What do you believe are the biggest issues in public health? There are a lot of issues that appear over and over that everyone one knows about (like obesity) but what do you think are some of the most understated important un issues. What are some of the biggest gaps in public awareness ? I'm asking these questions to get an idea of some issues to investigate for a Public Health class. Any response is really helpful so if you've been dying to rant about an issue now is your chance!
