A World Tour of Action on Earth Day

Each year, Earth Day invites reflection on the state of our planet, and on the role we each play in shaping its future. The 2026 theme, Our Power, Our Planet, emphasizes collective action: the idea that meaningful change emerges not from a single decision or institution, but from the accumulation of efforts across communities, regions, and systems.

While environmental challenges often dominate headlines, solutions are being implemented, initiatives are taking root, and their impact is already becoming visible.

Across the continents, we looked for tangible movements aligned with the spirit of Earth Day, from local initiatives to broader transformations. This article highlights one example, among many others, per continent, offering a journey around the world through signals of progress already underway.

In parts of Kenya, reforestation is taking on inventive and adaptable forms. At the core of this approach are small seedballs, simple in appearance yet carefully designed, containing indigenous seeds wrapped in a mix of charcoal dust, soil, and nutrients.

In Nairobi alone, an estimated 750,000 kilograms of charcoal are consumed daily, with around 15% ending up as dust and fragments. Rather than being discarded, this material is now repurposed. The charcoal coating protects the seeds from animals, retains moisture, and supports early growth, gradually breaking down with the rains to enable germination.

Seeds are dispersed by hand, on camelback, and even from the air, sometimes becoming a game in schools, where children throw seedballs across open land. Produced at scale – with some operations distributing up to 20,000 seedballs per day – this approach combines ecological knowledge with resource efficiency, turning urban waste into a tool for regeneration.

In Colombia, restoration takes the form of careful preservation and propagation.
In the mountains above Medellín, Daniel Piedrahíta is building a “Noah’s Ark” for orchids. 

Once a hobbyist grower, he now leads seed-sharing initiatives across Latin America, working with communities to reintroduce native species in areas affected by deforestation, wildfires, and illegal harvesting.

At Alma del Bosque, a vast greenhouse housing more than 25,000 plants, rare orchids are cloned and propagated – their microscopic seeds produced by the millions to ensure their survival.

Daniel is one of the National Geographic 33, a recognition awarded to individuals driving meaningful change around the world.

Together, these efforts reflect two complementary approaches: planting for the future, and safeguarding what remains.

Parks Canada has announced that “bison now roam free in Banff National Park. After an absence of over a century, the return of wild plains bison is a historic, ecological and cultural triumph.”

Across North America, restoration efforts are increasingly focused on entire ecosystems rather than isolated interventions. The reintroduction of species such as the American bison is helping restore ecological balance across vast landscapes. Once brought to the brink of extinction, bison populations are now gradually recovering through conservation programs, often led in collaboration with Indigenous communities.

In the Rocky Mountains, 16 plains bison were reintroduced in 2017; by 2024, the population had grown to over 130. At a broader scale, since 2020, initiatives led by organizations such as The Nature Conservancy and InterTribal Buffalo Council have returned nearly 3,000 buffalo to Native Nations, restoring them to their ancestral lands. This large-scale effort – significantly expanded in recent years – marks the largest buffalo restoration in history.

Beyond the species itself, their return reshapes the land, supporting vegetation, improving soil health, and enhancing biodiversity. These initiatives reflect a broader understanding: restoring nature is not only about individual species, but about rebuilding the systems that sustain them.

Across parts of Oceania, restoration efforts are focusing on the interface between land and sea.
In coastal regions of Australia, mangrove ecosystems are being replanted and protected – not only to restore biodiversity, but also to stabilize shorelines and capture significant amounts of carbon.
Often referred to as “blue carbon” ecosystems, mangroves store carbon at rates far higher than many terrestrial forests, while also providing natural protection against erosion and extreme weather.

These initiatives highlight the interconnected nature of environmental systems, where restoring a single ecosystem can generate multiple benefits, for climate, biodiversity, and local communities alike.

Across Europe, the energy transition is no longer a distant ambition, it is unfolding in real time. What was once considered alternative has become foundational.

Wind and solar have now overtaken fossil fuels as primary sources of electricity. In 2025, 47.3% of Europe’s electricity was generated from renewable energy, with Denmark, Austria, and Portugal among the leading contributors.

At a continental scale, this marks a structural turning point, one that reflects how even large, complex systems can evolve, and how the transition toward cleaner energy is no longer a projection, but a reality already taking shape.

As part of this global tour of Earth Day initiatives, Asia offers a glimpse into the power of emerging leadership. In 2026, the United Nations Development Program launched its Climate Catalysts program, supporting young innovators across the Asia-Pacific region who are developing practical, locally grounded solutions to environmental challenges. From adaptation strategies to low-carbon innovations, these initiatives reflect a shift toward action rooted in lived experience. By equipping a new generation with tools, mentorship, and visibility, the program highlights how meaningful change is increasingly driven from the ground up, where local insight meets global urgency

Taken together, these efforts – from local initiatives to international agreements – point toward a broader shift in how environmental challenges are being addressed. In some cases, the results of this collective approach are already visible.

High above the Earth’s surface, one of the clearest indicators is the recovery of the ozone layer. Following decades of coordinated global action under the Montreal Protocol, the atmosphere is gradually healing. According to some estimates, it could return to 1980 levels as early as 2040.

It stands as a rare and powerful example: when efforts align across borders, sectors, and societies, change can extend far beyond its point of origin, reaching even the atmosphere itself.

From scattered seeds in Kenya to restored ecosystems in North America, from energy transitions in Europe to emerging climate leadership in Asia, these stories reflect different scales and approaches, yet they are not isolated.
They form part of a broader movement, shaped by countless decisions, actions, and collaborations. Progress is not always immediate, nor evenly distributed, but it is present.

Taken together, these efforts begin to reveal a direction, one that suggests that change, while complex, is already underway. Not everything is resolved. But not everything is broken. And something is shifting.
