The vast northern, central and western regions have very small populations, while the eastern coastal areas account for 90% of the population. The southeastern coastal areas in particular are densely populated. The transportation here is convenient, the climate is suitable, the development history is early, and the population is concentrated.

④ Heavy industry is distributed along the southeastern coast, with the main centers being Sao Paulo, Rio de Janeiro, and Belo Horizonte.

⑤Energy: Lack of coal and oil; abundant water energy, 90% of which comes from hydropower. Brazil and Paraguay have built the Itaipu power station.

Learn to correctly handle the relationship between man and land and take the path of sustainable development.

(1) The importance of Amazon rain - global environmental effects

① Regulate the global climate and maintain global ecological balance. The Amazon Basin covers the largest area of ​​tropical rainforest on Earth, 60% of which is in Brazil. The rainforest system is rich in animal and plant resources and plays a vital role in regulating the global climate and maintaining global ecological balance.

②Affect the carbon and oxygen balance on the earth. Rainforests absorb carbon dioxide and release oxygen through photosynthesis, thus profoundly affecting the carbon and oxygen balance on the earth. They are called the "lungs of the earth";

③Regulate global water balance. Rainforests can also absorb and store large amounts of water, promote the global water cycle through evaporation and transpiration, and regulate the global water balance.

④The world’s biological gene treasure house and human medicine treasure house. The rainforest is the world's oldest plant community, rich in diverse species resources, and a treasure trove of biological genes in the world. Human health and happiness are directly dependent on biological diversity. The Rainforest Biogene Bank is an important source of human pharmaceutical raw materials and a treasure trove of medical research.
