7 Billion People

Mme Eyjolfson has been talking about how the world has changed since the time of the voyageurs in the 1800. The world population at that time was 1 billion. In October 2011, the world population reached 7 billion. Today our class watched a National Geographic video which tells a little about how the world has changed: population, where we live, mega cities, technology etc. We also discussed that the life expectancy of a person in 1800 would have been 40-50 years old and today it is 75-80 years old.
