In a few very publicized cases, the government is trying to get directly involved in maintaining (or improving) the health of America's children by putting weight on report cards, removing vending machines from schools, etc. Is it important to do such things, or is it a lost cause? If so, why, and what causes the problem in the first place (like marketing of junk food directly to children)? And is there something, ultimately, that could reduce the incentive for children (and people in general) to eat junk food, or is the approach that these schools are taking (by removing the temptation entirely) the best (or is it an impossible problem to fix at all)?
