Great then you're one of the outliers doing much more than the average person. We can try a few more (drive a car? buy goods in plastic bags or containers? eat meat?) but that's not really the point.

My point is that Grandma was just following societal norms in her day. She wasn't aware to the level we are now. And most people today, young and old, despite being much more aware, still live horribly unsustainably day to day.

Constantly painting this picture or the poor, angelic millennial being horribly mistreated by their grandparents might make you feel better but it doesn't help anyone. It's just more stupid, ignorant adversarialism.
