We could have a very long answer, but I think the short answer is that we do take it seriously. We've lost a couple of decades. It isn't that it necessarily needs whacks of money, but it does need thinking through: how we invest, how we make decisions, what we do, and things that support kids to be active, things that support healthier choices as being the easier choices in schools, etc. So it's all levels of the system actually thinking about what's connected to what.
And if you ask kids—there's a recent survey that came out—what they do after school and what they want to do after school, they actually want to be a lot more active, but they don't have an easy, safe place to do it, as a for-instance. And if you're in a neighbourhood that has green space, you're healthier than those who don't have green space--period, end of story.
So it's how we design our communities, how we make our investments. Do we have easy, safe places for people to walk or ride their bike? When you go into the school, is chips and gravy cheaper than an apple?
I'll leave it at that, because there are all kinds of little things. We need to see the connections.
