The BBC has a report on generating (souvenir) paper from kangaroo manure. The idea "was inspired by the success of the elephant dung paper industry in Africa." I concede the novelty of the product, but to call it "eco-friendly" needs a little justification. I'd always thought that dung made good fertilizer. Does the benefit of getting a little paper compensate for the loss of the fertilizer? Compare it with growing trees . . .
