We develop a certain deafness to "old news" and lose our sense of outrage. That's what makes books like this, and museums, and documentaries important. As the last Holocaust survivors and WWII veterans dies, their stories become less vibrant. It is truly unfortunate when that happens before the problems they were addressing or with which they were burdened remain. With Chernobyl and Three Mile Island no longer in the news, and when Flint , Michigan's water problem becomes an old story, the same thing will happen, and the people who weren't around for the story's origin will suffer just like the originial victims.
