With the 2016 Olympics in full swing, there has been plenty of discussion about the environmental pollution at this year's venue - Rio de Janeiro, Brazil. According to a recent Reuters article, for years, Rio has exceeded World Health Organization (WHO) limits for air quality measures, largely due to a high number of vehicles operating within the city. In fact, according to the WHO website, excessive pollution levels caused 3.7 million premature deaths across the globe in 2012.
