In 1950‚ the populations of the United States and of Latin America were the same‚ at 150 million citizens. Yet forty-five years later‚ Latin America had tripled in population size‚ reaching 450 million eleven years before the United States reached 300 million. This exceptional growth rate was achieved because as Latin America’s infant mortality rate dropped and life expectancy increased‚ their birth rate stayed at the same high rate. This combination repopulated the region at a significant pace and

Critique #3 Lifeboat Ethics: The Case Against "Aid" that Harms By Garrett Hardin After reading the above reading by Mr. Hardin‚ I had come to the conclusion that in life there are many choices that must be made. In correlation to my Environmental Science class I can understand more of what his thought process is. In comparison‚ he could be talking about world hunger.

Since 1991‚ the southern half of Somalia‚ a poverty stricken African nation‚ has seen various tribal militias battle for dominance and power over individual regions of the country. Violence has plagued Mogadishu‚ the capital‚ since warlords ousted the former president.

These factors expressed in the question affect the population density of a country or location immensely. Firstly relief‚ when we talk about the relief we talk about highlands and lowlands.

What we might have been thinking of are the mountainous areas of the world like the Andes

“Filthy Cities” stresses the nightmare that was life for New York’s European immigrants in the late 19th and early 20th century. “New York City was a magnet for European immigrants” (Robins) and this migration from countries such as Ireland was one of the biggest mass migrations in history. The Irish were one of the first groups of immigrants to arrive due to their 1840s potato famine. 1/3 of the immigrants died on the ships on the way to NYC but for those that did arrive safely‚ more struggles and

In my opinion‚ the Easter Islanders used the trees for numerous daily necessities such as building materials for houses‚ to build canoes‚ clothing‚ and logs to move their massive statues.

As their resources declined‚ it brought violence and warfare to the civilization.

The shift from hunting and gathering to more advanced agriculture and food production around ten thousand years ago‚ otherwise known as the Neolithic Revolution‚ resulted in drastic population growth. Though many different explanations have been proposed to explain this growth‚ evidence shows that an increase in the birthrate and fertility of mothers was vital to growth during the transition to an agrarian economy (Larsen 1995: 197). Birth intervals are mainly determined by a mother’s metabolic load

Why do humans have such large brains? Over a span of nearly seven million years‚ the human brain has tripled in size‚ with most of the growth being seen in just the last two million years. Although many explanations for the growth of the human brain have been presented‚ one hypothesis that proves to be most accurate is the Social Brain Hypothesis as presented by Robin I.M. Dunbar. This hypothesis attempts to explain the cause in brain size evolution by attributing it to social relations and social
