It's not an elaborate treehouse — it's a new affordable housing concept.

This Dutch architect's big idea makes even our 'greenest' cities look gray.

What kinds of places do you think of when it comes to "green" cities?

If you're like me, you're probably imagining places with subways and solar panels, electric cars and urban farms. And you'd be right. Those things are important for a city to be considered "green."

A 2015 study of the nation's 150 largest cities by Nerd Wallet ranked eco-friendliness by looking at where people live, how they get around the city, where their energy comes from, and the quality of the air. Some examples of the nation's greenest cities include...

But what if I told you green cities could look like this:

This is OAS1S, the brain baby of Dutch architect Raimond de Hullu.

It's his template for building cities that are green in the truest sense of the word. In an interview with Fast Company, De Hullu explained his vision:

"We need a new building typology that goes beyond the usual technical sustainability. We need a 100% green concept, not only technically but visually as well, and which is desirable plus affordable at the same time."

De Hullu envisions buildings that take after trees, nature's original skyscrapers...

...and communities that blend with forests.

He imagines neighborhoods built entirely from recycled materials that function completely off-grid with solar energy and on-site water systems.

And best of all, he wants OAS1S to be an affordable housing opportunity. For everyone.

To achieve that, he wants these communities to be set up as land trusts. Under this model, a community nonprofit is formed to buy and own land, and the homes built on that land are owned by the occupants. According to the Democracy Collaborative:

"By separating the ownership of land and housing, this innovative approach prevents market factors from causing prices to rise significantly, and hence guarantees that housing will remain affordable for future generations."

OAS1S is still only a concept, but de Hullu is searching for a suitable place for a pilot community.

He hopes the first location can be in an established city, which would be great for visibility, especially if it proves an effective model.

But he also sees value in piloting OAS1S in a less developed vacation setting.

Either way, de Hullu wants the essence of the project to remain "constructing a true balance between architecture and nature."

De Hullu's goal is simple: build communities that are good for people and good for the planet.

And the last thing, which I cannot stress enough, is that we could live in tree houses!

How cool would that be?

Andy Grammer, the pop singer and songwriter behind feel-good tunes like "Keep Your Head Up," "Back Home," and "Don't Give Up on Me," has a new album out—and it is seriously fabulous. Titled simply "Naive," Grammer says it's "all about how seeing the good in todays world can feel like a rebellious act."

"I wrote this album for the light bringers," Grammer shared on Facebook. "The people who choose to see the good even in the overwhelming chaos of the bad. The smilers who fight brick by brick to build an authentic smile everyday, even when it seems like an impossible thing to do. For those who have been marginalized as 'sweet' or 'cute' or 'less powerful' for being overly positive. To me optimism is a war to be fought, possibly the most important one. If I am speaking to you and you are relating to it then know I made this album for you. You are my tribe. I love you and I hope it serves you. Don't let the world turn down your shine, we all so badly need it."

Reading that, it's easy to think maybe he really is naive, but Grammer's positivity isn't due to nothing difficult ever happening in his life. His mom, Kathy, died of breast cancer when Grammer was 25. He and his mother were very close, and her life and death had a huge impact on him.

Service dogs are invaluable to their owners because they are able to help in so many different ways.

They're trained to retrieve dropped Items, open and close doors, help their owners remove their clothes, transport medications, navigate busy areas such as airports, provide visual assistance, and even give psychological help.

The service dog trainers at K-9 Country Inn Working Service Dogs in Canada want those who require service dogs to live the fullest life possible, so they're training dogs on how to attend a theatrical performance.

The adorable photos of the dogs made their way to social media where they quickly went viral.

On August 15, a dozen dogs from Golden Retrievers to poodles, were treated to a performance of "Billy Elliott" at the Stratford Festival in Ontario, Canada. This was a special "relaxed performance" featuring quieter sound effects and lighting, designed for those with sensory issues.

"It's important to prepare the dogs for any activity the handler may like to attend," Laura Mackenzie, owner and head trainer at K-9 Country Inn Working Service Dogs, told CBC.

"The theater gives us the opportunity to expose the dogs to different stimuli such as lights, loud noises, and movement of varying degrees," she continued. "The dogs must remain relaxed in tight quarters for an extended period of time."

The dogs got to enjoy the show from their own seats and took a break with everyone else during intermission. They were able to familiarize themselves with the theater experience so they know how to navigate through crowds and fit into tight bathroom stalls.

"About a dozen dogs came to our relaxed performance, and they were all extremely well-behaved," says Stratford Festival spokesperson Ann Swerdfager. "I was in the lobby when they came in, then they took their seats, then got out of their seats at intermission and went back — all of the things we learn as humans when we start going to the theater."

The dogs' great performance at the trial run means that people who require service animals can have the freedom to enjoy special experiences like going to the theater.

"It's wonderful that going to the theater is considered one of the things that you want to train a service dog for, rather than thinking that theater is out of reach for people who require a service animal, because it isn't," Swerdfager said.

The Stratford Festival runs through Nov. 10 and features productions of "The Merry Wives of Windsor," "The Neverending Story," "Othello," "Billy Elliot," "Little Shop of Horrors," "The Crucible" and more.

Graphic helps identify what triggers you emotionally in relationships

Knowing your triggers helps you manage your emotions.

Learning your emotional triggers on your own is one thing but figuring out your triggers in a relationship adds another layer of intensity. Maybe you're afraid of being abandoned or want to feel the need to push the other person away but you don't know why.

If this sounds familiar, you're not alone. It's why artist and mental health advocate Dominee Wyrick created a graphic to help you identify what triggers you in relationships.

15 'habits' of people who grew up with an 'emotionally fragile' parent

Having an emotionally fragile parent can leave lasting damage.

via The Mighty

If you grew up with an "emotionally fragile" parent, chances are, you didn't have the typical, idyllic childhood you often see in movies.

Maybe your parent lived with debilitating depression that thrust you into the role of caregiver from a very young age.

Maybe your parent was always teetering on the edge of absolute rage, so you learned to tiptoe around them to avoid an explosion. Or maybe your parent went through a divorce or separation, and leaned on you for more emotional support than was appropriate to expect of a child.
