Nudnik - n. U.S. colloq. Esp. in Jewish usage: a pestering, nagging, or irritating person
What we do know for certain is that the krill's chances of survival are a lot greater than, say, the Italians, or the Germans, or the Japanese, Russians, Greeks and Spaniards, all of whom will be in steep population decline long before the Antarctic krill. By 2025, one in every three Japanese will be over 65, and that statistic depends on the two out of three who aren't over 65 sticking around to pay the tax bills required to support the biggest geriatric population in history.
Does the impending extinction of the Japanese and Russians not distress anyone? How about the Italians? They gave us the Sistine Chapel, the Mona Lisa, Gina Lollobrigida, linguine, tagliatelle, fusilli . . . If you're in your scuba suit down on the ice shelf dining with the krill and you say you'd like your algae al dente in a carbonara sauce, they'll give you a blank look. Billions of years on Earth and all they've got is the same set menu they started out with. But try and rouse the progressive mind to a "Save the Italians" campaign and you'll get nowhere. Luigi isn't as important as algae, even though he too is a victim of profound environmental changes: globally warmed by Euro-welfare, he no longer feels the need to breed.
