Some ideas for how to deal with the problems of our time seem as naive as pioneer dreams in the westward expansion in the 19th century.
Ideas like --
--hydroponics after the planet gets too hot for plants.
--living in a biodome
--adding sulfur dioxide to the atmosphere constantly
All of these are energy and mineral resource intensive.
These notions remind me of a photo. It was a black and white photo of a rutted trail across the plains. Even though decades had passed after the last pioneer's covered wagon rumbled by, the ruts were a persistent scar on the land.
An upright piano stood at the side of the trail. Superficially, it looked like one could walk over and strike a few keys. Its owners abandoned the piano at a point in the trail where one could see that there were many long miles ahead before a place to water the animals.
I have not been able to find that picture again. If anyone knows it and can tell me I'd appreciate it.
The abandoned piano is an icon for me of a frequent mistake in foreseeing the risks. Too many of us assume that we can take the familiar with us into the unfamiliar, without understanding the fundamentals of logistics.
