This string was inspired by Fr. Franklin's topic from a year ago, "AI will kill us all." In this string, I am saying the GND will also kill us all. Here's why:
In a movie from 2019, "Io" [as in Jupiter's volatile moon]
"In a post-apocalyptic time, the earth has been rendered toxic, and most of humanity has abandoned the planet and colonised one of Jupiter's moons, IO. But young scientist Sam Walden has stayed behind and dedicated herself to finding a way for human beings to survive on Earth." [from a film critic https://www.imdb.com/title/tt3256226/
Another critic said, "The amount of the stuff happens in this movie is perfect for a short film. Unfortunately it is now just 90 minutes of boredom."
What I found fascinating is that in the first two minutes of an obvious morality tail about the sins of environmental destruction, which only the GND will solve, Sam, our intrepid female scientist, gathers water from a puddle in the street on toxic Earth to test it. The test doesn't matter because Sam, in an absent moment not edited out of the morality tale that should have been on the cutting room floor, tossing the wrapper of the glass vial... in a recycling bin? God, no! on the street, of course!
When we actually do land on Mars to colonize it, we will discover, to our shame, an ancient, long-since decimated intelligent culture. We will find record of the sad story of their effort to revive a dying civilization due to something they called "climate change," and had something similar to the GND. They succeeded in eliminating all emissions, reaching a net-zero condition by eliminating all sources of methane emission: all living things. Congratulations. life finds a way, even if it must come from Earth, and all our recycling.
