i read "Polio survivors, historians, scientists recount battle against virus." by Mark Humbert. it was about the polio epedemic that raged the nation from the 1920's until the dangers climaxed in the early 1950's. in the year 1950 alone almost 33,000 americans were effected by polio, half of them under the age of 10. This relates to the world because it is something that has changed the course of the world. Some of the world greatest thinkers, like Franklin D. Roosevelt and Joeseph Goebbles were effected by polio, and they are people that certainly shaped the way the world is today. This relates to me because if the polio vaccine had never been discovered then me and all other children would have to live in fear and be very careful about polio. This relates to our class because our objective in this class is to change the world, and that is precisely what Dr. Jonas Stalk did in 1954 when he developed the vaccine for polio, this invention rid millions of children who would later be born from the fear of getting polio. I think what Dr. Stalk did can be a model for our class because it shows how much one person can afect the world so drasticly.
