I agree that we're not that active anymore but the statement, in my opinion, is untrue because we still spend most of our free time being active and not on our phones.
It's very important for young people to be active as some activities that need you to be active increase height, decrease weight and help you with other things in life.
Again, in my opinion it's the child's parents to ensure that their child/children are being active enough.
