Sad, indeed. And they are really beginning to push this carp in the schools, showing Algore's environmental scarefest. I can imagine some weak minded kids being pushed over the edge to suicide or homicide because they have been led to believe that the earth is dying and they have nothing to live for.
Being from a progressive school district, and near the end of the baby boom, I can tell you they started back then. We were shown a lot of stuff, woven into both english class (through sci-fi lit), science and social studies about how by 2000 there wouldn't be any good air to breath - anyone left would be wearing gas masks to survive. We were shown Future Shock about every year in Jr High. Rachel Carson was quoted as nearly a messiah. We were the test subjects - getting every flaky new education idea coming out of the University College of Education. During the X-er years they were deploying it across the country.
My kids though, in the same progressive school system and getting all the same kind of agenda driven stuff are part of a generation that is savvy to spin. They and their classmates really didn't take any of the indoctrination seriously - they saw it as part of the game you play to make it through the system without getting in trouble. I think that's one of the reason the educators keep raising the volume - it's having less and less impact over time. I remember hearing about kids 50 years ago not understanding that the point of commercials is to part you from your money - today kids not only see the point of commercials, they talk among themselves about the strategy behind it! Between the increasing savvy of the kids, the proportion of kids in conservative homes, and the move toward more family centered education, I'm not too worried about the future. They don't buy everything they see or hear, and if they wonder about something they hear the resources are at their fingertips to find out more, and that gets them all sides. That's why 'Google" has become a verb as well as a noun ;-)
