Wonderful to see such an old presentation by Margulis. I read about it in 1990, book "Gaia, The Growth of an Idea" by Lawrence Joseph. What got me thinking recently was that we might finally send humans to Mars, and then it occurred to me that perhaps something of what life is might be a collective, and if we send ourselves or other life far from the earth, we and it might not function as we're used to on earth. We've never left low earth orbit for more than a week or so to the moon, and never further. What would it mean if we discovered seeds didn't germinate on Mars, even if all the chemistry, temperature and light was present? Maybe unlikely, but we can't really know until we try. If life had problems away from the earth, we might conclude earth is not a "planet", but a "Gaia" and life or complex life only exists on Gaias, and we'd need to investigate what's missing elsewhere, or whether it is something we can carry with us, or if a sheer scale of life itself is needed. And the Lovelock would be right - that life only thrives at the scale of a planet.

Two misspellings in the title cards does not give me confidence.

Well, the good thing is that it's irrelevant what your confidence level is. This is essentially now called Earth Systems Science, and entire multidisciplinary academic field. 🤷 It's for the most part now part of consensus peer reviewed science.
