Day 29- Showing Population Pyramids

Today we watched the YouTube video of Hans Rosling showing two hundred years of history of the world. The video showed a graph of all of the country's in the world put on a graph of income and lifespan. Hans Goslings is a scientist who studies global health. In the beginning of the video The UK and the Netherlands were the best off. After the industrial revolution the European country's and American country's were living longer and making more. At about 1910 the first world war and the Spanish flue brought down the population and income of the world.  World war two affected some country very hard for and some even down below 25 average lifespan. In the time span of 1960s to 2000s most countries started making great gains in both income and lifespan. China was separated at the end to make different areas which range from about Italy to Ghana to show the difference in countries.
