    You lost me right at the start. I get the length x width = area. Easy peasy. Now population x per capita consumption are two different attributes which apparently equal “environmental damage” when multiplied. Hmm who says? Where’s the proof? What is “environmental damage”? CO2? Acidification of soil? Of sea? Potholes in the road? What is it measured in and what does it depict? In short that second rectangle isn’t a rectangular relationship at all and is a false assumption. In short that second rectangle is bullsh1t. End of.

    This “rectangles” metaphor is just another repackaging of the per capita fallacy — the mathematical tautology that says, for example, that total GHG emissions = population × per capita emissions, as if this were some kind of brilliant insight. But since per capita emissions are calculated in the first place as total emissions ÷ population, the brilliant insight becomes:

    total emissions = population × total emissions ÷ population

    which simplifies to: total emissions = total emissions!
