my journey that does not easily fit into that framework’s categories.

I have written plenty about my days with and , and interested readers can discover more if they wish. I hope to convey what the learning experience of carrying their spears was like. My and comprised the kind of education that few survive for long. Although my education with Brian was far gentler, I learned important lessons from him. If not for my adventures, I would not have much worth saying. Even though much of this essay “merely” deals with mainstream science theory and data, . This essay is obviously not the work of a professional scientist, historian, or economist.
