1. Flying at a whim, large vehicles, a/c 24/7, and related profligate fossil fuel burning. Today we think we're living at the peak of progress so far and that people in any other time would wish they were us.

Future generations will look back at horror at how we chose temporary indulgence over what makes us most human: caring for each other, especially the helpless and vulnerable, and stewarding nature.

2. Plastic, at least single-use, forever chemicals, and similar chemicals. Soon we will see them like asbestos or marketing cigarettes to kids. Yes, they increase the GDP, but they kill.
