The “we gonna die” lobby hasn’t had much luck in scaring more than a few people. .Let’s see. What scares have we had in the past that didn’t pan out because they were the product of insistence, rather than science:.The comet scares of the early 1900s. HS gas detected by spectra in the tails caused GW/CC type “scientists” back then to screech about toxic gas..The “theory” of eugenics of the first half of the 1900s, i.e. the idea that low intelligence would become universal..The world blowing up from nukes in the 1960s and 1970s and 1980s. Several problems with that idea. Didn’t stop the dummies from pushing it, though..A new global ice age in the 1970s..EMP.Nuclear Winter (Chuckie Sagan.).Running out of Helium. Despite an abundance both in the ground and in the atmosphere..Ozone holes despite a near vacuum being incapable of stopping anything..Ocean acidification..GW/CC.Run out of food by the mid 1970s..Run out of water by the 1990s..Run out of oil by 1970. Umm, 1980. Umm, 1990. Umm, 2000. umm….Run out of metals by the 1980s..The current scare by ecos about metals that are background levels from natural sources in the 1ppb and less concentrations..A common problem with ALL of these ideas is that they were pushed by activists who ignored most of what was known. ALL of them were also pushed by someone with an ulterior motive. NONE of them were in the public interest and the typical reason for pushing them was money, not science, be it grants or creating new industries based on junk science.
