Michael Moore does a good job of pointing out how the media tries to scare us in his movies.

Humans in North America are enjoying an increased life span and better quality of life.
There are plenty of good news stories if you look for them. As JW's we are used to only seeing the bad ones, and the media is quite happy to help that notion along. In fact, government benefits from keeping citizens in fear (again I refer to Michael Moore).
Look at the amazing advancements in medicine, science, technology. I read today about a paralyzed man who can now communicate via his brain waves. I'm no longer afraid of the future, I'm excited, and eagerly awaiting the many new things we have yet to learn and experience.
