The Effects of Population Growth in Brazil
The population of the world today is 6,112,911,145 and progressively growing. Unfortunately, that figure is expected to double by the year 2050. Four-fifths of this population resides in developing countries of the "South". Because of extreme levels of fertility, mortality, and new migration, these developing countries are accountable for most of the world population growth. There are many reasons that explain why the numbers are increasing, but the main reason is the way of life for many of the people inhabiting these regions. With the combination of an unmet demand for family planning and the desire for a large family, the world's Total Fertility Rate(TFI) is 3.1. This is significantly higher than the average population replacement TFI of 2.1.
The population explosion is forcing people to migrate away from the city and into the surrounding area, which is causing an urbanization of the rural areas. To support this spreading, roads and cities are being constructed where plant and animal rich ecosystems exist. One region of particular global concern is the Amazon Rainforest and the effect of the spreading population from the coastal areas of Brazil. Currently, Brazil has a population of 172,860,370 people. A majority of this population currently depends on the local rainforest to support human growth. It has been reported that at current deforestation rates, only scattered remnants of tropical rainforests will exits and a quarter of a the species on Earth will be extinct by the time today's preschoolers retire. However, because of the ever-growing need for development, the soil, the trees, and the wildlife of the Amazon Rainforest are suffering at the hands of a demanding population growth.
Soil Condition and Agriculture, Politics and Industry
Agriculture is a big factor in the rainforest region of Brazil, which is the fifth biggest country in the world and home of 140 million people. It allows one third of its population (the ca. 400 native tribes, the poor and the migrating people) to support themselves, their families, and the rest of the nation. While the coastal regions, which contain two thirds of Brazil's population, are in dire need of food products and depend on the local agriculture, Brazil's production of coffee, sugarcane, cassava, bananas, and sisal is number one in the world. In the Western Hemisphere, it is the leading producer of rice and pulses (beans, peas, and lentils). It ranks second in the world with the production of oranges, cocoa, and soybeans, and third in the production of black pepper, and corn (maize) and in the size of its herds of cattle and hogs. With the help of more intensive farming technology (like the use of fertilizer, use of hoes for weeding, or planting of crops in rows rather than scattering seeds), the amount of land that poor people need to reclaim from forests to feed themselves could be reduced by high numbers.
