Ask for some anecdotes about Brazil

World ethnographic museum: Brazil is the largest and most populous country in Latin America at present. According to the census in 2000, the population of Brazil is 65.438+700 million. Among them, whites account for 5 1%, mulattoes account for 40%, blacks account for 6%, Indians (yellow race) are less than 1%, and the rest are Indo-European hybrids, mulattoes and Indo-black hybrids. In addition, there are Asians (Japanese, China), and Asians are mixed with whites, blacks and other races. The three major races in the world are all gathered in Brazil, so Brazil is recognized as the country with the most complex race in the world and is called the "World Race Museum". Alcohol-burning cars: Brazil is not self-sufficient in oil, and its dependence on overseas oil is as high as 45%. Therefore, mass production of cars powered by alcohol (alternative energy) is a major feature of Brazil's automobile industry, and Brazil is the only producer of alcohol cars in the world. In the second half of 1980s, alcohol cars accounted for 90% ~ 95% of the domestic auto market, and still account for 30% of new cars. The raw material of alcohol comes from sugarcane. As a big sugarcane producer, Brazil has unique geographical conditions. However, the supply of alcohol is easily affected by the price of sucrose in the international market and becomes unstable. Therefore, the Brazilian government has taken measures to encourage alcohol consumption. First, a large number of alcohol vehicles are produced, and at the same time, gasoline-powered vehicles are required to add 20% ~ 30% alcohol, which greatly reduces gasoline consumption, thus reducing oil imports and saving foreign exchange. At present, the consumption of alcohol in Brazil is greater than that of oil. The healthiest river in the world: Amazon River is the river with the largest water volume and the widest basin area in the world. Its annual runoff is equivalent to115 of all rivers in the world. It has more than 1 1,000 tributaries, with the longest tributary as long as 1 1,600 kilometers. When many tributaries come together, their water volume is equivalent to that of the Mississippi River. The Amazon River is also the widest river in the world. Even from the estuary to 1600 km, its width is 12 km. Its width can reach more than 40 kilometers in rainy season. Where the river enters the sea, its width reaches 320 kilometers. The huge water flow of the Amazon River carries sediment. "Like the sea of Wang Yang, it reaches the horizon and gradually blends with the blue Atlantic Ocean. The vast continental shelf covered by Liu Huang exceeds several European countries. " . The ship went upstream and sailed 3680 kilometers to the port of Iquitos, Peru. Because of its large amount of water and little pollution, the Amazon River can be said to be a river that has not been seriously damaged by human beings so far. 2 1 The investigation report of the World Water Resources Committee in the 20th century pointed out: "At present, only two big rivers in the world can be classified as healthy rivers. The two rivers are the Amazon River in South America and the Congo River in Africa. Because the Amazon River has the largest flow and the widest basin area, there are few coastal residents gathering places and factories. There are no large-scale industrial centers around the Congo River. " The fastest deciduous forest: 60% of the largest tropical rain forest on earth is in Brazil. Because the rainforest is lush, the soil consumes a lot of nutrients, and the soil is so loose that trees have to rely on their natural support-plate roots to stabilize. Millions of years of wind and rain have filtered all the soluble minerals in the surface soil. Without fertile soil, trees "learn" to survive by themselves. The leaves here shed their leaves faster than the temperate trees, and rot faster after landing. In this way, the nutrients in the fallen leaves can be quickly absorbed by the living trees around.
