Frequently asked questions

Prevention is a powerful form of civic action. Successful prevention requires more than knowledge, it also demands courage, strategy, and relentless advocacy.

The book deals with the prevention of topics such as fire, disease, climate change, and public health drawing upon the stories of researchers like Benjamin Franklin, Ignaz Semmelweis, Sara Josephine Baker or Richard Doll.

It takes effort to confront indifference, ignorance, and inertia to shift society's focus from reaction to prevention. Only by doing so, societies can act early, save lives, and build a healthier, more resilient future.
