Economies of scale
In Competition No. 3171, a challenge suggested by a kind reader, you were invited to submit a requiem in verse for the pangolin. One competitor pointed out that my request for a requiem seemed somewhat premature given that pangolins are still very much with us. Well, for the moment they are. But these shy, solitary, nocturnal creatures (which are more closely related to dogs and bears than to the armadillos they resemble) are being hunted down for their scales and meat and are now critically endangered. What is more, pangolins constitute their own taxonomic order, so if they disappear there’ll be nothing like them left on the planet.
