Global environmental challenges
Many people hope to come back from a wildlife safari with close-up pictures of lions or elephants – this picture below is my best attempt from a search for the largest land animals in Antarctica.
If you look hard you can see a reddish blob at the tip of the thumb — it’s Antarctica’s most aggressive land predator, an eight-legged mite known as Rhagidia.
Pete Convey, a biologist at the British Antarctic Survey (that’s his thumb), says that such tiny creatures evolved in Antarctica over tens of millions of years — they can freeze their bodies in winter in an extreme form of hibernation.
Penguins, seals and whales are the best known animals in Antarctica, but none live year-round on land, where the biggest creature is a flightless midge whose name is ”Belgica antarctica” and who’s about 0.5 cm long.
There are plenty of ways to get around New York City, not all of them savory — subway, bus, car, taxi, bike, shoe-leather — but few offer the environmental cachet of the plug-in electric motorbike. Sleek, slim and silent, the Vectrix two-seater owned by filmmaker Michael Bergmann is definitely preferable to rocketing around town under almost any other kind of power. The ride from the East Side to the West Side one recent evening was an absolute pleasure, with less ambient noise than a golf cart as we zoomed across Central Park.
“I’ve always felt that enjoying life in New York to the fullest requires a way to get around New York,” Bergmann said later in an e-mail. “A way that’s quiet and up on the surface so you can enjoy the varied life and changing neighborhoods as you travel. That requires a vehicle that’s street legal (so I don’t worry about being stopped or having it confiscated), always available, that isn’t hard to park, that doesn’t contribute to congestion or pollution (air or noise), that can carry the amount of stuff one ordinarily carries, and carry a passenger as well. So as soon as I found out about the Vectrix I wanted one.”
