It's Friday! It's March! It's almost spring! Let's celebrate like Heidi would by hanging out with baby goats.

We're gonna go craaaazy:

And do some goat hurdles:

Now we're on a bucket.  Now we're on a stump. On a stump! On a stump! Now we're on a bucket!

What is this thing you call "seesaw"?

Green Thing encourages people to walk more, cut back on meat, buy less, turn down the thermostat, waste and fly less, and unplug vampire electronics. So every day until Earth Hour on March 23, the London-based nonprofit is publishing a poster to promote those green habits.

And some big designer names contributed to the project, including Google Creative Director Tom Uglow and London 2012 Olympics logo designer Patrick Cox. Green Thing knows "that a dig, joke, or nudge is way more effective than another weeping seal cub,” Cox said in a press release for the project. Follow the project on Green Thing.

This bike is called the BlackBraid, and it weighs only 11 pounds. It's so light that even this little kid can lift it up over her head.

Fast Company explains how this magic happens:

The frame is of particular note. It’s what gives the bike its unbelievable lightness, and it’s also the BlackBraid’s namesake. Crafted from specially braided carbon fiber developed by a partner in Munich, the tubes have incredible rigidity, despite being mostly air. Carbon components have been sourced through much of the rest of the bike as well, including the chainwheel, sprocket, and chain.

The more readily available sugar is your country's food system, the more likely you are to get diabetes.

That's the conclusion an exhaustive worldwide study of diets, obesity rates, and Type 2 diabetes. It found that for every 150 calories of sugar that could be drunk or eaten daily by a resident of each of the countries studied, whether that sugar was squeezed out of sugar cane, beets, or corn, each resident became on average 1.1 percent more likely to develop the disease. (The researchers didn't analyze how many calories individuals actually eat and drink, but rather how many calories are available to people through their national food supply chains. Some of those calories are wasted without being consumed.)

A 12-ounce can of soda typically harbors about 150 sugary calories (which scientists, including the authors of the new study, confusingly call kilocalories). Many candy bars contain more calories than that, though not all from sugar.

Portland resident David Neevel's self-description as a "physicist and copywriter" leads one to suspect he has talents in neither field. But one thing is beyond a doubt: The man is capable of building an effective, if perhaps not elegant, Oreo-separating machine to satisfy his passionate "dislike for cream" and "preference for cookies."

The other thing that's beyond doubt is that he has a real scene-stealer of  mustache. I asked my friend Heather, "What do you call that kind of mustache?" and she said, "A health hazard."

Sometimes, ad agencies have amazing ideas. Like bikes that tweet while you ride them. Here’s how ad agency Razorfish came up with that concept for South by Southwest:

"What fun things can we do at South by?" "How about free bikes?" "How about free bikes that talk? Even better."

I love it when a plan comes together.

So now there will be 20 "self-tweeting" bicycles at South by Southwest, all of them free to use.

When a deer is stuck on a frozen lake, would you think to call a helicopter? I wouldn't, but luckily the Nova Scotian authorities who recently used the blast off of a low-flying helicopter to push a stranded deer to safety are more creative than I am.

Watch nature and technology dance their beautiful dance:

Mrs. Obama -- can I call you Michelle? -- do you have a minute? I know you’re on tour right now, but I think you and I need to have a little chat.

First off, childhood obesity is a major crisis, and your Let’s Move! anti-obesity campaign is an important initiative. The report your Presidential Task Force on Childhood Obesity produced was a landmark document, and you’ve brought new and essential attention to the ways the nation must address the obesity and diabetes epidemic.

But your latest move? Expecting the processed-food companies and retail giants to spearhead the move to healthy eating? It’s just not going to happen. I hope that’s not too harsh, but I wanted to be straight with you after reading your recent op-ed in the Wall Street Journal, “The Business Case for Healthier Food.” In it, you declare that:

Every day, great American companies are achieving greater and greater success by creating and selling healthy products. In doing so, they are showing that what's good for kids and good for family budgets can also be good for business.

And then you laud Walmart and Walgreens for expanding their selection of fresh fruits and vegetables and Disney for “eliminating ads for junk foods from its children’s programming.”

Kudos to them, but that’s all about “selling.” What about “creating”? You give a nod to restaurants “cutting calories, fat and sodium from menus and offering healthier kids' meals.” Now, that’s not nothing: Americans spend 40 percent of our food budgets eating out. But the rest goes to food we eat at home, and of that, we spend over 20 percent on processed food, and about 8 percent on soda and other sweetened beverages. That’s a big chunk of our daily caloric intake, not to mention our paychecks. And it’s not something you can ignore when you’re talking about any business case involving food.

You did once call on food companies to improve their products. Do you remember that time you went in front of the Grocery Manufacturers Association and said this?

We need you not just to tweak around the edges, but to entirely rethink the products that you’re offering, the information that you provide about these products, and how you market those products to our children. ...

While decreasing fat is certainly a good thing, replacing it with sugar and salt isn’t. And it doesn’t mean compensating for high amounts of problematic ingredients with small amounts of beneficial ones — for example, adding a little bit of Vitamin C to a product with lots of sugar, or a gram of fiber to a product with tons of fat doesn’t suddenly make those products good for our kids ... This isn’t about finding creative ways to market products as healthy. As you know, it’s about producing products that actually are healthy — products that can help shape the health habits of an entire generation.

Right on!

Except that was three years ago, and you’ve said not a peep on that subject since then. Instead we get empty platitudes on how healthy food is good for business. Well, the processed-food industry knows that what’s really good for business is engineering food products that hit consumers’ “bliss point” of flavor and texture.

Repurpose an afghan, Stan. Trade out a shirt, Curt. Don’t need corduroy, Joy. Just listen to me.

Some tricks for building collective wardrobes are as old-fangled as Garfunkel's turtleneck, while others are new. Here are five of the best.

1. Leasing

Gone are the days when the only rentable clothing was regrettable men’s prom wear. Now, you can lease high-end dresses from Rent The Runway and Lending Luxury, and designer purses from Bag Borrow or Steal.

While this is dandy for formal events, if you’re like me, your idea of everyday luxury is a shirt with no visible holes and/or marinara stains. Renting something for daily wear seems far-fetched, obtuse. Not to mention, not-so-sustainable. If you’re so caught up in trends that you need to constantly update your wardrobe, the clothing selection’s rentability will diminish faster than your wallet and green cred.

Two sites that bridge the gap nicely are Mine for Nine for maternity rentals and thredUP for kid’s clothes. While we obviously don’t want y’all getting pregnant just so you can rent some flexi-pants and OshKosh B’goshes, it makes sense to quit buying clothing for rapidly changing bodies.

A few weeks ago, the Department of Agriculture released a pretty devastating report on just how bad climate change is going to suck for things we plant in the ground in America. Short version: T minus 25ish years until we hit Armageddon-like scenarios for agriculture and forests.

That might sound hopeless, but Agriculture Secretary Tom Vilsack is not discouraged. The Natural Resources Defense Council's Switchboard blog reports on a followup speech Vilsack gave this week, saying the USDA will help farmers adapt to climate change and become part of the climate solution.

"We're going to be very aggressive in this effort because we understand and appreciate, after the floods of 2011 and the drought of 2012, that folks need this assistance now," said Vilsack. "And by doing this, by taking these actions, we can help to mitigate and help to manage risks."
