Actually I did not say that, I was quoting from the Martyn J. Fogg article, though that question on the plants was mine.

As for Carl Sagan, while I think he was a better scientist than you rate him to be, I think what mattered more is the work he did making science and the Universe accessible to the public. After all, where are future scientists going to come from, and what I see of the ignorance of your average person when it comes to science here in the start of the 21st Century only makes me appreciate any such efforts to wake them up even more.

Actually, could you tell me what some of the many things Sagan said were "bogus"? And Nick may know more about Mars than Sagan, but he also has a decade's more worth of new knowledge on the planet than Sagan, who is no longer around to collect such info or defend himself.
