Population dynamics

1. Abstract

The world we live in is marked by constant change and th***** affects all features of every day life. Among *****e most relevant ********** that affect the contemporaneous society, one could easily point out the larger number ***** possibilities and therefore the increasing demands and consumerism levels. To better explain, ***** business community has changed its focus from producing and then selling, to prospecting the market in order to only produce those items that will sell without much effort. In other words, as they are given more options ***** as the manufacturers are there to serve their needs, the populations increase their ***** and consume more than ever. All these then reflect upon the environment, which suffers ***** excessive extractions. And the environment is a constant and necessity of our *****s. ***** this particular context, the need to analyze the population ***** from an environmentalist perspective arises.

*****. Population Dynamics

The dynamics of population refer ***** ***** numbers and characteristics of certain groups of all mankind, animals and plants that need to function *****gether as a whole ***** sustain each other. The ***** ***** have been studied for years from numerous standpoints, including political, economic, mathematical and even medical. A new door opens when the matter becomes analyzed ***** a biologic*****l angle. "Population is the number ***** individuals of a ***** species in an area. Animal *****d plant populations depend on many things for survival. Limiting factors like the vailability of food, water and shelter can impact an organ*****m's population. In nature, *****s of animals and plants are linked together ***** a puzzle. The pieces of the pl*****nt ***** animal puzzle depend on each other to *****m a complete picture. If something is wrong with ********** ***** the pieces, it *****s the whole puzzle" (New Hampshire Public Television, 2008)

The population dynamics for ***** ***** global commun*****y ***** be summarized as follows:

*****tal of 6,677,563,921 people are currently inhabiting the earth

27 percent are aged between 0 and 14; 65 percent ***** aged between 15 and 64; 8 percent are older than ***** the median age is ***** 27.4 years for men and 28.7 for women in 2008, ***** population registered a growth of 1.159 percent birth rates: 19.97 / 1,000 population death *****: 8.32 / 1,000 population life expectancy at birth: 66,12 years - 64.18 ***** for male and 68.2 for female total fertility rate: 2.58 children born per woman literacy: 82 ***** - 87 percent ***** male and 77 percent for female (Central Intelligence Agency, 2008)

Along the recent decades, s*****al environmental changes have been felt and *****y begin to ***** and more impact the population dynamics. A first such change is ***** by the increasing global warming, ***** is likely ***** gene***** an increased temperature. "*****ll model stimulations show a warming in the future [...] The frequency of winters classified as cold will decrease, whereas hot summers will become much more frequent" (Richter, Sondgerath, Suhnling ***** Braune). As a result of ***** ch*****nges,
