Agree that all things temporary, such as our lives on earth, may seem futile when you look at the big picture, and I have long ago embraced that fact.
Of course, as a society, doing our best to avoid environmental catastrophe and the extinction of humanity, should be of concern to all us now, and especially wrt future generations. I’m sure many of us are involved in those efforts, but, for the purposes of the discussions on this forum, I think it’s helpful to share information wrt real estate, since shelter is, and always has been, a big part of our temporary human experience.
