"And Sarah said unto Abraham: Behold now, the Lord hath restrained me from bearing" (Genesis 16:2, quoted by Thomlinson). But a more scientific approach has been forwarded and it aimed to find solutions. For instance, in the case of couples where the man is sterile, the woman could choose to be artificially inseminated; or in the cases when the woman is sterile, the man could inseminate a surrogate mother. But these alternatives are sometimes frowned upon and seen as equal to adultery (Thomlinson, 1976). All these materialize in increased demands, increased consumption and damaging effects upon the natural environment through increased pollution and reduced resources.
The population dynamics and their environmental effects can also be analyzed from three different angles: size, distribution and composition.
Despite the increasing infertility, the population size continues to increase, directly impacting the surrounding environment. "Population size is inherently linked to the environment as a result of individual resource needs as well as individual contributions to pollution. As a result, population growth yields heightened demands on air, water, and land environments, because they provide necessary resources and act as sinks for environmental pollutants" (Hunter, 2000). As a consequence, efforts have been made to reduce the population size and they basically refer to a reduction in the natality rate. But for a successful impact upon the environment and the natural resources to be felt, additional efforts must be made. These basically refer to a reeducation of the population in regard to their behaviors relative to the nature and could materialize in educational programs as to how to increase the efficiency while reducing the water and energy consumption.
The distribution of population refers to the location of the groups and individuals across space and it has three primary environmental implications: "(1) the increased pressure placed on overextended resources in many less-developed nations as a result of relative increases in population densities, (2) the ecological strain put on coastal resources as a result of amenity-driven migration in the United States, and (3) the ecological effects of ...
Finally, from the standpoint of population composition - or the primary features of a group of individuals (such as age, gender or socio-economic background) - the findings are rather elusive. It has however been found that demands and consumerism, and consequently pollution and eliminated waste, tend to increase as the household income increases (Hunter, 2000).
The features and changes of the current lifestyles have been analyzed from various perspectives and have been found to critically impact the natural environment. The studies have most often been conducted from a political, economic, social or even technological standpoint, and rarely from a demographical one. In this line of thoughts, and due to the numerous forces that a comparison between population dynamics and biological forces would impose, the specialized literature is rather limited on the subject. "Generalizations about the relationship between population and the environment are difficult because of the many types of demographic factors, multiple facets of the environment, and various mediating influences acting on the relationship" (Hunter, 2000)
But even if the results of the conducted studies indicate a somber future, specialized environmentalists argue that the planet and humanity have always found a way to develop and adapt to the new conditions. But even if this is true, it is not certain if the adaptation will be sufficient for the survival of the species. "However, it may be argued that a change of environmental conditions is a major driving force of evolution. The basic question to be answered is: can the rate of environmental change be matched by the rate of evolutionary change? [...] Conclusions can be drawn only from a large number of random experiments" (Richter, Sondgerath, Suhnling and Braune)

Population and Urbanization in Brazil Brazil, officially known as the Federative Republic of Brazil, is located in the eastern side of South America. Without a doubt, Brazil is the largest of the Latin American countries as it covers about half of the South American continent. Argentina, Bolivia, Colombia, Paraguay, Peru Uruguay, and Venezuela are some of its well-known neighboring countries. Its capital is Brasilia while Sao Paulo and Rio de Janeiro
Communities that understand the toll population growth has on the environment are more likely to take action to protect the environment and conserve natural resources by monitoring population growth and encouraging restoration of the environment rather than encouraging larger families (Mulligan, 2006). Community actions are more likely to be tolerated than mandates that declare population growth must be limited by force (Mulligan, 2006). Evaluate Effects of Human Activities on Ecosystems
Chain migration refers to the migration of a population, whereas hierarchical migration refers to the migration of a certain segment of a population. As can be gathered by these factors that influence population growth, community interactions plays a dominate force in population dynamics. The concept of community interactions can be used to encompass such factors as migration, wealth and trade. In other words, each community has specific needs and resources.
Birth Control and Population According to Paul Ehrlich cited in the article "Too Many People," population issues in underdeveloped countries (UDCs) encompass rapid growth rates, birth rates vastly exceeding the death rate because of high percentages of young people, inadequate living standards, and serious problems with high urban concentrations. The consequences include resource depletion, ecosystem destruction, mass starvation, and a further deterioration of living stands. And, although not directly articulated, Ehrlich hits
The demographic tide of Canada is becoming a nagging problem with a dwindling number of active workforce having to bear the increasing burden of quality universal healthcare. However, the problem is that the prospect of a slow growth in the labor market would only imply a slower growth of the general taxpayers and hence raising the tax is not a simple solution to managing the fiscal pressures.

population (or data) you plan to sample for your study. There are a variety of sampling methods from which to choose. Your choice of sampling method will depend on your research design and method. For instance, if you are using a qualitative method you might use purposive or snowball sampling. If you are using a quantitative method, you might use simple random sampling or systematic random sampling. Like research
