Who ever thought you could fight the effects of drought just by mixing fruits together?

Science whiz Kiara Nirghin, a grade 11 student at St. Martin's School in Johannesburg, came up with an idea that could make a big difference in drought-stricken regions.

"Currently, South Africa is experiencing one of the worst droughts in its history," said Nirghin. "I started looking at it, and not only is it affecting my community, it's a worldwide problem. From there, I started looking at, 'OK. What could I do to lessen the impact that the drought had on South Africa's food supply?' — which is one of the main things that it is affecting."

With temperatures rising to blistering levels and South Africa declaring a state of disaster due to drought in eight provinces, Nirghin's game-changing invention couldn't have come at a better time.

Using orange peels and avocado skins, Nirghin created her own superabsorbent polymer (SAP) to nourish crops in desperate need of water.

An SAP is a powder-like material that can take in large amounts of liquid without taking up a lot of space. In fact, it's known to absorb hundreds of times its own weight. SAPs are planted alongside crops to create mini reservoirs of water that keep soil moist longer and allow growing plants to survive with less rainfall or water.

According to Science Direct, the problem with many SAPs is they're made from some pretty harsh chemicals that can harm people as well as the environment. So Nirghin set out to create a more natural, biodegradable alternative.

"I started looking at what characterized a superabsorbent polymer and how I could emulate that characterization," she said. "And one of those things were the polysaccharide found in orange peels."

Nirghin breaks down her process in a video for the Google Science Fair. First, she boiled the orange peels to extract pectin (more typically used as a gelling agent in jams and jellies). She then combined the pectin with sun-dried orange peels, baked the mixture, crushed it into a powder, and added more sun-dried orange peels and avocado skins.

The project, dubbed "No More Thirsty Crops," earned Nirghin the grand prize at this year's Google Science Fair.

Not only is Nirghin's SAP biodegradable, it's also affordable — and creating it produces less pollution than regular SAPs.

"[Commercial SAPs are] not biodegradable and they’re extremely costly," said Nirghin. "And one of the important aspects that’s often overlooked is that the making of the superabsorbent polymers pollutes the environment. … The production is not only timely, it’s very difficult to reproduce in poorer areas … So I looked at basically minimizing all those negative aspects."

In Nirghin's research paper, she estimates her SAP would cost about $30 to $60 per metric ton to mass produce — whereas current commercial SAPs can go for a staggering $2,000 to $3,000 per metric ton. Even better? Nirghin found her method to be more effective at retaining water than commercial SAPs.

Nirghin now has her sights set on getting her SAP in as many hands as possible and affecting more positive change around the world.

"I would love for it to go into actual farms out there," Nirghin said. "I want it to actually be supplied to farmers all over the world that are currently experiencing a drought. I don’t want to keep it as an idea that I just came up with … I would really like for it to go out and help people out there."

On top of her Google Science Fair victory, Nirghin's invention also garnered her a spot on Time's 30 Most Influential Teens of 2016 — an honor that could help her spread even more good. For starters, she's already looking to expand her SAP to test water filtration as well as oil removal from water.

Nirghin also has an inspiring message for anyone looking to follow in her footsteps.

She said, "One of the main things is looking at what your community is facing because it's great coming up with an idea, but unless it impacts your community and makes it better — like the Google Science Fair says, 'What will you make better?' — that should be one of the main driving forces to lessen the impact of the problems of your community."

From there, just think of that idea as a freshly planted crop. With a little nourishment and attention, it can grow into something even stronger and more essential than you ever imagined.

When a pet is admitted to a shelter it can be a traumatizing experience. Many are afraid of their new surroundings and are far from comfortable showing off their unique personalities. The problem is that's when many of them have their photos taken to appear in online searches.

Chewy, the pet retailer who has dedicated themselves to supporting shelters and rescues throughout the country, recognized the important work of a couple in Tampa, FL who have been taking professional photos of shelter pets to help get them adopted.

"If it's a photo of a scared animal, most people, subconsciously or even consciously, are going to skip over it," pet photographer Adam Goldberg says. "They can't visualize that dog in their home."

Adam realized the importance of quality shelter photos while working as a social media specialist for the Humane Society of Broward County in Fort Lauderdale, Florida.

"The photos were taken top-down so you couldn't see the size of the pet, and the flash would create these red eyes," he recalls. "Sometimes [volunteers] would shoot the photos through the chain-link fences."

That's why Adam and his wife, Mary, have spent much of their free time over the past five years photographing over 1,200 shelter animals to show off their unique personalities to potential adoptive families. The Goldbergs' wonderful work was recently profiled by Chewy in the video above entitled, "A Day in the Life of a Shelter Pet Photographer."

Just imagine being an 11-year-old boy who's been shuffled through the foster care system. No forever home. No forever family. No idea where you'll be living or who will take care of you in the near future.

Then, a loving couple takes you under their care and chooses to love you forever.

What could one be more thankful for?

That's why when a fifth grader at Deerfield Elementary School in Cedar Hills, Utah was asked by his substitute teacher what he's thankful for this Thanksgiving, he said finally being adopted by his two dads.

To the child's shock, the teacher replied, "that's nothing to be thankful for," and then went on a rant in front of 30 students saying that "two men living together is a sin" and "homosexuality is wrong."

While the boy sat there embarrassed, three girls in the class stood up for him by walking out of the room to tell the principal. Shortly after, the substitute was then escorted out of the building.

While on her way out she scolded the boy, saying it was his fault she was removed.

One of the boy's parents-to-be is Louis van Amstel, is a former dancer on ABC's "Dancing with the Stars." "It's absolutely ridiculous and horrible what she did," he told The Salt Lake Tribune. "We were livid. It's 2019 and this is a public school."

The boy told his parents-to-be he didn't speak up in the classroom because their final adoption hearing is December 19 and he didn't want to do anything that would interfere.

He had already been through two failed adoptions and didn't want it to happen again.

A spokesperson for the Alpine School District didn't go into detail about the situation but praised the students who spoke out.

"Fellow students saw a need, and they were able to offer support," David Stephenson said. "It's awesome what happened as far as those girls coming forward."

He also said that "appropriate action has been taken" with the substitute teacher.

"We are concerned about any reports of inappropriate behavior and take these matters very seriously," Kelly Services, the school the contracts out substitute teachers for the district, said in a statement. "We conduct business based on the highest standards of integrity, quality, and professional excellence. We're looking into this situation."

After the incident made the news, the soon-to-be adoptive parents' home was covered in paper hearts that said, "We love you" and "We support you."

Religion is supposed to make us better people.

But what have here is clearly a situation where a woman's judgement about what is good and right was clouded by bigoted dogma. She was more bothered by the idea of two men loving each other than the act of pure love they committed when choosing to adopt a child.
