This week, four astronauts aboard the Artemis II Orion spacecraft achieved something humanity has not done in over fifty years. They flew around the far side of the moon, traveling farther from Earth than any humans in history – 252,760 miles. As they passed behind the lunar surface, they turned their cameras back toward home and captured a breathtaking Earthset, watching our bright blue planet sink behind the desolate, cratered edge of the moon. Looking at all of the media coming from the mission gives me chills in the best way.

The Cognitive Shift
When astronauts view our planet from this immense distance, they often experience a profound cognitive shift known as the Overview Effect. From 250,000 miles away, they can’t see political borders, neighborhood disputes, or ideological divides. They see a single, fragile ecosystem. They realize that every being, be they a person, animal, or plant, shares the same life support system and collectively, the same destiny. We all only have one home and it belongs to all of us.

A Floating Laboratory for a Sustainable Earth
People frequently wonder why we invest in space exploration when we face so many massive challenges right here on Earth. The answer is that a deep space capsule is the ultimate testbed for our future. We do not explore space to abandon our home planet; we explore space to discover the exact tools necessary to protect it.

To survive a lunar mission, astronauts cannot waste a single resource and a vast group of people with different talents and experiences must work together as a cohesive team with a singular shared mission – bring them all home safely. They must operate a circular economy. NASA engineers design advanced filters to scrub carbon dioxide directly out of the cabin air—technology that now forms the foundation of direct air capture facilities fighting global warming today. They develop systems to recover and purify every drop of moisture, translating directly to water filtration for drought-stricken communities. They conduct experiments on high-yield indoor agriculture to feed the crew without the benefits of direct sunlight or nutrient-rich soil, helping us understand how we can grow food in harsh environments. Staging this mission also requires the development of stronger, lighter materials that translates into the conservation of valuable resources.

Alongside this climate engineering, the Artemis II crew is conducting experiments that directly advance medical science. They carry microchips containing living human bone marrow tissue to study exactly how deep-space radiation and microgravity affects human cells. They monitor their own biological responses to understand why and how extreme stress alters the human immune system. Solving these medical challenges in space paves the way for individualized cancer treatments, tools to predict and treat chronic conditions, and advanced healthcare innovations that test drugs and vaccines. All of this research means that the astronauts are both scientists and test subjects. What we learn from these missions directly translates to helping all of us build a better healthcare system.

Orchestration on a Massive Scale
The mission also represents the ultimate example of community orchestration. Sending a crew around the moon and safely bringing them back is never the work of one isolated visionary. It requires a massive, synchronized ecosystem of engineers, technicians, and scientists across the globe. Thousands of people must set aside their individual egos and operate with absolute trust in one another to navigate the unknown.

The Takeaway
We do not need to launch into orbit to apply the Overview Effect to our daily lives. When we get stuck in the weeds of local disputes or feel overwhelmed by the friction of community building, we simply need to change our vantage point.

We can actively choose to step back and look at our neighborhoods as unified ecosystems.

  • Change your altitude to change your attitude: When a conflict arises in your community, intentionally zoom out. Ask yourself how this specific disagreement affects the overall health of the neighborhood ecosystem rather than just your immediate block. Then help other people zoom out as well to gain the same benefits of perspective.
  • Acknowledge the shared ship and the shared journey: Remind yourself and your neighbors that you all rely on the same local infrastructure and green spaces, and that collectively you are building your local economy to benefit everyone. You succeed or fail together.
  • Orchestrate across borders: Look for ways to connect your local initiatives with efforts in neighboring communities. A thriving garden in your neighborhood benefits the pollinators across your city and beyond.
  • Translate the research: Take inspiration from the Artemis crew. Look for ways to do small experiments and use the solutions you develop through those experiments to help your community and share with adjacent communities.

Nature requires us to act as a unified whole. We just need the right perspective to see it. Luckily for us, the crew of Artemis II is helping all of us to keep looking up.

Digging Deep: How Healthy Soil Can Help Heal Our Planet

We often look to the skies, the oceans, or technological innovations when discussing climate change solutions. But what if a powerful tool lies right beneath our feet? Healthy, living soil is an unsung hero in the fight against climate change and a cornerstone of a truly healthier planet.

To educate myself on soil health, I watched the documentaries Kiss the Ground and Common Ground on Amazon Prime Video. After watching them, I immediately visited their resources website filled with free ebooks and guides that can help all of us advocate for this climate solution and immediately take action in our everyday lives.

For too long, we’ve treated soil like dirt – an inert medium to hold plants up. In reality, healthy soil is a complex, dynamic ecosystem teeming with billions of microbes, fungi, insects, and worms. This underground world plays a crucial role in regulating our climate and supporting life on Earth.

How Does Soil Fight Climate Change? The Carbon Connection

The key lies in carbon sequestration. Here’s how it works:

  1. Photosynthesis: Plants pull carbon dioxide (CO2​), a major greenhouse gas, from the atmosphere.
  2. Carbon Transfer: Through photosynthesis, plants convert this carbon into sugars to fuel their growth. Some of this carbon builds their leaves and stems, but a significant amount is channeled down into their roots.
  3. Soil Storage: Plants release carbon compounds through their roots (exudates) to feed soil microbes. When plants and microbes die and decompose, this carbon becomes part of soil organic matter (SOM) – a complex, dark material rich in carbon.
  4. Locking it Away: In healthy, undisturbed soil with a thriving microbial community, this carbon can remain stable and locked away for decades, centuries, or even millennia, effectively removing it from the atmosphere where it would otherwise trap heat.

The Problem with Degraded Soil

Unfortunately, many modern agricultural and land management practices have degraded our soils worldwide. Practices like intensive tilling, overuse of synthetic fertilizers and pesticides, deforestation, and leaving soil bare disrupt the soil structure, kill beneficial microbes, and lead to erosion.

When soil is degraded:

  • It loses its ability to store carbon. Tilling, for instance, exposes SOM to oxygen, causing microbes to rapidly consume it and release the stored carbon back into the atmosphere as CO2​.
  • It can release other potent greenhouse gases like nitrous oxide (N2​O) due to synthetic nitrogen fertilizer overuse.
  • Its capacity to absorb and hold water diminishes, increasing runoff, erosion, and vulnerability to both droughts and floods.

Beyond Carbon: The Ripple Effects of Healthy Soil

Improving soil health isn’t just about carbon. It creates a cascade of benefits for a healthier planet:

  • Improved Water Management: Healthy soil with good structure absorbs more water, reducing runoff, preventing erosion, and recharging groundwater. This makes landscapes more resilient to both floods and droughts.
  • Enhanced Biodiversity: Thriving soil ecosystems support a vast array of life, from microscopic bacteria and fungi to earthworms and insects, forming the base of terrestrial food webs.
  • Reduced Pollution: Healthy soil filters water and can break down certain pollutants. By reducing the need for synthetic fertilizers and pesticides, soil-friendly practices also decrease chemical runoff into waterways.
  • Increased Food Security & Nutrition: Healthy soils produce more resilient and nutrient-dense crops, contributing to a more stable and nutritious food supply.
  • Reduced Need for Inputs: Soils rich in organic matter and microbial life naturally provide more nutrients to plants, lessening the dependence on synthetic fertilizers, the production of which is energy-intensive and contributes to greenhouse gas emissions.
  • Reduced Erosion: Strong soil structure, held together by roots and microbial glues, resists being washed or blown away, preserving our precious topsoil.
  • Cleaner Air: By reducing wind erosion, healthy soils contribute to cleaner air with less dust and particulate matter.

How Can We Improve Soil Health?

The good news is that we know how to regenerate soil health. These key practices, often grouped under the umbrella of regenerative agriculture or soil health management systems, have proven benefits for soil health:

  • Minimize Soil Disturbance: Reducing or eliminating tillage (plowing) keeps the soil structure intact, protects soil organisms, and prevents carbon release.
  • Keep the Soil Covered: Planting cover crops or leaving crop residue on the surface protects the soil from erosion, suppresses weeds, and adds organic matter.
  • Increase Plant Diversity: Rotating diverse crops and integrating cover crops feeds different types of soil microbes and improves soil structure.
  • Keep Living Roots in the Ground: Continuous plant cover ensures the soil microbiome is consistently fed via root exudates.
  • Integrate Livestock (Managed Grazing): Well-managed grazing can stimulate plant growth, add manure (nutrients and organic matter), and improve soil health.
  • Reduce/Eliminate Synthetic Inputs: Minimizing chemical fertilizers and pesticides allows the natural soil ecosystem to thrive.
  • Composting: Adding compost to gardens and farms directly increases soil organic matter.

What Can You Do?

  • Support Regenerative Farmers: Look for food grown using soil-healthy practices. Ask questions at farmers’ markets.
  • Compost: Turn your food scraps and yard waste into valuable soil amendments for your garden or community garden.
  • Garden Smarter: Practice no-dig gardening, use mulch, plant cover crops, and avoid synthetic chemicals.
  • Advocate: Support policies that incentivize farmers to adopt soil-healthy practices.
  • Learn & Share: Learn more and spread the word about the critical importance of soil health. Watching Kiss the Ground and Common Ground on Amazon Prime Video, and visiting their resources website are great ways to start!

Conclusion

Healing our planet requires looking down as much as we look up. By focusing on regenerating the health of our soils, we can actively draw down atmospheric carbon, enhance water cycles, boost biodiversity, improve food security, and build resilience to climate extremes. Healthy soil is a powerful, natural climate solution hiding in plain sight – it’s time we recognized its potential and started digging deep for a healthier future.

Minnesota Governor Tim Walz has spent the better part of the last decade instituting climate policies that make economic sense and help all Minnesota residents live healthier, happier lives. Let’s dive into what he’s done in Minnesota and how this could help the entire country. 

1.) Minnesota is a clean energy leader

Like many states, Minnesota was long powered by coal. Today, 50% of the state’s power comes from wind, solar, and nuclear power, thanks to Walz. It’s one of the fastest transitioning states in the country. In 2023, he signed the Minnesota Clean Energy Bill into law, ensuring Minnesota is fossil fuel-free by 2040. (If you want to see how all U.S. states stack up with their energy sources, check out this cool interactive created by Nadja Popovich.) 

2.) Minnesota is a climate policy leader

On Walz’s watch in 2022, Minnesota launched the Climate Action Framework. This plan is preparing the state for climate change impacts, taking immediate and near-term actions to make the state “carbon-neutral, resilient, and equitable.” To-date, this plan has prompted the Minnesota Legislature to approve over 40 climate initiatives across industries including energy, health, agriculture, construction, and transportation. 

3.) Minnesota policies connect everyday local concerns with climate solutions 

Minnesotans have acutely felt the impacts of climate change over the past 5 years — drought caused economic losses for farmers and ranchers, wildfire smoke inundated cities and towns leading to health challenges, and a lack of snow and ice caused economic losses in the fishing and winter tourism industries. The state’s climate policies focus on climate solutions that create jobs, protect land and water vital for farmers and ranchers, reduce energy costs for consumers, and improve air quality to improve the health of residents, particularly children, the elderly, and those with existing health conditions. 

Walz’s simple, straightforward, optimistic, and solution-oriented communication style unites people, makes them feel hopeful, and connects the challenges they face with policy solutions that will directly solve those challenges. This makes him wildly popular with constituents across the political spectrum. People trust him because he’s helping them. This has helped turn Minnesota into a climate action powerhouse. Using his playbook, we could do this for the entire country.
