By 2050, the Earth's population is expected to hit 9 billion (!). That means we're going to need to get creative to feed 2 billion more mouths every day.
How in the heck are we going to do that?
We already live in a world where nearly 800 million people suffer from chronic hunger. How are we supposed to get that number down while also sustaining a growing population?
One answer lies in our cities:
This video illustrates the need for food to be produced closer to where people live. As more people are moving to cities, hauling food products hundreds or thousands of miles from farms to grocery shelves isn't a sustainable option. That's why farms are moving into cities.
To feed everyone, we have to rethink where our food comes from.
The urban population of the world has been growing incredibly fast. In 1950, there were 746 million people living in urban areas. By 2014, that number jumped to 3.9 BILLION. And it only keeps increasing.
Within the next 30 years, it is expected that 70% of the world population will be located in urban areas, with most of the growth occurring in less developed countries.
The good news: We already produce enough food to feed 9 billion people. It's just not reaching the people who need it, and a third of all food produced is wasted. In other words, the major problems are access and waste.
In the United States alone, we waste enough food to fill up a 90,000-person football stadium EVERY. SINGLE. DAY.
One way to help with both the access and the waste problems is to grow food where people already are: in cities.

When you picture a farm, a city setting doesn't typically come to mind. But these days, it's becoming quite common to see farms on the tops of buildings, in small, communal plots of land, or in abandoned warehouses that beam with artificial light.
The traditional concept of farming in rural "farm country" has been broadened to more dense environments around the world, in cities with all types of weather and climate.

Yes, that means you can even grow food in the middle of a desert city like Dubai. Pretty cool!
Farming closer to home means the food is fresher, people are healthier, there's less food waste, and the environment is happier because of shorter distances from farm to table. And not only that, but urban plots can be up to 15 times more productive than rural ones, according to the United Nations Food and Agriculture Organization.
Growing food in urban areas is one answer to feeding more people, but it's just one piece of the puzzle.
To feed the world's growing population will require an equal focus on traditional agricultural practices in order for us to make real impact.

Up to 80% of the food consumed in Asia and sub-Saharan Africa is produced by female and smallholder farmers — many of them female. If we really want to close the hunger gap and feed more people, we must properly invest in their resources and growth to help boost their incomes and productivity with their yields.
There's a lot of work to be done before we're successfully able to feed an additional 2 billion people. It will take a global effort to find a sustainable balance between old and new agricultural practices.
It's cool to see that work in progress — quite literally, growing from a rooftop in the middle of a city.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
