In New Jersey, thousands of discarded Christmas trees have dodged the wood chipper and hit the beach instead. They're being used to jump-start new dunes, but scientists warn that these man-made dunes could be less sturdy than dunes that form naturally.
Some dogs need to be on specialized diets for health reasons, but most eat just about anything. That wasn't always the case, however. The domestic dog's ancestor, the wolf, ate only meat. Research suggests for dogs to live with humans, they had to adapt to a starchy diet.
Small amounts of the drugs that people take end up in wastewater and then in streams and rivers. It's usually not enough to harm the health of humans who swim in or drink the water. But there is growing evidence that pharmaceuticals in wastewater may affect wildlife.
Last year a guy in San Francisco jumped on a bicycle, clicked on his GPS, clicked on an app, snapped on his helmet, and 27 miles, 2 1/2 hours and many calories later, he'd etched a valentine message onto a street map of San Francisco. That was nice. Now, a year later, it's getting really interesting.
Most fisheries certified by the MSC system have conditions that spell out how they have to change their operations to comply with MSC standards. But they can still be labeled "certified sustainable seafood" even though they have years to comply.
Industry demand for the "sustainable seafood" label, issued by the Marine Stewardship Council, is increasing.

In the town of Leesburg, Va., a flock of 200 turkey vultures takes over suburban backyards every few years. Despite their seeming abundance, the birds are protected by federal law, so the residents called in backup for some official vulture harassment.
A team of researchers from the British Antarctic Survey stumbled upon some interesting satellite images in 2009: a trail of penguin poop that showed signs of a huge colony of emperor penguins. A team of researchers finally made it out to visit the 9,000-strong colony last December, marking the first human contact the animals had experienced.
