K, but what’s a square foot in metric? And percent would be better here. Or per Mille to be annoying.
replyRead it again, it says right there in square metres.
replyIsn’t it strange to mesure this in surface rather than volume?
replyThe authorities are saying they don't want to see any trash at all, regardless of volume. Imagine 100 sheets of paper vs 100 AA batteries. The batteries have much more volume, but the sheets of paper cover a much larger area so there's much more visible trash.
replyNot much difference between a 12" and a 18" lag bolt for the purpose of "how much trash is visible and impacts terrain".
replySurface feels a bit fairer in that sense. Or at least, easier to measure.
