One solid reason?
Lack of proper sex education.
A lot of teenagers are curious and already sexually active, but they don’t really understand how pregnancy works, how to protect themselves, or they’re fed myths from friends and social media instead of facts. When curiosity meets misinformation, mistakes happen and pregnancy becomes the result

That was an amazing answer and so true for the time we are in. I am older and am not on social media and didn’t think of that.
