Not being able to easily quantify the inefficiency of one kind of waste is a very simple reason to not be mad about it. And, of course, one can express a desire to want to fix one problem without being obligated to express the desire to fix problems many orders of magnitude larger ("You don't want our town to cut down the trees in the park? Why don't you care about the destruction of the rainforests?"). You don't even know that the person you're talking to doesn't want to fix those problems.
