I worked many years in the environmental field.
I still do some consulting work via @kocakwords in that area.
If we have wastewater, can we also have wastetime? May we? Where does time go when it is wasted? Or is it metaphysically and physically impossible to waste time? Are their emissions related to wastetime? Are they harmful or beneficial? How are they measured? Do we even want to measure them?
What about space? If there is wastewater, is there wastespace? Is that what people mean when they angrily assert, "You're fired! You're just wasting space around here!"
Or is it, again, impossible to "waste space"? And if you can waste space, what are the impacts? Can they be mitigated? May they?
