Food, Population and Environmental Problems Brazil Essay

It is a fairly universal strategy to examine past and present trends in order to forecast the future. This can be commonly observed in everyday existence, as people rely on previous climate trends and recent weather phenomenon in order to make decisions such as how to dress and mode of transportation to use to go to work. Likewise, by employing the use of past and present data and trends, policymakers can make predictions of the future in order to create more effective policies, as well as find better â€Å"prescriptions† to solve existing problems (Lecture, 4/1/2010). There are existing neo-Malthusian theories, such as those made by Donella Meadows, et al., that the current trends, including increased population growth, subsequently†¦show more content†¦The examination of the population growth of Brazil can reveal much about the choices of its residents, and the forces determining these actions. It is important to note that throughout the last fifty years, Brazi l’s population has grown significantly, from 71 million in 1960, to 170 million in 2000. It subsequently became the world’s fifth most populated country (Smith, 229). Although the aggregate growth is obvious, the rate of population growth itself has slowed considerably, evident from observing the country’s rate of natural increase. Holding migration constant, rate of natural increase has steadily decreased from a peak in the late 1950’s and early 1960’s. During this period of deceleration, crude birth rates have decreased rapidly, while crude death rates have also declined at a slower rate (Fig. 1). The overarching trend for net migration since the 1980’s is that people have been emigrating out of the country at an increasingly faster rate, also leading to a decline in the population. These trends can be explained by a multitude of different factors, both social and economic. A major explanation for the sharp decline in Brazil’s crude birth rates is its evolution into an industrialized nation. This corresponds with the changes in the rate of natural increase described above, as it burgeoned in the mid to late 1950’s through its government’s use of industrialization through import substitution.Show MoreRelatedGenetically Modified Organisms, Or Gmo?1668 Words   |  7 Pagesthe World). In recent years, the genetic modification of raw food products has risen as a new alternative to traditional breeding since it provides faster results, is more efficient, and is more precise in targeting specific traits. â€Å"There are some problems that conventional methods can not solve† says Francisco Aragao, who is a researcher at EMBRAPA.

Currently, the global population is 7 billion, and the increase rate is 1.3% annually that means by the end of the twenty-first century the population will reach twelve billion (Keenan, 2013). Therefore, there is a huge debate going on right now regarding overpopulation. For some people, explosion in population has no detrimental impacts in the future, and it will be bearable. In contrast, others believe rapid growing population can cause disaster; this concept is the mostRead MorePromoting Environmental Stability For Poverty Reduction And Sustainable Development Essay1677 Words   |  7 PagesTopic 1: Promoting Environmental Stability for Poverty Reduction and sustainable Development Introduction In UNEP’s Global Trends in Renewable Energy Investment in 2016 report, they discovered that the developing world’s investment in renewable energy now accounts for more than 50% of all investments in renewable energies .

It is widely known that fossil fuels are non-renewable resources and the use of fossil fuels harm the environment, such as the combustion process of fossil fuels that leads to global warming. However, current societies are still dependent on fossil fuels. Because of the environmental problems and in order to decrease the wide-ranging consumption of fossil fuels, researchesRead MoreCompetition for I ncreasingly Scarce Resources in the 21st Century1214 Words   |  5 Pagessolution to these problems. Unfortunately, even though innovations in agricultural practices have increased yields even further than during the second half of the 20th century, most authorities agree that realistic limits are already being reached.

The Amazon River and rainforest are located in Brazil, a country with more than 800,000 square miles of coastline, and a landmass so large that its borders touch all but two of its neighboring countries (Rich, 1999). The Amazon rainforest is the worlds largest tropical rainforest, and for purposes of comparison, its size is equivalent to one-half of the entire United States (Rich
