Are We Running Out of Clean Water?

The first line in this TED-ED video is: "From space, our planet appears to be more ocean than earth." 

We were reminded of this with some of the amazing pictures that came out from Artemis II's mission on April 1st to 11th, 2026.

Yet, water scarcity is real for many people globally. Accessibility of this water is our biggest issue, for where it is located versus where it is needed.

Watch TED-ED's "Are We Running Out of Clean Water" to learn more. Additionally, use the TED-ED's resources for both quizzing yourself and your students as well as their lesson prompts and plan.

The Four Winds of Change: Connecting the 1930s Dust Bowl & the 2020 Pandemic

A few months ago I listened to the audio book The Four Winds: A Novel by Kristin Hannah. It details the ten-year time period during the Depression and 1930s of the American Dust Bowl. Devastation hit farmers as drought and years of poor farming protocols let the topsoil to just literally go "flying in the wind." Kansas, Colorado, Oklahoma, Texas, and New Mexico all felt the ravaging devastation of this environmental crisis.

Having grown up in the Midwest, I know of those flat lands. Those farmlands. Perhaps that is why I was haunted by this book. I'm sure Kristin Hannah's powerful storytelling ability was also at play. She has a remarkable way of creating characters who rise through the resilience during hardship.

I also was struck by the similarities I noticed on the human impact of both the Dust Bowl (a major environmental issue nearly a century ago) and the COVID-19 pandemic (just 6 years ago in 2020): 
  • There was economic fallout as people lost their jobs. Likewise, the ability to find and finance food was an issue due to supply and demand and availability issues, not to mention the logistical issues of transporting food. 
  • Governmentally, policies needed to be shifted or newly put into place. This often came in both situations with push back and concerns.
  • There were health, physical, and medical ramifications as as the air around us had the capability of making people ill. People needed to wear masks (or wet bandanas) to assist with breathing during the "black blizzards" of the Dust Bowl, just as we had to wear masks to protect ourselves from the germs of the virus in 2020. "Dust pneumonia" was a medical side effect based on the poor air quality of dust-filled air in the 1930s. Both epidemics resulted in respiratory health issues. Both epidemics resulted in thousands of people losing their lives. Both were certainly a time of a lot of stress.
  • Socially, people were impacted in many ways, based on their decisions on how best to stay safe. Community gatherings couldn't happen in the same ways as before. This included schooling. Isolation was an issue. At times in both situations, people may have needed to move due to their circumstances. 
  • Prejudice too was a parallel issue during both historic events: the "Okies" on the move to find work during the Depression were greatly looked down upon. Depending on your political slant during the COVID pandemic, you could get grief from friends, family, or neighbors based on how cautious you were or were not: Did you wear a mask? Did you wear it well or haphazardly? Did you scoff at the vaccine and the science that shifted as people learned more? The government leaders chose to make it a political, divisive issue, which created additional grief. 
From an agricultural sense, we have done a lot since the 1930s to farm smarter to maintain soil health over time. Purposely planting windbreaks and cover crops, promoting contour plowing, reducing over-tillage, and improving soil's water retention has made for a healthier culture of agriculture. But we can also see where if funding is reduced in any of these areas or if people use poor farming procedures, we can fall victim to Mother Nature when the rain ceases to fall. Droughts happen. Wind happens. Heat waves happen. Because of all of that, we need to be proactive with environmental policies. Climate change has significantly intensified all of that, and sadly the environment over the last decade or more has become political. 

Sitting here, nearly a century beyond the Dust Bowl, Kristin Hannah's The Four Winds reminds us that history’s lessons are never far behind. Environmental crises (whether dust storms or global pandemics) share a common truth: resilience begins when communities pull together and adapt with empathy, foresight, and innovation. Kristin Hannah's story and the insights we all gleaned in 2020 show us the importance of taking care of each other, honoring science, adapting as needed with resilience. These are some of the same essential traits we need to tackle global issues like climate change, biodiversity, food insecurity, pollution, environmental injustice and more.

Floating Farms Follow-Up: Build Your Own

While building the interactive for my previous post in Canva Code, I decided to play around with the concept of creating another interactive where you could build your own floating farm. I thought this could be a great way to put sustainability & STEM thinking into action, inviting users to combine resource management mentality along with the ever-real factor of economics in order to figure out some design trade-offs. That's what innovation is all about!

So "diving in," let's get our "feet wet" and get to action building a farm of the future:

💠 Imagine you're the lead designer, with your next project being to create a floating farm. 

💠 Your job: Create a sustainable agriculture system on the water, within budget. 

💠 Your budget: $100,000.

💠 What will you prioritize? Solar panels? Hydroponic beds? Livestock pens? Community learning spaces? Everything comes with both a price tag and a purpose. Where will your eco-choices lead you? What floating farm will you build?

Floating Farms: A New Green Frontier


More and more, climate change and population growth are impacting everything. Including traditional agriculture.

What if the future of farming isn't on land? What if our blue planet could help us out by maximizing our waterways to help create "floating farms?" 

It's a revolutionary concept that the Netherlands have used, along with a growing number of other communities. It is helping to "turn the tide" on how we grow food. 

Floating farms are a type of agricutural system built on a floating platform designed to operate on rivers, lakes, harbors, and coastal zones. Think of it as a large scale garden on a raft. These farms often build in eco-friendly systems like hydroponics, solar energy, and use recycled water. This makes them for a closed-loop system. Additionally, it makes them well-suited for urban environments with limited space. It's a way to maximize resources and sustainability when space is at a premium. 

Floating farms help adapt to the negative effects of climate change by contending against future flooding from rising sea levels (because a floating farm would rise as the water rises). It also positions food closer to urban areas, which helps not only bring fresher food to cities but also reduces the need for transport. The alternative energy sources they use also reduce the reliance on fossil fuels, which ultimately conserves resources. This, in turn, also can aid in drought-proofing the farm due to the water reserves floating farms factor in.

Netherland's Rotterdam’s Floating Farm is a pioneer in floating farms. There they have a three-level platform complete with solar panels, rainwater collection, and robotic milking systems for their cows. As they would say, it's a mindset-shift: a "transfarmation." Check out this video (or visit their website) to learn more. (I love how they refer to the UN Sustainable Development Goals on their website. As they say on their website: "At Floating Farm we have an eye on the future, for everyone.")

Floating farms offer a wealth of eco-advantages: 
  • Minimizing land use: They free up valuable land for conservation or urban development.
  • Maximizing flooding resilience: This plays out especially in coastal cities where sea levels are rising. 
  • Integrating renewable energy resources: Wind turbines and solar panels can efficiently power this farming grid.
  • Employing circular systems: Waste is composted and put back to use.
  • Serving as educational opportunities: They are learning labs of sustainability, science, and engineering in action.
Of course, as with anything (including innovative problem solving), challenges exist:
  • The initial cost can be quite high.
  • They can impact the aquatic ecosystem on which they are built.
  • Over time, degradation happens, which can create new problems to solve.
Innovation has always depended on forging new frontiers. This could be a new foray into future thinking, serving as a way that combats the issues that traditional farming is experiencing. With luck, science, skill, and design, perhaps these floating farming platforms bobbing on the water take us one step closer to a morre sustainable and adaptable world.

The Symbiosis of Agrivoltaics

Today's post is brought to you by Environmental Math. Why? Because there's a high usage of "+" and "=" ahead to land on environmental science.

Here's the breakdown:

  • Agrivoltaics = “agriculture” + “photovoltaics” = where the same land is used for both agricultural reasons and solar energy
  • Photovoltaics = solar powered technology
  • Symbiosis = an interactive relationship between 2 species (typically, but not always beneficial to both)  
    • Examples:
      • Bees and flowers = pollination + nectar
      • Clownfish and sea anemones = protection + cleaning
      • Oxpeckers birds and large mammals (ex: rhinos & zebras) = tick and parasite eating + tick and parasite removal 
      • Acacia trees and ants = tree thorns protect the tree + provide shelter/feed the ants

  • Mutualism = A form of symbiosis where 2 species benefit off each other

Given all of the above, here's this math:

Agrivoltaics = symbiosis = win + win

This image is a great example of the win, win of the symbiotic relationship between humans, land, and livestock:

Check out how the land is being used in a multitude of ways: grazing grass, growing crops, housing solar panels for generating energy which, in turn, have the panels creating shade for the animals. 

Additionally...

  • The shade can also reduce water loss from the land. This, in turn, helps grow and support plants (the food source for animals) while simultaneously creating less need for irrigation.
  • Overall soil moisture helps increase biodiversity on the land. 
  • As the sheep, goats, cows, etc graze the land, the grass is kept trimmed, reducing the need to mow.
It showcases a sharing of the land versus a competition on how to use the land. It provides a man-made version of symbiosis and mutualism. It's teamwork at its finest. Win, win, win!

Playing around with my new best friend, Canva Code, I created this upper elementary/middle school level interactive which can further help the concepts of agrivoltaics sink in. To go directly to the site to see it screen-sized or to link to it in your own classroom, click here.
