Today for class we talked about population. There are +7.6 billion people on Earth. The population increases by 73 million/yr, 8377/hr, 149/min and 2.5/sec. 90% of population growth takes place in developing countries in Africa, South/East Asia and Latin America. Crude birth rate is the number of births per 1,000 of the population. Crude death rate is the number of deaths per 1,000 of the population. The Rate of Natural Increase is produced by subtracting the death rate from the birth rate. This gives us the annual natural growth rate in percentage form- for a country or region. Net migration Rate is the difference between the number of persons entering and leaving a country during a year. An excess of persons entering a country is net immigration. For example: Canada has 5.65 migrants per 1000 population. An excess of persons leaving a country is net emigration.

He's a Biologists which is the study of human physiology. His real passion is to study birds. The book explains why Eurasian and North African civilizations have survived and conquered other areas. One factor of this is Geographic luck. This is when you are born into a well-developed area that is better than other areas. The book is also showing why white supremacy is wrong.
