The student must 'unlearn' these erroneous 'facts' later, and, just as in erroneous news stories in the mass media, the corrections frequently do no catch up with the errors. As a case in point, chosen from many, the following is from the teacher's notes for the 5th grade text: 'Some students may refer to full, half, and quarter moons. Explain that the full moon is still there but a shadow formed by Earth blocks some of the sunlight reaching the moon.' Many adults have this same misconception, and I suspect that they were so taught in their elementary school. This is an excellent example of the novel and very appropriate concept: the Information Virus. An author's error in a textbook acts like a 'living' virus in that it reproduces itself and spreads by 'infecting' generations of students, some of whom become teachers. A few authors may also spread the virus by copying previous textbooks, thereby perpetuating the error even further."

Well, I guess I am now cool enough to post a reply. I could write a long flame about what is behind this sudden interest in the Amazon, and who is polluting whose air, and who needs to be educated about what, and so on. But this is sci.space, not soc.bigotry talk.propaganda sci.misleading alt.scapegoat or rec.bully, so let me just ask one technical question---in those famous Shuttle pictures, how do you tell smoke from ordinary clouds? ( Now, don't get me wrong---I fully agree that the steady destruction of the Amazon IS a a great disaster, and a great shame for my country. Like most Brazilians, I can't find anything nice to say about our current government. However, it is very hard for us third-worlders to keep these things straight in our minds, when we are bombarded with such incredible arrogance, hypocrisy, and prejudice as displayed in this posting and throughout the recent media campaign to "save the rainforest". Gratuitous exaggerations like "the Amazon area was nothing but smoke" or "60,000 species extinctions per year" only serve to hurt the credibility of the precious few environmentalists among us, to make them look like traitors and instruments of foreign greed, and to make heroes out of those who are doing all the damage. (And indeed, this campaign actually managed to *increase* our president's popularity, which had been scraping the bottom mud for most of his term.) > Apart from the political repercussions, bombing the > Trans-Amazonian highway every fortnight is possibly the most > likely saviour of the forest. Just to be on the safe side, you should also block all the waterways, by dropping a few thousand nukes in the right places. Also, you'd better get rid of all cities, farms and settlements by generously dousing them with napalm. Hunting and fishing of endangered species can be discouraged by poisoning all wildlife with nerve gas. Acid rain (from SO2) and ozone depletion (from CFC's) will provide additional long-term protection. Don't forget to spray Agent Orange over anything that's left of the forest, so that gold diggers can't hide under the foliage. To finish off, you might want to dump a generous dose of CO2 into the atmosphere, which will stop soil erosion by getting rid of the rain... Oh, but of course you will begin your `direct action' at home, right? Like, by bombing the Trans-Alaskan pipeline? And shooting those lumberjacks who are cutting down the Northwest forests? And blasting all those jillions of cars and power plants, which produce far more CO2 than all the forest-burning in the world? > I wish I could put a smiley on that last paragraph, but I can't.

Has space photos of the depleted ozone layer over Antartica stopped the "civilized" population of the planet from recharging their car air conditioners with Freon? How about the styrafoam (sp?) cup you drank your coffee out of? What about the acid rain our factories are causing in other countries (as well as on ourselves)? If we want to stop the destruction in a country which probably suffers from the worse economy on earth we have to do it by giving the Brazilians an economic alternative. In other words, the price will have to come out of all of our pockets if we want to maintain a resource which affects the whole planet. ---- __/\__ ******************** __/\__ | starr@shuxd.att.com \ / * Michael L.

Maybe NASA could ferry the shuttle from Edwards to KSC with camels? Obviously this is a consequence of budgetary constraints, since animals are non-union.

However, NO CRATER nor evidence of any crater exsists. We spell it "Tunguska" in English, and you are confusing the 1908 Tunguska explosion with a multi-meteor arrival in 1947, also in Siberia.

As the social scientists say, "Correlation is not cause and effect." It is difficult to think of anything which would happen *every* time the solar system went through a spiral arm which could cause extinctions on Earth. Contrary to popular belief, the steller density (stars per cubic parsec) in spiral arms is the same as between the arms; it is just that most of the new, hot, and therefore bright stars are in the arms, causing them to stand out. Yes, they have a higher concentration of dust and gas too, but it is more like 1 atom/cc instead of 0.1 atom/cc in the solar neighborhood. Not enough to make a difference. A dense molecular cloud *might* cause enough absorption to make the earth colder for a long period, but such clouds fill a small proportion of the volume of even a spiral arm. -- Stephen Walton, Dept. of Physics & Astronomy, Cal State Univ.
