In a world where intelligence often equates to acclaim, one woman’s extraordinary IQ score—higher than those of Einstein, Stephen Hawking, and Elon Musk—should have made her a universal icon. Yet, despite setting a record that still stands unmatched, her correct answer to a seemingly straightforward question sparked an avalanche of ridicule that overshadowed her brilliance. This is the woman with the highest recorded IQ who, in spite of the fact, found herself at the center of a controversy that questioned more than just her intelligence. What was the question, and why did it provoke such outrage?

The Infamous Monty Hall Problem

The Monty Hall Problem is one of the most fascinating riddles in the history of brainteasers. This mathematical puzzle, which takes its name from the host of the well-known game show “Let’s Make A Deal,” captures a situation that seems straightforward at first glance but is full of unexpected options.

Here’s the essence of the problem, as sent by a reader to the “Ask Marilyn” column in Parade in 1991:

“Suppose you’re on a game show, and you’re given the choice of three doors: Behind one door is a car; behind the others, goats. You pick a door, say No. 1, and the host, who knows what’s behind the other doors, opens another door, say No. 3, which has a goat. He then asks you, ‘Do you want to switch to door No. 2?’ Is it to your advantage to switch your choice?”

The roots of the problem trace back to its namesake, Monty Hall, and the game show dynamics where contestants faced similar choices, albeit without explicit reference to the underlying probabilities. The puzzle taps into fundamental aspects of probability and human psychology, where the correct choice defies our intuitive expectations.

The puzzle’s ongoing appeal stems from its defiance of common sense; although mathematical analysis shows that switching doors really doubles the likelihood of winning the car, intuition indicates that there is no benefit to doing so. Because of its illogical solution, the Monty Hall Problem is frequently discussed and examined in both scholarly and popular contexts.

A Woman’s Answer That Sparked a Firestorm of Ridicule

Marilyn Vos Savant, the woman behind the popular “Ask Marilyn” column, inadvertently ignited a firestorm with her straightforward response to the Monty Hall problem. When posed with the dilemma of whether to switch doors on a game show, she replied confidently: “Yes, you should switch. The first door has a 1/3 chance of winning the car, but the second has a 2/3 chance of winning the car.” This advice, however, did not sit well with a broad swath of her audience.

The backlash was quick and severe. Vos Savant’s column typically addressed a wide array of questions with crisp, clear logic, but this particular answer drew unprecedented ire. Over 10,000 letters poured in, many from incensed readers who vehemently disagreed with her logic. The criticism ranged from pedantic corrections to outright insults.

One particularly harsh letter stated, “You blew it, and you blew it big! Since you seem to have difficulty grasping the basic principle at work here, I’ll explain.”

Moreover, the controversy wasn’t limited to lay readers. A The New York Times article noted that among the disparaging responses, “close to 1,000 carried signatures with Ph.D.’s, and many were on letterheads of mathematics and science departments.”

“Your logic is in error, and I am sure you will receive many letters on this topic from high school and college students. Perhaps you should keep a few addresses for help with future columns,” read one letter from Georgia State University.

Another letter from Georgetown University said, “If you can admit your error you will have contributed constructively toward the solution of a deplorable situation. How many irate mathematicians are needed to get you to change your mind?”

A PhD doctor from the University of Michigan even invoked the Father of Modern Physics, saying, “Albert Einstein earned a dearer place in the hearts of people after he admitted his errors.”

This academic uproar reflected not just a misunderstanding of the problem’s underlying statistics but also deeper biases.

One letter even suggested a gendered difference in mathematical reasoning: “Maybe women look at math problems differently than men.” Another simply insulted her, proclaiming, “You are the goat!”

She Was Right All Along

The response Marilyn Vos Savant gave to the Monty Hall problem caused an uproar that necessitated not just one, but three follow-up columns to clarify her reasoning.

When initially presented with three doors, the chances of choosing the car were 1 in 3. After the host, who knows what’s behind each door, opens one to reveal a goat, the likelihood doesn’t split evenly between the remaining two doors as intuition might suggest. Instead, Vos Savant explained, “The winning odds of 1/3 on the first choice can’t go up to 1/2 just because the host opens a losing door.” Mapping out various scenarios reveals that switching doors indeed offers a two-thirds (66.6%) chance of winning, while sticking with the original choice gives only a one-third (33.3%) chance.

This counterintuitive outcome is better understood through a more exaggerated illustration. Imagine the game show presented you with 100 doors. You pick door #1, giving you a 1/100 chance of finding the car. The host then opens 98 other doors, all hiding goats, leaving just door #1 and another, say door #100. Although it might seem your odds have improved with fewer doors, the probability that the car is behind door #100 is now 99/100, significantly higher than the slim 1/100 chance that it remains behind your initial pick.

Monty Hall himself commented on the psychological aspects of the game, which further complicate player decisions. He noted that the more he offered contestants cash not to switch, the more convinced they became that their initial choice was correct—a psychological anchoring effect that clouded their judgment.

This cognitive dissonance—where new information (like the improved odds of switching doors) conflicts with existing beliefs (that each remaining door has equal probability)—explains much of the resistance to Vos Savant’s correct explanation. People tend to cling to their initial beliefs, even in the face of contradictory evidence, leading to widespread public and academic error.

Ultimately, computer simulations and classroom demonstrations across the country validated Vos Savant’s logic. Over time, the tide of opinion shifted dramatically: by the end of 1992, support among readers rose from 8% to 56%, and among academics from 35% to 71%.

Robert Sachs, a math professor who initially criticized Vos Savant, epitomized the changing attitudes when he later wrote to her, acknowledging his mistake: “After removing my foot from my mouth I’m now eating humble pie,” he admitted, vowing to personally respond to those he had led astray. “I vowed as penance to answer all the people who wrote to castigate me. It’s been an intense professional embarrassment.”

Getting to Know Marilyn Vos Savant

Marilyn Vos Savant, who gained widespread recognition not only for her prolific “Ask Marilyn” column but also for recording the highest IQ according to the Guinness Book of World Records, has been a subject of fascination and respect. Her IQ, reportedly higher than historical geniuses like Albert Einstein, Stephen Hawking, and contemporaries such as Elon Musk, places her in a unique position within the public and academic spheres.

Born in 1946 in St. Louis, Missouri, Vos Savant made headlines in the mid-1980s when her intellectual achievements were first publicized. Her exceptional cognitive abilities became the cornerstone for her weekly column in Parade magazine, where she solved complex mathematical problems and answered queries from readers about various subjects, demonstrating her broad range of knowledge and analytical prowess.

The Monty Hall problem brought her an unusual kind of celebrity, primarily due to the overwhelming flood of criticism following her counterintuitive but correct solution. Despite being correct, her response drew sharp rebukes from both the public and professionals in the fields of mathematics and science. The criticism was often harsh and personal, challenging her intellectual capacity and integrity. Yet, Vos Savant handled the situation with remarkable grace and patience.

In addressing the criticism, Vos Savant maintained a composed and educative tone, using the opportunity to further elucidate her reasoning in subsequent columns. Her responses were clear, methodical, and maintained a focus on educating her detractors, rather than defending her ego. She illustrated the principles of probability with simple, understandable examples, and invited readers to test the scenario themselves, promoting a deeper understanding of the problem.

Vos Savant’s demeanor during this period exemplified her grace in rational discourse and education. Rather than retreating or responding in kind to often vitriolic attacks, she continued to engage with her audience, patiently explaining and expanding on her reasoning and standing firm on her analysis. Her approach not only underscored her intellectual integrity but also highlighted her role as a public educator.

Beyond the Monty Hall controversy, Marilyn vos Savant has authored several books, imparting her wisdom on topics ranging from general intelligence to personal philosophy. Her work continues to inspire those who value intellect and reason, and her life remains a testament to the virtues of intelligence, patience, and resilience in the face of public scrutiny.

Inspiration From a Woman’s Triumph

Marilyn vos Savant’s encounter with the Monty Hall problem not only showed a fascinating statistical puzzle but also spotlighted deeper societal issues, such as the persistence of sexism and misogyny, even within educated and intellectual communities. The backlash she faced, steeped in gender bias, as evident from dismissive comments about “female logic” and overly personal critiques, underscored a troubling reality: intellectual arenas are not immune to the biases that pervade society at large.

Despite the storm of criticism, vos Savant navigated the controversy with remarkable grace and steadfastness, focusing on educating rather than retaliating. Her method of dealing with criticism—utilizing clarity to explain her reasoning and encouraging skeptics to test the problem themselves—transformed a contentious debate into a valuable teachable moment. This approach not only demonstrated the power of education in overcoming misinformation but also reinforced the importance of standing by one’s understanding and knowledge, even when faced with overwhelming opposition.

This goes to show that her story is a compelling chapter in the broader narrative of women in science and academia, offering inspiration and important lessons on resilience, clarity, and integrity in the pursuit of truth.

Let’s take a look at a few cities that are taking big steps toward a greener future.

Boston: Making Public Transit a Top Choice

Boston is on a mission to get more people out of their cars and onto public transit. The city wants to cut single-occupancy car trips in half by 2030, and they’re starting with a pilot program that’s giving free transit and bike passes to 1,000 residents in neighborhoods that were hit hard by the pandemic. The idea is simple: make transit more accessible and affordable, so people choose it over driving.

Early results have been promising, with bus and subway use tripling among those who received the passes. Building on this success, Boston has even used pandemic relief funds to keep some bus routes fare-free. This isn’t just about cutting emissions; it’s about making commuting more affordable and convenient, especially for those who need it most.

Columbus: Clean Energy with a Focus on Jobs

Columbus, Ohio, has set ambitious goals for reducing emissions—45% by 2030—but they’re also focused on creating opportunities for the community along the way. Through the Clean Energy Columbus initiative, the city is working to generate renewable energy with a special focus on job creation. This approach is expected to create up to 4,000 new jobs in Ohio, especially for underrepresented groups like people of color, women, and low-income youth.

What’s unique about Columbus’s plan is how they’re tying climate action to economic growth. The city is proving that clean energy isn’t just good for the environment; it’s also a chance to build a more inclusive economy. As Columbus’s Chief Sustainability Officer put it, having a clear vision for both the environment and community support helps to keep everyone aligned and motivated.

Honolulu: Reducing Traffic and Emissions with Rapid Transit Upgrades

Honolulu, famous for its beautiful beaches—and its traffic jams—is turning to clean transit to make commuting smoother and greener. The city recently fast-tracked a new bus lane on King Street, its busiest street, cutting commute times and making public transit more appealing. This project happened much faster than usual thanks to collaboration across four city departments, reducing the timeline by about a year.

The King Street bus lane is already making a difference, cutting down on delays and helping more people choose public transit over driving. This model is now being used to speed up other transit projects in Honolulu, including future bike and pedestrian paths. It’s a small but powerful shift that shows how making transit faster and more reliable can reduce emissions and ease daily commutes.

The city’s goal with Evie Carshare is to make the benefits of electric vehicles available to everyone, not just those who can afford to buy one. St. Paul’s Chief Resilience Officer explained that the community wanted climate action to be inclusive and accessible, and this program is a step in that direction. It’s a reminder that when it comes to climate solutions, accessibility and equity matter just as much as technology.

Transformative Climate Resilience Projects

As climate change brings more intense weather, cities are facing new risks like extreme heat, floods, and storms. Some cities are taking these challenges head-on, putting plans in place to protect people and infrastructure from the effects of a changing climate. The goal isn’t just to react to problems after they happen, but to build resilience so that urban life can withstand what’s to come.

Austin: Fighting Urban Heat with Trees

In Austin, Texas, the summer heat can feel relentless, especially in neighborhoods packed with concrete and fewer trees. Austin’s solution? Invest in “urban greening”—adding more trees and green spaces to cool down the city naturally. Their Climate Equity Plan aims to increase the city’s tree canopy, with a focus on planting in historically underserved neighborhoods where extreme heat hits the hardest.

Studies have shown that more tree coverage can cool urban temperatures by up to 9°F, which is huge during heatwaves. For Austin, it’s about more than just cooling the city; it’s about creating a fairer, healthier environment for everyone, especially those who have been impacted by climate change the most.

Tokyo: Climate-Proofing Buildings for Extreme Weather

Tokyo, Japan, has to contend with earthquakes, typhoons, and flooding, all of which are becoming more frequent and severe. To prepare, Tokyo has adopted some of the most advanced building codes in the world. New buildings are now designed to withstand everything from powerful earthquakes to heavy storms, using special materials and construction techniques like seismic base isolation systems.

This proactive approach has made Tokyo a model for resilience. According to a report by the World Bank, these climate-proof buildings could reduce economic losses from natural disasters by up to 30% in urban areas. For Tokyo, it’s about safety, but it’s also about keeping the city functioning smoothly, no matter what the weather brings.

New York City: Protecting Public Transit from Future Floods

When Hurricane Sandy hit New York City in 2012, it flooded the subway system, shutting down transit for days. Since then, the city has invested heavily in making the subway more resilient. Flood barriers, raised entrances, and waterproofed equipment are just a few of the upgrades New York has made to protect this essential part of the city’s infrastructure.

Now, the subway is better prepared to handle extreme weather events, reducing potential damage by half compared to pre-Sandy conditions. For a city like New York, where millions rely on public transit daily, these improvements are critical. They show how a little foresight can go a long way in protecting city life from the worst effects of climate change.

Each of these projects is more than just a protective measure—they’re part of a larger shift toward building cities that can adapt to and thrive in an uncertain climate. When cities invest in resilience, they’re not just preparing for tomorrow’s challenges; they’re making life better today.

The “15-Minute City” – Living Close, Living Green

Imagine a city where everything you need—your job, groceries, parks, schools—is just a short walk or bike ride away. That’s the vision behind the “15-Minute City.” It’s a way of designing neighborhoods so people don’t have to drive to get things done. This idea isn’t just better for the environment; it also helps build closer, friendlier communities.

Here’s how two cities are making this vision a reality.

Melbourne: Building “20-Minute Neighborhoods”

Melbourne, Australia, is bringing this idea to life with its “20-Minute Neighborhood” plan. The goal? Make sure that essential services are close enough that people can walk, bike, or use public transit to reach them in 20 minutes or less.

Studies from the University of Melbourne show these neighborhoods do more than cut traffic—they actually make people feel more connected and less stressed. It’s pretty simple: less time in the car means more time with family and friends. Melbourne is proving that planning for the planet can also make life better and simpler for everyone.

Paris: Bringing Life Closer to Home

Paris has taken the “15-Minute City” idea to heart. Led by Mayor Anne Hidalgo, the city is changing its streets to make them more welcoming for walking and biking. They’ve added green spaces, cut back on car lanes, and made neighborhoods feel more open and inviting.

The changes are already paying off. More people are choosing to walk or bike instead of drive, and neighborhoods feel more lively. By making essentials easy to reach, Paris is showing that city life can be less hectic and more community-focused. It’s a powerful example of how smart design can make cities better places to live.

The “15-Minute City” isn’t just about lowering emissions. It’s about creating neighborhoods where people have everything close by and life feels more connected. As more cities try out this idea, urban living could become greener, simpler, and a lot more enjoyable.

Cities Making a Real Difference

Cities around the world are showing us that change is possible, and it’s already happening. They’re finding smart ways to clean up the air, reduce traffic, create green spaces, and make city life better overall. These changes aren’t just good for the environment—they’re helping people live healthier, happier lives.

Think of a city where everything is close by, the air feels cleaner, and there are more places to relax and enjoy the outdoors. That’s what these cities are building. They’re not just preparing for the future—they’re making life better today.

What’s even more exciting is that they’re setting an example for others. If more cities join in, we’ll see urban living shift into something greener, friendlier, and more connected. It’s a big job, but with cities like these leading the way, we’re heading toward a brighter, more sustainable future.

As people age, the desire for independence remains strong, but so does the need for support. Many families find themselves caught between traditional elder care options and the challenges of inviting aging loved ones into their own homes. Assisted living facilities can feel impersonal, while the thought of moving grandparents into an already busy household might disrupt delicate family rhythms. Enter the “granny pod”—a compact, backyard home designed to bring loved ones closer without compromising their sense of self.

Granny pods, or accessory dwelling units (ADUs), are redefining senior living by combining privacy with proximity. Equipped with thoughtful features and tailored to fit nearly any family’s space, they offer a unique balance of autonomy and care that’s hard to find elsewhere. Imagine a cozy, self-contained home with just the right touch of tech and safety features, all nestled in the backyard, allowing grandparents to stay near without fully integrating into the main house.

But how exactly do these tiny homes work, and what makes them such a powerful alternative to traditional elder care? As families seek more meaningful, flexible options, granny pods are emerging as one of the most intriguing trends in multi-generational living.

What Are Granny Pods?

Granny pods, also known as accessory dwelling units (ADUs) or in-law cottages, are small, independent living spaces designed to house aging family members close to their loved ones. Typically set up in a family’s backyard, these compact homes are usually 300 to 500 square feet, though some models range up to 900 square feet. They include essential amenities like a bedroom, bathroom, kitchenette, and living area, designed to meet seniors’ needs for accessibility and safety. While these units are modest in size, they are meticulously crafted with features that enhance mobility, security, and comfort, creating an ideal balance between independence and nearby family support.

Most granny pods are prefabricated and can be installed directly on a property with hookups to the main house’s utilities, including water, electricity, and sewer. MEDCottage, one of the leading manufacturers, offers these pods in several models, catering to various needs. For instance, the MEDCottage Classic is a popular standalone option equipped with soft flooring, safety railings, and accessible bathrooms, helping minimize fall risks and ensuring ease of movement. Other versions, like the Living Roo, are adaptable to garage spaces, often featuring tech-forward touches like high-definition monitors for outdoor views, making the pods feel more spacious and connected to nature.

Granny pods are gaining traction as a compassionate alternative to nursing homes, especially as studies highlight the emotional and psychological benefits of seniors aging close to family. Research suggests that seniors who remain within their family’s vicinity experience reduced isolation, which positively impacts their mental and physical well-being. Moreover, the layout and features of these pods, such as rounded countertops and slip-resistant floors, cater directly to the unique safety concerns of older adults, who may be more prone to accidents at home if these factors are overlooked​.

High-Tech and Safety Features for Senior Independence

Granny pods are not just compact living spaces; they’re equipped with advanced features that prioritize safety, accessibility, and health monitoring to support seniors living independently. These “tiny homes” often include technology for round-the-clock monitoring and specialized installations designed to minimize risks for older adults. For instance, many granny pods incorporate padded floors and safety railings to prevent falls—a significant concern for aging individuals. Features like lighted floorboards and widened doorways further enhance accessibility and reduce hazards, allowing seniors to move safely even in low light.

A standout innovation in some models, like the MEDCottage, is the integration of smart health-monitoring systems. These systems track vital signs and detect changes in daily routines that might signal health issues. For example, sensors monitor a senior’s movement patterns, notifying caregivers of unusual inactivity, which could indicate a fall or other health emergency. Additionally, “ankle-level cameras,” positioned low to preserve privacy, alert family members to potential incidents without constant surveillance, offering peace of mind without compromising dignity.

Granny pods also utilize smart home technology to provide convenience and control. “Residents can use smart technology to control the temperature, door locks, and lighting with voice command,” which simplifies daily tasks and reduces the need for physical exertion in cold or dark conditions. Other useful features include automatic medication dispensers and voice-activated virtual assistants, which assist with reminders and help seniors maintain a consistent health routine without constant hands-on care from family members.

Research indicates that these tech-enabled features can enhance the mental and emotional well-being of seniors by maintaining a sense of autonomy while ensuring security. Studies have shown that when seniors can manage their environment and remain close to family, they experience reduced feelings of isolation, a common issue in traditional eldercare settings. With these accessible, tech-forward features, granny pods are reshaping eldercare by making it possible for older adults to age in place safely, right in the familiar surroundings of their own backyard.

Benefits Over Traditional Assisted Living

Granny pods offer distinct advantages over traditional assisted living, primarily due to their unique combination of independence and proximity to family, enabling a family-centered approach to elder care. One of the most compelling benefits of granny pods is the sense of privacy and independence they offer seniors without the isolation associated with long-term care facilities. Seniors can maintain their daily routines and have their own space while staying close to family, which supports their emotional well-being. Studies show that older adults who remain connected with family often experience lower rates of depression and anxiety than those in conventional care facilities. Having family nearby can be particularly reassuring for seniors who value autonomy but benefit from occasional assistance and social interaction.

From a financial perspective, granny pods can be more economical over the long term than assisted living. While granny pods require an initial investment, typically between $40,000 and $125,000, this cost is generally lower than the annual expense of assisted living facilities, which can range from $50,000 to $90,000 depending on location and level of care. Additionally, installing a granny pod may increase property value by adding functional square footage that future buyers might appreciate as a rental space or guest house.

Moreover, the ability to customize a granny pod with high-tech safety features, such as automated medication dispensers, virtual caregiving assistants, and health-monitoring systems, allows families to provide a level of personalized care that’s difficult to replicate in traditional facilities. This customization enables families to address specific needs as they arise, offering both peace of mind and flexibility as health conditions change over time. Although traditional assisted living can provide medical care around the clock, a granny pod can be adapted to include many of the same essential safety features, allowing seniors to age in place comfortably and securely.

Despite these benefits, it’s essential to consider that granny pods don’t provide the full medical support of nursing homes. If an elderly family member requires intensive medical care, supplemental in-home services may be necessary. For many, however, granny pods represent a balanced alternative that preserves dignity, privacy, and family closeness, making them an appealing choice for those who can provide intermittent support and prefer a more personal approach to elder care.

Costs and Legal Considerations

Granny pods, or ADUs, come with a significant initial investment but may provide long-term savings compared to traditional assisted living. Costs for a basic, prefabricated granny pod start around $40,000, while high-end models equipped with advanced safety and health-monitoring features can reach up to $125,000. Prefabricated models are convenient, but custom-built or renovated options, such as converting an existing garage or shed, can save $10,000–$15,000 and allow for more personalization. For families looking to offset these costs, renting out the unit once it’s no longer needed for elder care is an option in some areas, depending on local regulations.

When considering a granny pod, it’s essential to navigate local zoning laws and homeowner association (HOA) regulations, as many municipalities have specific restrictions regarding secondary structures on residential properties. Some cities require a physician’s recommendation for a granny pod to be approved as a healthcare necessity. For example, states like Virginia have passed legislation to allow temporary healthcare structures with documentation, while other states or cities have different rules for granny pods or similar ADUs. Checking with local zoning boards, HOAs, and building authorities before proceeding can help families avoid potential legal issues and ensure a smoother installation process.

In terms of return on investment, a well-placed ADU can enhance property value by 20–30%, with some units increasing value by up to 100% of their installation cost, making them a potentially valuable addition to a property. However, factors like increased property taxes and higher utility costs should be factored in, as they can impact the overall cost-effectiveness of a granny pod in the long term. For families aiming to keep loved ones nearby while providing safety and privacy, these considerations help balance the initial investment with the benefits of personalized, family-centered care.

How to Set Up a Granny Pod

To set up a functional and comfortable granny pod, start with essential accessibility and safety features tailored to support independent senior living. Begin with entryways: keep doorways and hallways wide—at least 36 inches—for easy navigation with walkers or wheelchairs. A ground-level entrance without steps or with a ramp minimizes fall risks, making the unit accessible for all abilities. Rubber or slip-resistant flooring in all rooms adds further safety, especially in high-traffic areas like the bathroom and kitchen​.

Safety features like bathroom grab bars near toilets and showers, along with a barrier-free shower, add essential stability. Automated medication dispensers with alerts can ensure timely medication management for residents. To prevent nighttime falls, consider installing lighted floorboards or low-level lighting near pathways and around the bed​.

Incorporating technology can provide an additional layer of convenience and security. Voice-activated assistants can support daily reminders, while health monitoring systems track vital signs and notify caregivers in emergencies. Advanced options include floor-level cameras that detect falls and automated controls for lighting, HVAC systems, and door locks—all accessible by remote or voice commands, simplifying day-to-day management without physical exertion​.

Lastly, for an inviting atmosphere, opt for an open floor plan to avoid obstacles, maximize natural light with large windows, and ensure a dedicated HVAC unit for easy climate control within the pod. These thoughtful design elements make the granny pod both comfortable and secure, allowing seniors to age in place with independence and peace of mind.

Embracing a New Era in Senior Living Solutions

Granny pods are transforming the way families approach eldercare, offering a practical and personalized alternative to traditional assisted living. These innovative tiny homes bridge the gap between independence and support, allowing seniors to age comfortably in close proximity to family. From high-tech safety features to thoughtful design considerations, each aspect of a granny pod contributes to a living space that is as functional as it is comforting.

For families, granny pods provide peace of mind, knowing that loved ones are nearby and have access to both privacy and assistance when needed. And with potential financial benefits, including property value appreciation and long-term savings compared to assisted living facilities, granny pods stand out as a compelling choice for family-centered, dignified eldercare. By focusing on accessibility, safety, and comfort, granny pods ensure that aging in place remains a safe and supportive experience.

(TMU) — Plastic has become the most visible pollution issue facing the world. The Great Pacific Garbage Patch, now twice the size of Texas, is the subject of many environmental cleanup efforts while plastic waste from all over the world continues to pour into our oceans at an alarming rate. Governments around the world are now debating laws restricting plastic use, with many U.S. cities and states passing bans on single-use plastic bags and straws.

As the plastic problem rages on unabated, some companies are taking it upon themselves to come up with new solutions to tackle the issue. With the passage of the 2018 U.S. Farm Bill, which legalized industrial hemp, a fresh look is being given to the versatile commodity for use in everyday items, including eco-friendly plastic. The Mind Unleashed caught up with three U.S. companies who have quietly embraced the use of hemp plastic into their business models, and their products have already hit the market.

1. Higher Hemp

Higher Hemp is a CBD dispensary that sells hemp-derived CBD products online nationwide and also offers free same-day delivery in San Diego county. They use hemp plastic packaging for many of their products including CBD flower, CBD joints and blunts, and CBD vape cartridges. Higher Hemp also uses sustainable packaging for their CBD oil and other products.

What makes Higher Hemp different from other CBD companies?

Co-founder Andrae Aldrete: “We place a lot of focus on convenience, transparency, and sustainability. Higher Hemp provides 3rd-party lab testing alongside all of the products we sell. We started out using hemp plastic for all of the products we possibly could, and we’re always looking for methods of operating where we can replace traditionally wasteful products and practices with those that are more responsibly and sustainably sourced. We seek to make CBD accessible and affordable to the masses while continuously reducing our carbon footprint by using plant-based, minimal packaging. Even the shrink wrap we use in the final sealing and packaging of our products is made from biodegradable bioplastic. We’re ok with sacrificing some aesthetic properties to prove there’s a way of doing business that’s better for our customers and the planet.”

Why does Higher Hemp use hemp plastic instead of regular plastic?

“One of the things that was non-negotiable from the start was that we weren’t going to go the traditional route of using excessive petroleum-based plastic to package our products. Hemp is the new plastic. To us, it’s unacceptable how much packaging of all types goes into even very small products in the cannabis industry and elsewhere. It’s a compounding problem both for our environment and our health when you consider that most of this plastic ends up in our oceans, polluting the food chain at every level. Considering we are selling and promoting products focused on wellness, we should also be focusing on the wellness of the planet as the health of both are correlated. 

“Luckily, when we were starting out last year, we quickly found that there were already sustainable non-plastic solutions readily available. It’s a way of doing business that we believe is simply the right thing to do. The use of plant-based plastics will be the norm in the coming years and we’re happy to be one of the companies leading the way and hopefully we’ll influence others to do the same.”

2. Sana Packaging

Sana Packaging launched the cannabis industry’s first 100% plant-based hemp plastic packaging solutions in July 2018, and in March 2019, Sana Packaging launched the cannabis industry’s first 100% reclaimed ocean plastic packaging solutions.

Why did you start Sana Packaging?

CEO and co-founder Ron Basak-Smith: “Our co-founder James Eichner and myself have lived in Colorado since 2011 and were really just disgruntled cannabis users looking at the amount of packaging waste coming from this industry. We thought we could make an impact in the cannabis space since it was such a new industry, whose norms were less developed, to create new packaging that would help move away from this disposable mindset, while creating practical products that would work for the industry.”

Do you think hemp plastic can compete with regular plastic on price/durability?

“It’s tough to compete on price because petroleum-based plastics are subsidized, but as advancements in technology continue, prices continue to drop for hemp plastic solutions. And as more companies embrace hemp and plant-based plastics, their accessibility will increase. On durability, we have to remember that we’re still at the early stages of development with hemp plastics. Just like early cars had to compete with horses, as the industry matures I believe hemp plastics will be able to compete against traditional plastic. Depending on how they’re made, yes, absolutely hemp plastics can be as strong as petroleum-based plastics. We just have to remember we’re still at the very beginning stage of development for viable plant-based plastics.”

Do you think more plastic products will be replaced by hemp in the future (such as plastic bags/straws)?

“Sana Packaging is currently focused on the cannabis industry because hemp plastic makes so much sense in this space. I think the idea here is that plant-based materials can definitely replace these products, it just depends on the consumers wanting to move forward with these options. We also have to consider our waste system because if we don’t have a way to process these plant-based products after they’ve been used, then we’re really doing an injustice to everyone and the environment.”

3. The Hemp Plastic Company

The Hemp Plastic Company produces biopolymer products made from renewable materials that are sustainable and, in some cases, compostable. Their unique process uses different hemp materials to create biopolymers that can be used in many facets of the plastics industry. They create the raw materials for manufacturers to create hemp-plastic products with.

Why did you create the Hemp Plastic Company?

Co-founder Kevin Tubbs: “It all started because a client came to me looking for hemp-based packaging for their hemp products. I have a background in developing eco-packaging and thought making packaging out of previously unusable hemp waste was a great idea. One client led to another, and suddenly people from all over the world became interested in what we were doing.”

Are you seeing demand rising?

“We’ve had a huge number of new customers looking for solutions in hemp plastic, and our customers are coming up with many new use-cases all the time. We supply the raw materials and customers are finding new uses to mold our hemp plastic into. We now have a library of fine hemp plastics including propylene, ethylene, ABS, and PLA.”

Where do you see the hemp plastic industry going?

“We’ve reduced plastic pollution down to a design decision. Designers need to buy into the idea of using hemp plastic and take another look at their designs to make sure they’re easy to degrade. Imagine Legos being made from hemp ABS! Consumers are also starting to think about packaging beyond single-use and what these containers can be re-used for after they’ve served their initial purpose. Some new products I’m excited about are hemp-based films we’re developing that could provide renewable options even for leather, and degrade 100% back into plant material.”
