That's great in a single-variable universe, but in ours unfortunately there are a million other "it's (only) $0.5 per person" things. It's like letting the public choose what students have to learn - "but this is sooo important!" (and this, and this, and this,...). I don't understand that kind of argument. You have to choose the right level of scale for what you are looking at. I would not trust an architect (of buildings) who is a particle physicist, or a forest(-system) manager whose specialization is the cell. Some things need to be looked at the the higher (compound) level to get any useful results. EDIT (for the reply below, to which I cannot reply?): > I find it important / useful for myself to put it into context. Well, my point is that you don't.
