Crea un quiz basandoti sul seguente testo: La Repubblica Popolare Cinese (中華人民共和國T, 中华人民共和国S, Zhōnghuá Rénmín GònghéguóP ascolta la pronuncia in mandarino standardⓘ), detta anche solo Cina (中國T, 中国S, ZhōngguóP; lett. "Paese di mezzo"),[7] è uno Stato dell'Asia orientale. La Repubblica Popolare Cinese è stata in passato indicata come Cina popolare, al fine di distinguerla dalla Repubblica di Cina, comunemente chiamata Taiwan (o Formosa), indicata invece come Cina nazionalista. Entrambe le entità reclamano il controllo sul territorio complessivo cinese. La Repubblica Popolare Cinese con 1 miliardo e 400 milioni di abitanti nel 2023 è lo stato più popoloso del mondo insieme all'India.[4] La Cina è una repubblica popolare in cui il potere è esercitato dal Partito Comunista Cinese (中国共产党 oppure 中共). Il governo ha sede nella capitale Pechino (北京首都) ed esercita la propria sovranità su ventidue province (省), cinque regioni autonome (自治区), quattro municipalità direttamente controllate (直辖市) (Pechino 北京, Tientsin 天津, Shanghai 上海 e Chongqing 重庆) e due regioni amministrative speciali 特别行政区 (Hong Kong 香港 e Macao 澳门) parzialmente autonome. La Cina rivendica la propria sovranità anche su Taiwan, che a propria volta rivendica la propria sovranità sulla Cina continentale. L'isola è rimasta dal 1949 sotto il controllo del governo della Repubblica di Cina (中華民國 o Taiwan), che precedentemente governava anche la Cina continentale, ed è rivendicata dalla Repubblica Popolare Cinese come provincia di Taiwan. La complessa condizione politica di Taiwan è una delle conseguenze della guerra civile cinese, che ha preceduto la fondazione della Repubblica Popolare Cinese. Con la sua superficie di circa 9 572 900 km², la Cina è il quarto stato più grande del mondo per superficie. Il paesaggio della Cina è vasto e diversificato: va dalle steppe della foresta e i deserti dei Gobi e del Taklamakan nell'arido nord alle foreste subtropicali e umide del sud. L'Himalaya, il Karakorum, il Pamir e il Tian Shan sono le catene montuose che separano la Cina meridionale dall'Asia centrale. Il Fiume Azzurro (长江) e il Fiume Giallo (黄河), rispettivamente il terzo e il sesto più lunghi del mondo, scorrono dall'altopiano del Tibet verso la costa orientale, densamente popolata. La costa della Cina lungo l'oceano Pacifico è lunga circa 14 500 chilometri ed è delimitata dal mare di Bohai, dal mar Giallo, dal mar Cinese Orientale e dal mar Cinese Meridionale. L'antica civiltà cinese, una delle più antiche al mondo, si sviluppò inizialmente nelle pianure comprese tra il Fiume Giallo e il Fiume Azzurro. A partire dall'età del bronzo, verso la fine del II millennio a.C., si ha evidenza di strutture feudali, in cui i nobili si raccoglievano intorno a monarchie ereditarie. Vi sono testimonianze di una casata regnante nella prima metà del I millennio a.C., nota come dinastia Zhou (周朝), il cui declino condusse alla nascita di un discreto numero di regni indipendenti in competizione per il predominio sulla regione (periodo delle Primavere e Autunni, 春秋), con stagioni di conflitto che si fecero particolarmente accese nel periodo che va dall'VIII al III secolo a.C. Nel 221 a.C. lo Stato di Qin sconfisse e conquistò i territori di tutti gli altri Stati combattenti, dando vita al primo impero della storia cinese sotto la guida del primo imperatore cinese Qín Shǐ Huángdì della dinastia Qin (秦朝). Da quel momento il titolo di imperatore della Cina divenne il sinonimo della raggiunta supremazia. La dinastia Qin non durò a lungo, infatti i popoli precedentemente conquistati vennero poco dopo riuniti sotto l'egida della dinastia Han (汉朝, III secolo a.C. - III secolo d.C.). I quattro secoli in cui regnarono i sovrani della dinastia Han sono considerati cruciali per la definizione e l'affermazione della identità culturale cinese, tanto da divenire il termine con cui i cinesi definirono se stessi (con il termine appunto di etnia o popolo han, 汉族). Da allora, la storia cinese ha visto l'alternarsi di periodi di divisione e fasi di unificazione, con conseguenti periodi di frammentazione, contrazione o espansione territoriale, sotto l'egida di diverse dinastie, talora di etnia straniera, come avvenuto nel caso dei mongoli o dei mancesi. L'ultima dinastia fu quella dei Qing, il cui regno si concluse nel 1911 con la fondazione della Repubblica di Cina (中华民国). Dopo la sconfitta dell'Impero giapponese (大日本皇国) durante la seconda guerra mondiale, il Paese fu scosso dalla guerra civile, che vedeva contrapposte le forze nazionaliste del Kuomintang (国民党), il partito che allora deteneva il governo del paese, e le forze facenti capo al Partito Comunista Cinese. Nel 1949 la guerra si concluse con la sconfitta del Kuomintang e la conseguente fuga del governo nazionalista sull'isola di Formosa, nella cui capitale Taipei (台北) ha tuttora sede l'attuale Repubblica di Cina, altresì nota come Taiwan. In seguito alla vittoria conseguita sul continente, il 1º ottobre del 1949 a Pechino le forze comuniste guidate da Mao Zedong proclamarono ufficialmente la nascita della Repubblica Popolare Cinese. Dopo l'introduzione di riforme economiche nel 1978, l'economia cinese è diventata quella dalla crescita più rapida al mondo. A partire dal 2013, è la seconda economia più grande al mondo sia come PIL totale nominale sia per parità di potere d'acquisto; per quanto riguarda solamente il PIL nominale, invece, la Cina ha sorpassato il Giappone, sino ad allora seconda potenza mondiale dal 1987, nel 2010. Nel 2022 il prodotto interno lordo cinese è sui ventimila miliardi di dollari.[8] Essa è anche il più grande esportatore e importatore di merci al mondo. La Cina è ufficialmente uno Stato munito di armi nucleari e ha il più grande esercito permanente del mondo, con il secondo più grande bilancio della difesa. È, inoltre, membro dell'ONU dal 1971, quando ha preso il posto della Repubblica di Cina tra i seggi dei membri permanenti del Consiglio di sicurezza delle Nazioni Unite, e quindi gode del potere di veto. La Cina è anche membro di numerose organizzazioni multilaterali,[9] tra cui l'OMC, l'APEC, il BRICS, l'Organizzazione di Shanghai per la cooperazione, il BCIM[10] e il G20. La Cina, unanimemente riconosciuta come grande potenza dal consesso internazionale, è una potenziale superpotenza secondo un certo numero di accademici e analisti che si occupano di questioni militari, politiche ed economiche. Dissidenti politici e gruppi per i diritti umani hanno denunciato la dittatura del governo cinese per diffuse violazioni dei diritti umani, tra cui repressione politica, repressione delle minoranze religiose ed etniche, censura, sorveglianza di massa e la violenza utilizzata nel reprimere il dissenso, come quella esibita durante le proteste di piazza Tienanmen del 1989.

Figure 18-11 represents the amount of energy stored as organic material in each trophic level in an ecosystem. The pyramid shape of the diagram indicates the low percentage of energy transfer from one level to the next. On average, 10 percent of the total energy consumed in one trophic level is incor- porated into the organisms in the next. Why is the percentage of energy transfer so low? One reason is that some of the organisms in a trophic level escape being eaten. They eventually die and become food for decomposers, but the energy contained in their bodies does not pass to a higher trophic level. Even when an organism is eaten, some of the molecules in its body will be in a form that the consumer cannot break down and use. For example, a cougar cannot extract energy from the antlers, hooves, and hair of a deer. Also, the energy used by prey for cellu- lar respiration cannot be used by predators to synthesize new bio- mass. Finally, no transformation or transfer of energy is 100 percent efficient. Every time energy is transformed, such as during the reactions of metabolism, some energy is lost as heat. Limitations of Trophic Levels The low rate of energy transfer between trophic levels explains why ecosystems rarely contain more than a few trophic levels. Because only about 10 percent of the energy available at one trophic level is transferred to the next trophic level, there is not enough energy in the top trophic level to support more levels. Organisms at the lowest trophic level are usually much more abundant than organisms at the highest level. In Africa, for exam- ple, you will see about 1,000 zebras, gazelles, and other herbivores for every lion or leopard you see, and there are far more grasses and shrubs than there are herbivores. Higher trophic levels con- tain less energy, so, they can support fewer individuals.A population is a group of organisms that belong to the same species and live in a particular place at the same time. All of the bass living in a pond during a certain period of time make up a pop- ulation because they are isolated in the pond and do not interact with bass living in other ponds. The boundaries of a population may be imposed by a feature of the environment, such as a lake shore, or they can be arbitrarily chosen to simplify a study of the population. The humans shown in Figure 19-1 are part of the pop- ulation of a city. The properties of populations differ from those of individuals. An individual may be born, it may reproduce, or it may die. A population study focuses on a population as a whole—how many individuals are born, how many die, and so on. Population Size A population’s size is the number of individuals that the population contains. Size is a fundamental and important population property but can be difficult to measure directly. If a population is small and composed of immobile organisms, such as plants, its size can be determined simply by counting individuals. Often, though, individ- uals are too abundant, too widespread, or too mobile to be counted easily, and scientists must estimate the number of individuals in the population. Suppose that a scientist wants to know how many oak trees live in a 10 km2 patch of forest. Instead of searching the entire patch of forest and counting all the oak trees, the scientist could count the trees in a smaller section of the forest, such as a 1 km2 area. The scientist could then use this value to estimate the population of the larger area. SECTION 1 OBJECTIVES ● Describe the main properties that scientists measure when they study populations. ● Compare the three general patterns of population dispersion. ● Identify the measurements used to describe changing populations. ● Compare the three general types of survivorship curves. VOCABULARY population population density dispersion birth rate death rate life expectancy age structure survivorship curve FIGURE 19-1 A population can be widely distributed, as Earth’s human population is, or confined to a small area, as species of fish in a lake are. Copyright © by Holt, Rinehart and Winston. All rights reserved. 382 CHAPTER 19 If the small patch contains 25 oaks, an area 10 times larger would likely contain 10 times as many oak trees. A similar kind of sampling technique might be used to estimate the size of the pop- ulation shown in Figure 19-2. To use this kind of estimate, the sci- entist must assume that the distribution of individuals in the entire population is the same as that in the sampled group. Estimates of population size are based on many such assumptions, so all esti- mates have the potential for error. Population Density Population density measures how crowded a population is. This measurement is always expressed as the number of individuals per unit of area or volume. For example, the population density of humans in the United States is about 30 people per square kilome- ter. Table 19-1 shows the population sizes and densities of humans in several countries in 2003. These estimates are calculated for the total land area. Some areas of a country may be sparsely popu- lated, while other areas are very densely populated. Dispersion A third population property is dispersion (di-SPUHR-zhuhn). Dispersion is the spatial distribution of individuals within the popu- lation. In a clumped distribution, individuals are clustered together. In a uniform distribution, individuals are separated by a fairly con- sistent distance. In a random distribution, each individual’s location is independent of the locations of other individuals in the popula- tion. Figure 19-3 illustrates the three possible patterns of dispersion. Clumped distributions often occur when resources such as food or living space are clumped. Clumped distributions may also occur because of a species’ social behavior, such as when animals gather into herds or flocks. Uniform distributions may result from social behavior in which individuals within the same habitat stay as far away from each other as possible. For example, a bird may locate its nest so as to maximize the distance from the nests of other birds. These migrating wildebeests in East Africa are too numerous and mobile to be counted. Scientists must use sampling methods at several locations to monitor changes in the population size of the animals.

Each gannet chooses a small nesting area on the coast and defends it from other gannets. In this way, each gannet tries to maximize its distance from all of its neighbors, which causes a uniform distribution of individuals. Few populations are truly randomly dispersed. Rather, they show degrees of clumping or uniformity. The dispersion pattern of a population sometimes depends on the scale at which the popu- lation is observed. The gannets shown in Figure 19-3b are uni- formly distributed on a scale of a few meters. However, if the entire island on which the gannets live is observed, the distribution appears clumped because the birds live only near the shore. POPULATION DYNAMICS All populations are dynamic—they change in size and composition over time. To understand these changes, scientists must know more than the population’s size, density, and dispersion. One important measure is the birth rate, the number of births occur- ring in a period of time. In the United States, for example, there are about 4 million births per year. A second important measure is the death rate, or mortality rate, which is the number of deaths in a

KM2 Hoofdstuk 2 GS

Honduras is a Central American nation bordered by Nicaragua, Guatemala, and El Salvador. The Caribbean Sea forms its northern coastline. The Pacific Ocean borders a small southern strip of land. Almanaque Nombre oficial: República de Honduras Área total: 112.090 km2 Población: 9.038.741 Ciudad capital: Tegucigalpa Moneda: lempira Lenguas: español, dialectos amerindios Early History Explorer Christopher Columbus came to Honduras in 1502 on his fourth trip to the New World. As was the case in North America, Honduras, in Central America, had been home to many native indigenous groups including the Sumu and Lenca. Some estimates suggest an indigenous population of up to 2,000,000 before the Europeans arrived. Among these indigenous groups were the Maya. Their civilization spread from the Yucatán area of Mexico to Honduras’ ancient city of Copán. Spain’s conquest of Honduras began in 1525, but it was not easy. It took until 1539 to fully conquer it. There were conflicts with the native population, who were forced into labor. Many died from disease and abuse. Others were enslaved and sent to the Caribbean islands. In addition, there were pirate attacks and in-fighting among the Spaniards. Phawat/Shutterstock Gold and silver deposits were discovered in Honduras in the 1530s, attracting more settlers. By the mid-16th century, mining was an important industry, mainly in the towns of Gracias and Comayagua. More native labor was needed, taking its toll on the dwindling indigenous population. As a solution, enslaved Africans were introduced in the 1540s. This was well before 1619, when enslaved Africans first arrived in Jamestown in the American colonies. The 17th century was filled with conflicts, primarily between the Spanish and the British. Britain wanted to establish colonies on the Caribbean coast of Honduras. They eventually seized the coast with help from the native Sambo and Miskito peoples. However, Spain later regained control. Independence In the early 1800s in Honduras, resentment toward Spain grew. One reason was that Honduras was subject to more taxes to help pay for conflicts that were happening between Spain and France. Other Spanish colonies were also increasingly resentful toward Spain. In 1776 in North America, the 13 colonies banded together to declare their independence from Britain. Similarly, Honduras joined other Central American provinces. Together, they declared independence from Spain on September 15, 1821. Honduras briefly became a part of Mexico, but in 1823, it became independent from Mexico. It then joined the United Provinces of Central America. This included other former Spanish colonies: Costa Rica, El Salvador, Guatemala, and Nicaragua. But the federation did not last, partially due to divisions in political beliefs. In 1838, Honduras declared its independence from the federation. By the early 1900s, the United States had economic interests in Honduras. American fruit corporations like the Standard Fruit Company and United Fruit Company began investing in Honduras to export bananas. To protect American investments, the United States became more involved in Honduras’ political affairs. When Nicaragua appeared to threaten the stability in Honduras, US President Taft sent forces to Honduras to protect American interests. The Great Depression caused economic havoc in the United States and elsewhere. In Honduras, this meant economic problems and political turmoil. During this time, General Tiburcio Carías Andino was elected president, in 1932. He worked to strengthen the military and pay off Honduran debt. Yet he also worked to gather and maintain his own power. He changed the constitution so that he could extend his term in office as president until 1949. His advanced age and pressure from the United States forced him to allow free elections in 1948. General Francisco Morazán In 1823, Honduras joined the United Provinces of Central America. In 1830, Tegucigalpa-born General José Francisco Morazán was elected president of the federation. He remained president until just before the federation disbanded in 1840. aalezk/Shutterstock Morazán favored liberal policies and the reduced power of the church. Morazán was a self-educated man. He recognized the importance of education and the need for schools in Honduras. He believed that girls and boys should have an equal opportunity for education. During his presidency, he tried to make improvements in education. He opened schools that were free to attend. In addition to improving education, he established a system of trial by jury. It was based on the Livingston Code, created in Louisiana. This was a set of reforms to the system of legal punishment. Today, Honduras celebrates the Day of the Honduran Soldier on October 3, Morazán’s birthday. This holiday honors Morazán for his fight for democracy, liberalism, and the nation. Modern Honduras The last half of the 20th century was a political rollercoaster. There were various coups (government takeovers), conflicts, and changing leaders. Starting in 1963, Honduras was primarily led by military governments. This continued for almost 20 years. In 1969, Honduras fought a four-day war with El Salvador. The conflict was over immigration and the shared border. Though the war was brief, the two nations didn’t sign a peace treaty until 1980. With the election of president Roberto Suazo Córdova in 1981, Honduras returned to a civilian government. In the 1980s Honduras was tangled in conflicts of Nicaragua and El Salvador, partly because of the United States. Nicaraguan Contras, who wanted to overthrow the Sandinista government in Nicaragua, were using US-approved bases in Honduras. The United States was also running training camps in Honduras for Salvadoran forces facing their own civil war. This sparked anti-American protests and a desire to reduce the US presence in Honduras. Over the next few decades, Honduras continued to experience political instability. In 2009, President Manuel Zelaya was removed from power by a military coup. People were upset because he called for a referendum to change the constitution. The international community condemned this coup. As a result, Honduras cut diplomatic ties with several countries. In 2010, the United States recognized President Porfirio Lobo Sosa as a democratically elected leader. He was followed by Juan Orlando Hernández in 2014. However, protests in 2015 called for his resignation over claims of campaign fraud. In 2017, Orlando Hernández was re-elected in a disputed election.
