New Unit!

Today we started a new unit following a slide presentation. The slide presentation that we took notes on was based on an A/P Human Geography textbook, so we only had to take some notes. The new chapter was called 'The Cultural Landscape'. The key issues of this topic were; where is the world's population distributed? Why is Global population increasing? Why does population growth may very among regions? And finally, why do some regions face health threats? For the topic "where is the world's population distributed"? The population concentrations of that are; 2/3 of the world's inhabitants are clustered in the following four regions: East Asia, South Asia, Southeast Asia, and Europe. There are also site and situation of population clusters, low-lying areas with fertile soil and temperture climate, and also near an ocean or near a river with easy access. The second part or slide of that section is based on humans avoiding clustering in certain physical environments, such as dry lands, wet lands, cold lands, and high lands. Places that are considered too "harsh" for occupancy that have diminished over time. The next section was 'Population Density'. Density can be compared in up to three ways for a place. Number one, Arithmatic Density, with a computation that divides the population by the land area. Number two, Physiological Density, which is the number of people supported by a unit area of farmable land. The computation divides the population by the arable land area. Finally, there is Agricultural Density, which is the ratio of the number of farmers to amount of arable land. The computation for that divides the population of farmers by the arable land area. The last section of the unit that we covered today is, "why is global popualtion increasing"? This is because there is a Crude Birth Rate also known as a (CBR)- the total number of live births in a year for every 1,000 people alive in society. The second reason is because there is a Crude Death Rate also known as a (CDR)- the total number of deaths in a year for every 1,000 people alive in society. These topics are components of population growth. This is all we covered today in class.
