Every child's path to adulthood-reaching developmental and emotional milestones, learning healthy social skills, and dealing with problems-is different and difficult. Many face added challenges along the way, often beyond their control. There's no map, and the road is never straight.But the challenges today's generation of young people face are unprecedented and uniquely hard to navigate. And the effect these challenges have had on their mental health is devastating.Recent national surveys of young people have shown alarming increases in the prevalence of certain mental health challengesin 2019, one in three high school students and half of female students reported persistent feelings of sadness or hopelessness, an overall increase of 40% from 2009. We know that mental health is shaped by many factors, from our genes and brain chemistry to our relationships with family and friends, neighborhood conditions, and larger social forces and policies. We also know that, too often, young people are bombarded with messages through the media and popular culture that erode their sense of self-worth-telling them they are not good looking enough, popular enough, smart enough, or rich enough. That comes as progress on legitimate, and distressing, issues like climate change, income inequality, racial injustice, the opioid epidemic, and gun violence feels too slow.And while technology platforms have improved our lives in important ways, increasing our ability to build new communities, deliver resources, and access information, we know that, for many people, they can also have adverse effects. When not deployed responsibly and safely, these tools can pit us against each other, reinforce negative behaviors like bullying and exclusion, and undermine the safe and supportive environments young people need and deserve.
