Yeah I don’t think it’s government’s problem to solve, but it is a significant problem.
How anybody could deny it is beyond me.
When I was in grade school, the only school buses were in rural areas where the trip was many miles. Everybody else walked. Now (at least here in Indiana) nearly everybody rides. I think it gets kids off to a bad start activity wise.
More activity would help, but I think the best solution is through proper nutrition. I like the Jack Lalanne method of nutrition, “If God made it, eat it. If man made it, don’t”.
