How we die (in one chart)...
This infographic shows the main causes of death in 1900 in the United States and compares that with the 2010 figures. The United States, during that time underwent what many call the epidemiological transition (in essence, in developed societies we now die for different reason and generally live longer) What are the geographic factors that influence these shifts in the mortality rates? What is better about society? Has anything worsened? How come? Via Seth Dixon, Fortunato Navarro Sanz, Marc Crawford , Mankato East High School

Of course medicine has changed a great amount in over a century, but the fact that they were concerned with cannon balls back then? Were there that many pirates, and circus acts?

In the 1900s, there were more "natural" caused illnesses but not enough medicine or technology to alleviate these diseases, hence, the greater mortality rate. Presently, medicine and technology has changed for the greater good. Many of the diseases are cured and more people living longer due to this. However, mortality caused by heart disease and cancer have increased in 2010; this is probably due to higher calorie diets and exposure to preservatives and radiation.

Looking back and comparing the 1900’s to 2010, I think it is becoming quite evident that our surrounding environment and what we consume impacts our health. Honestly what kind of cancer are you not at risk of getting today? Factors can vary from the genetically altered food we consume, radiation emitted from our cell phones or even prolonged exposure to the sun. While combating harmful pathogens and bacteria may have been a critical health concern and challenge of the early 20th century, finding remedies to an increasingly toxic environment may characterize the medical needs of the 21st century.
