Population Pyramids continued

Today was an easier day than what we had been doing the past few days. Mr. Schick continued with the presentation on population pyramids. The main focus of this class was different types of shapes of population pyramids. There are three basic shapes of population pyramids. They are the Christmas tree, the box, and the cup. Knowing this information, the first population pyramid we looked at was that of the United States of America. We all concluded that the United States' population pyramid was a box, meaning that all age categories are about the same in percentage, male and female. The Christmas tree is most commonly found in pyramids of developing nations. The growth rates are slow and the birth rates are high. These populations also have short life expectancy. Examples of these countries Namibia and Bangladesh. The box represents developing nations or slow growth. They have low infant mortality rate and slow population growth. The people in this population have long life expectancy. Examples of such populations include Sweden and the USA.

Then the Carthaginian empire strikes back. The second Punic War was fought from 218 to 201 BC. The twenty nine year old Carthaginian general known by the name of Hannibal almost does the impossible and defeats Rome with a well thought out strategy. There is a good reason of why this war was the longes
