Hans Rosling 200 years in four minuits

Today in honors human geo we watched a video by Hans Rosling that showed the difference between the nations of the world in both their life expectancy, and their GDP per capita over the last 200 hundred years.  This video was about 10 years old so it started in 1810.  At this time all of the countries were in the poor and sick corner of the graph  with a life expectancy of at max 40.  at this point all of the countries were near the same with some deviation, and England with the Netherlands only slightly ahead economically and with life expectancy.  Then after that the Industrial revolution began to spread to the rest of the western world.  this caused a large amount of European nations and America.  This rate of growth continued until the early 20th century then at this point the Spanish flu and WWI hit.  both of these things claimed massive amounts of casualties.  then the countries started to rebuild, and even through the great depression the countries continued to grow.  then once WWII began many countries like Japan and Russia suffered miserably.  Then by 1948 the greatest deviation between the richest country, and the poorest country showed.  As time went on many of the Asian countries that hold large amounts of power began to grow in economic strength.  today the countries are getting closer together, and with new things such as green energy it is suspected that other nations can start to move to the rich and healthy corner of the graph.
