There are so many ridiculous questions about global warming on Yahoo Answers that I've believe that the fossil-fuel industry is sponsoring them.
This would be similar to the ads for cigarettes that were slipped into movies, where each photo of someone smoking would get a flat payment of a few hundred dollars. (See http://www.mascotcoalition.org/education/movies/lancet.html).
So: do you believe these that the Environment section, in particular, is being saturated by paid advertisers?
