Sam Van Aken is the creator of the Tree of 40 Fruit, a single tree that grows 40 different types of fruit.

Van Aken is an artist and professor at Syracuse University, and his latest project just might be his most delicious yet.

Van Aken's Tree of 40 Fruit grow a wide variety of stone fruits (i.e., fruits with large pits in the center), including cherries, plums, peaches, nectarines, apricots, and even almonds.

It's all possible through an intricate process called "chip grafting."

Van Aken takes a sliver off one of his dozens of small fruit trees.

Then, he makes a small cut on the branch of the established tree to bring them together.

Finally, he uses a special tape to seal everything, creating almost a small greenhouse right at the incision.

With some sunlight, water, and TLC, the two plants will grow together.

Hundreds of chip grafts and several years later, you have a Tree of 40 Fruit.

Since each variety of fruit blossoms at a different time, Van Aken meticulously plots the location of each branch, essentially designing and sculpting the tree from the ground up.

Each tree takes years to mature and develop, which means Van Aken has over a dozen trees in progress.

He likes to plant the trees in public spaces to encourage inquiry and spark conversation.

The trees can be seen everywhere from the campus of Syracuse University, to a hotel and gallery in Bentonville, Arkansas. There's even a small grove of eight trees at Thompson Point, a mixed-use retail area in Portland, Maine.

Each tree is meant to be shared, enjoyed, and pondered. The entire project toys with the viewer's concept of reality, and Van Aken enjoys straddling the border of truth and science fiction.

"Once they happen upon these trees, they would start to question, 'Why are the leaves shaped differently? Why are they different colors?'" he told National Geographic in a video profile earlier this year.

But this project is bigger than art — there are conservation implications as well.

Many of the seeds and plants Van Aken used for the project are no longer used by commercial growers because of size, shelf life, and, yes, even aesthetics. As Van Aken said in a recent TED talk, "People generally don't like a yellow plum."

The Tree of 40 Fruit puts the seeds and plants back to work. In an email with Upworthy, Van Aken said he's using proceeds from the sale of his trees to create an heirloom fruit orchard and field guide to study the precious plants.

The Tree of 40 Fruit is a living, breathing tasty work of art. And you can see it come to life in this short video by National Geographic:

Two years ago, I got off the phone after an interview and cried my eyes out. I'd just spent an hour talking to Tim Ballard, the founder of Operation Underground Railroad, an organization that helps fight child sex trafficking, and I just couldn't take it.

Ballard told me about how the training to go undercover as a child predator nearly broke him. He told me an eerie story of a trafficker who could totally compartmentalize, showing Ballard photos of kids he had for sale, then switching gears to proudly show him a photo of his own daughter on her bicycle, just as any parent would. He told me about how lucrative child trafficking is—how a child can bring in three or four times as much as a female prostitute—and how Americans are the industry's biggest consumers.

As you sit down to eat your breakfast in the morning or grab an afternoon snack, take a minute to consider your food, how it was made, and how it got to your plate.

The fruit on your plate were grown and picked on farms, then processed, packaged and sent to the grocery store where you bought them.

Sounds simple, right?

The truth is, that process is anything but simple and at every step in the journey to your plate, harm can be caused to the people who grow it, the communities that need it, and the planet we all call home.

For example, thousands of kids live in food deserts and areas where access to affordable and nutritious food is limited. Around the world, one in three children suffer from some form of malnutrition, and yet, up to 40% of food in the United States is never eaten.

I saw this poster today and I was going to just let it go, but then I kept feeling tugged to say something.

While this poster is great to bring attention to the issue of child trafficking, it is a "shocking" picture of a young girl tied up. It has that dark gritty feeling. I picture her in a basement tied to a dripping pipe.

While that sounds awful, it's important to know that trafficking children in the US is not all of that. I can't say it never is—I don't know. What I do know is most young trafficked children aren't sitting in a basement tied up. They have families, and someone—usually in their family—is trafficking them.

Most women, at one point or another, have felt some wariness or fear over a strange man in public. Sometimes it's overt, sometimes it's subtle, but when your instincts tell you something isn't right and you're potentially in danger, you listen.

It's an unfortunate reality, but reality nonetheless.

A Twitter thread starting with some advice on helping women out is highlighting how real this is for many of us. User @mxrixm_nk wrote: "If a girl suddenly acts as if she knows you in public and acts like you're friends, go along w[ith] it. She could be in danger."

Other women chimed in with their own personal stories of either being the girl approaching a stranger or being the stranger approached by a girl to fend off a situation with a creepy dude.
