Wasting water in Norway has consequences for the environment Norwegians use almost twice as much water as the Danes. These wasteful habits come at a cost.
Vikings wiped out Iceland’s walruses Walrus tusks were a luxury good, and the ungainly marine mammals probably didn't put up much of a fight when the Vikings came to the island country.
You can combat long-tailed silverfish efficiently and safely, it turns out It’s possible to get rid of silverfish by using bait with small amounts of cockroach poison, according to recent studies from the Norwegian Institute of Public Health.
Trout may be dining on lots of lemmings You see a lemming swimming on the surface of the water. Then it disappears. What happened?
Return of Scandinavian wolves means fewer moose The predator's return to the Norwegian/Swedish border has led to fewer moose in the areas where wolves have their territories. But hunters still kill far more moose than wolves do, researchers say.
Norwegian universities tackle their carbon footprints from travel You would think that universities would be leading the charge to cut back on carbon-intensive air travel. But some members of the Norwegian business community are far ahead of academics in dropping flights.

Humans have always caused plant and animal extinctions Our warming planet is pushing some plant and animals species towards extinction. But there’s actually no such thing as untouched nature — humans have always altered their environment. That doesn’t mean we shouldn’t do our best to protect what’s here now.
Why is so little plastic actually recycled? A group of Danish and Swedish researchers have now tackled this exact question. Their answer? Money.
Norwegians won’t stop flying, even though they know it’s bad for the planet Flying is one of the last things that Norwegians want to give up. Should we require people to cut their air travel by one flight a year? One researcher says that won’t work, and that the only solution is electric airplanes.

Exotic travellers are planet warmers Nature and experienced-based tours to distant countries take us happily out of our daily routines, but they are also far from good for the environment. The tourist industry should really care about how people reach their destinations – not just how many bath towels they are using.
