Well think about it in this light, MDG. We need McDonalds to control the world population. Otherwise, if everyone ate only "healthy" food, they would live longer, and the world would become overpopulated.
Since the above were concerns that you and Kevin Dempesey brought up in "Anything Else", you should congratulate McD's AND the tobacco industry for the excellant job they are doing on controlling the population.
With so many people dropping dead from heart attacks, cancer, and strokes (or maybe inhaling too much methane from farting cows) way before they turn 70, we don't have to worry about Mother Earth becoming overcrowded.
But seriously, as I've said before, parents need to take the responsibility, and teach their children good eating habbits, and moderation when it comes to "junk food" and fast food. Yes, the ad man is gonna be doing his thing. Parents of small children need to do their thing also.
