Things are not getting worse. In fact, they are getting better. That is not to say there aren't issues of concern that need to be addressed.
What has changed if that technology and culture have made it possible to be aware of all the things that are going on around the world almost instantaneously. As another poster replied, there have been more catastrophic events in mankind's history than what goes on now. Thanks to social media and 24 hour cable news networks who use the business model "red makes green" we are given an unhealthy diet of issues that are serious, but do not personally effect us or the area we live in. The result is a sense of "end of times," that just isn't true.
