Roel de Boer is a Dutch product designer with a fondness for playing with ideas about sustainability. He dreamed up these tree houses that look like alien nests and a wood stove that burns individual spruce trunks. Inhabitat dug up another one of his ideas: roofing tiles that will turn the steep sloped roofs of old buildings into fancy new green roofs.

Here's what they'd look like in action, theoretically:

Pack up your kids and move to Queens. One public school there, Public School 244, has become the first in the city, possibly the country, to go vegetarian.

And the food sounds pretty darn good. Here's a sample of offerings, via the New York Daily News:

BREAKFAST MENU
Whole-grain sunrise carrot bread with hot cereal choice
Fluffy egg omelet with melted cheese in a New York-style bagel
Waffles with warm syrup and
mozzarella string cheese

LUNCH MENU
Black bean and cheddar quesadilla served with salsa, red roasted
potatoes and broccoli
Roasted organic tofu with cacciatore sauce, whole-grain pasta and roasted zucchini
“Superhero” spinach wrap with cucumber salad
Chickpea falafel in a soft wheat wrap with chopped romaine, fresh diced tomatoes and cucumber salad

This is pretty staggering. Why haven't the sharks made a classic movie about a terrifying rampaging human? "We're gonna need a bigger ocean."

Wait, there's more.

Naki'o is a mixed-breed dog from Nebraska who got frostbite in a cellar when he was a puppy and lost his limbs and part of his tail. But now, thanks to a United States company called Orthopets, Naki'o has been fitted with four prosthetic legs. Now, he can do all the things dogs like to do. He can run. He can play. He can be a wonderful dog like he always was, but now, he can enjoy it more.

Nutria are 20-pound rodents that are gnawing away at the coast of Louisiana. They are eating so much vegetation, principally roots that hold fragile outlying coastal pieces of land together -- kind of the way eggs bind a cake -- that they are causing serious problems. Like, "See ya, Louisiana Coast!" type problems. The sad thing is that someone actually deliberately brought the big fat rat thingies into Louisiana from Argentina in 1930 because they had the brilliant idea they were going to make fur coats out of them. And now, there are way way way too many of these things to make fur coats. I mean, even if everyone in the world was Paris Hilton and wanted a fur coat, they'd have leftovers.

So, what do we do about nutria? Time to start eating! At least, that's the most recent plan put forward by the Louisiana Department of Wildlife and Fisheries -- reduce nutria populations by turning them into jambalaya and snack sticks. Some dudes who are making a film about nutria, entitled Rodents of Unusual Size, wondered what all this culinary innovation tasted like. You can watch the taste test here. Or just run.

The first thing you will probably notice in this photo is the awesome ad campaign on the back of the bus. We're totally into this. Every lane is a bike lane! Big metal vehicles should share the road with bikes!

Now look down.

Oh, that's a bike lane, huh?

Hm.

Caleb Kraft, secret genius, made a night light out of phosphorescent (the technical term is "glow-in-the-dark") algae, and you can, too. Here is how:

• Buy the algae.
• Put it in a transparent container.
• Make sure it's left in the light during the day.
• Shake it.

Really, that’s what it boils down to. Here, if you need more info, Caleb will explain.

Sure, we all loved Sesame Street. And we all incorporate its lessons into our daily adult lives, every time we count to 12, contemplate the people in our neighborhood, or find a new way to walk. But Reddit user dirtyduck383 has shown you all up in the Muppet fan department. He (OK, I don't know, but it's Reddit, so I'm going to guess "he") modded his bike to look like Cookie Monster.

It sucks to have to move. But it sucks less if you're moving from an old building to one in the exact same spot -- a new, fancier building, in which you have to pay only $10 for your new two-bedroom apartment.

Haha, right, and it also sucks less if Jeremy Renner carries your boxes and your new place is made out of candy! But seriously, though, the $10 apartment thing happened.

In New York's East Village, on the corner of First Street and Second Avenue, there used to be a small building with one of the neighborhood's most famously gritty and old-school bars.

Did you know that the city of Oslo is powered by garbage? Amazing and true. The Norwegian capital, home to about 650,000 residents, operates two enormous incinerators which supply the city with about 1.5 terawatt-hours of power. A terrawatt, by the way, is a trillion watts. In other words, it's a latt of watt. (I will be here all week.)

At any rate, this seems ideal, yes? There's no better use for garbage than to be burned up and transformed into something useful. Alas, in this heartless world nothing good can exist without its opposite existing simultaneously, and it is thus sad but not terribly surprising to hear that Oslo is now running out of garbage.
