This incredible mural was made from car exhaust. Yes, really.

Anirudh Sharma remembers the air pollution growing up in India — he just didn't remember it being so bad.

When he took a trip home in 2013, while on break as a student at MIT's Media Lab, the difference in air quality between India and Boston couldn't have been starker.

“It was a very simple observation — I feel like anybody can see it," Sharma says of the pollution's effects in his home country. "Your clothes get dirtier much faster, you can see this pigmentation happening [on] buildings, to your clothes, to everywhere around you."

Sharma found himself wondering: Is there any way to put this awful black gunk to good use? He realized how similar the soot was to the black ink in your standard ballpoint pen, and the comparison prompted him to begin digging deeper.

Inspired by what he saw on his trip, Sharma and fellow co-founder Nikhil Kaushik launched Graviky Labs.

The team is the mastermind behind Air-Ink — an ink that's made from the dirty black pollution emitted from vehicles.

As you can imagine, it takes a few steps to go from air pollution to black ink that's safe for anyone to use.

First, Sharma and his team came up with what they dubbed a "Kaalink" — a device that connects with a vehicle's exhaust pipe to collect soot and pollutants that would otherwise be jetting out into the open air while the engine is running.

Graviky Labs then takes the soot and pollutants and removes harmful or unnecessary materials — like metals and carcinogens — so all that's left is a carbon rich pigment that can be made into various inks and paints.

As of now, Air-Ink is available in various sizes of markers, as well as a printing ink set — and the process of making them is smart for a few reasons.

The obvious positive aspect to Air-Ink is that it prevents pollutants from getting into the atmosphere, keeping our air healthier to breathe. But it also curbs our reliance on conventional ink-making methods that rely on the deliberate burning of fossil fuels to get the job done, Graviky Labs notes.

“We are trying to not only capture pollution and recycle pollution," Kaushik explains, but they're also ensuring less carbon is being emitted from other ink-making sources.

In other words, it's a win-win.

Of course, it also helps that the ink can produce some pretty incredible works of art.

Right now, Air-Ink is only available through a Kickstarter campaign, which is aiming to expand Graviky Labs' operations.

Through funds raised online, Sharma's team is planning to also create oil-based, fabric, and outdoor paints. And from the looks of it, Air-Ink is on the right track to success.

With three weeks still left to go of the campaign, Graviky Labs' Kickstarter has already surpassed its initial fundraising goal of nearly $10,000.

"It feels great,” co-founder Kaushik says of the campaign's success thus far. “We have heard from a lot of people that they want to use it."

Air-Ink won't solve the world's air pollution problems in the long-term. But it's the right type of idea the world needs now.

Most eco-friendly innovations combating climate change and curbing pollution are expensive "replacement" technologies — such as electric cars replacing gas-powered ones — and other things that take longer to go mainstream economically, according to Kaushik. Over the next few years, however, it'll be crucial that we develop less expensive adaptations that can be applied to current technologies (even those as basic as ink production) that will help make the planet greener in the meantime. That's where innovations like Air-Ink come in.

“This is something that can help," Kaushik says. "But it has to be part of a bigger system where other technologies and other innovations pitch in."

I'm staring at my screen watching the President of the United States speak before a stadium full of people in North Carolina. He launches into a lie-laced attack on Congresswoman Ilhan Omar, and the crowd boos. Soon they start chanting, "Send her back! Send her back! Send her back!"

The President does nothing. Says nothing. He just stands there and waits for the crowd to finish their outburst.

My mind flashes to another President of the United States speaking to a stadium full of people in North Carolina in 2016. A heckler in the crowd—an old man in uniform holding up a TRUMP sign—starts shouting, disrupting the speech. The crowd boos. Soon they start chanting, "Hillary! Hillary! Hillary!"

What will future generations never believe that we tolerated in 2019?

Dolphin and orca captivity, for sure. They'll probably shake their heads at how people died because they couldn't afford healthcare. And, they'll be completely mystified at the amount of food some people waste while others go starving.

According to Biological Diversity, "An estimated 40 percent of the food produced in the United States is wasted every year, costing households, businesses and farms about $218 billion annually."

There are so many things wrong with this.

First of all it's a waste of money for the households who throw out good food. Second, it's a waste of all of the resources that went into growing the food, including the animals who gave their lives for the meal. Third, there's something very wrong with throwing out food when one in eight Americans struggle with hunger.

Supermarkets are just as guilty of this unnecessary waste as consumers. About 10% of all food waste are supermarket products thrown out before they've reached their expiration date.

Three years ago, France took big steps to combat food waste by making a law that bans grocery stores from throwing away edible food.According to the new ordinance, stores can be fined for up to $4,500 for each infraction.

Previously, the French threw out 7.1 million tons of food. Sixty-seven percent of which was tossed by consumers, 15% by restaurants, and 11% by grocery stores.

This has created a network of over 5,000 charities that accept the food from supermarkets and donate them to charity. The law also struck down agreements between supermarkets and manufacturers that prohibited the stores from donating food to charities.

"There was one food manufacturer that was not authorized to donate the sandwiches it made for a particular supermarket brand. But now, we get 30,000 sandwiches a month from them — sandwiches that used to be thrown away," Jacques Bailet, head of the French network of food banks known as Banques Alimentaires, told NPR.

It's expected that similar laws may spread through Europe, but people are a lot less confident at it happening in the United States. The USDA believes that the biggest barrier to such a program would be cost to the charities and or supermarkets.

"The logistics of getting safe, wholesome, edible food from anywhere to people that can use it is really difficult," the organization said according to Gizmodo. "If you're having to set up a really expensive system to recover marginal amounts of food, that's not good for anybody."

Plus, the idea may seem a little too "socialist" for the average American's appetite.

"The French version is quite socialist, but I would say in a great way because you're providing a way where they [supermarkets] have to do the beneficial things not only for the environment, but from an ethical standpoint of getting healthy food to those who need it and minimizing some of the harmful greenhouse gas emissions that come when food ends up in a landfill," Jonathan Bloom, the author of American Wasteland, told NPR.

However, just because something may be socialist doesn't mean it's wrong. The greater wrong is the insane waste of money, damage to the environment, and devastation caused by hunger that can easily be avoided.

Policing women's bodies — and by consequence their clothes — is nothing new to women across the globe. But this mother's "legging problem" is particularly ridiculous.

What someone wears, regardless of gender, is a personal choice. Sadly, many folks like Maryann White, mother of four sons, think women's attire — particularly women's leggings are a threat to men.

While sitting in mass at the University of Notre Dame, White was aghast by the spandex attire the young women in front of her were sporting.

Men are sharing examples of how they step up and step in when they see problematic behaviors in their peers, and people are here for it.

Twitter user "feminist next door" posed an inquiry to her followers, asking "good guys" to share times they saw misogyny or predatory behavior and did something about it. "What did you say," she asked. "What are your suggestions for the other other men in this situation?" She added a perfectly fitting hashtag: #NotCoolMan.

Not only did the good guys show up for the thread, but their stories show how men can interrupt situations when they see women being mistreated and help put a stop to it.
