Mental illness and suicide have become the greatest threats to school-aged children. Many parents still view dangers to children and teens as primarily physical and external, but they’re missing the real danger: young people spending more time online and less time engaging in real life, free play, and autonomy. While older generations might have learned the value of being outside, household chores, and in-person playtime with friends, the youth of today have fallen prey to smartphones and video games. Childhood 2.0 is an exploration of this dramatic technological and cultural shift, where children and parents face the rise of social networks, mobile devices, and the screen culture, along with addiction, withdrawal, anxiety, depression, online abuse, bullying, the pervasiveness of pornography, sexting, the rise of online pedophilia and sexual predators, the loss of playtime, imagination and autonomy, and the rapid growth of suicide among children and teens. In addition to mental health professionals, the filmmakers speak with a series of concerned parents who have witnessed a profound transformation in their children, especially when placed in contrast to their own beginnings. Then there are the children themselves who speak to the overpowering allure of their devices, the pressures these devices place on them in their daily lives, and the challenge they face when they try to turn away from the screen.
