Having said that, merely hoping that people will make significant changes in their lifestyle for indirect and abstract benefits is simply burying one’s head in the sand with a rationalization that makes them feel good. The population is growing, and we will either innovate our way out of this, or it’s famine/war/etc.

I don't think that really works any more than the "look I'm killing the cows" argument. If they have to throw away packages each week, they'll buy less in the future, which in turn leads to lower production.
