Reply to comment by stonebraker13 in Podcast: the search for extraterrestrial intelligent life is now looking for "technosignatures" like pollution by asbruckman

It's foolish to believe that any technological civilization doesn't have "pollution". If their home planet has non currently that simply means they moved it into space.

This fantasy that technological civilizations could both have advanced technology and stunning architecture but no byproducts is ridiculous. What did they do WILL steel beams into existence?

I am sure, but I think that for civilizations to expand on an interplanetary level I imagine that they would move beyond self destructiveness that we seem unable, actually I think it's more like unwilling, to leave behind. We are on a path to self-destruction...sadly most mammals will go with us...
