The United States has played a unique role in the history of conservation. At times, it has been seen as an obstacle to global environmental progress—resisting international climate agreements, rolling back protections, and allowing denial to stall urgent action. But just as often, it has led the world—pioneering national parks, shaping international treaties, and inspiring movements through art, activism, and philanthropy. American scientists have uncovered the dangers of pollution, American leaders have signed groundbreaking environmental laws, American philanthropists have funded conservation on a massive scale, and American citizens have marched, organized, and demanded change. Today, as we face new environmental challenges, it’s crucial to step back and see the bigger picture. History shows us that progress is possible—and that when Americans rise to the occasion, we don’t just change our country. We change the world.
“The battle for conservation must go on endlessly. It is part of the universal warfare between right and wrong.” - John Muir

The story of American conservation began with a bold idea: that nature, in all its beauty and grandeur, should belong to the people and be preserved for future generations. In 1872, the United States created Yellowstone National Park, the first of its kind in the world. This revolutionary act not only safeguarded a vast and breathtaking landscape but also set a precedent for conservation efforts across the globe. It was the first step in a long journey—one that would lead to the establishment of national parks, wildlife refuges, and environmental protections that continue to shape the world today.
From the creation of the National Park Service in 1916 to the passage of the Clean Air and Clean Water Acts in the 1970s, the U.S. has been at the forefront of efforts to protect the environment. The fight to ban DDT, the success of the Montreal Protocol, and the global impact of Earth Day—first organized in the U.S. in 1970—are just a few milestones in a long history of environmental progress.
“We have fallen heirs to the most glorious heritage a people ever received, and each one must do his part if we wish to show that the nation is worthy of its good fortune.” - Theodore Roosevelt
"Clean air, clean water, open spaces - these should once again be the birthright of every American." - Richard M. Nixon

Yet, no single list could ever capture the full scope of these achievements, nor the countless individuals who have dedicated their lives to conservation. Scientists, activists, philanthropists, and everyday citizens—in the U.S. and around the world—have worked tirelessly to protect the planet, often against great odds. Their efforts, whether in the halls of government, the depths of the oceans, or the pages of a book, have shaped the way we understand and care for our natural world.
Today, our partners at Jocotoco are not only protecting existing wilderness but also achieving an ambitious goal: rewilding Floreana Island in the Galápagos. By restoring ecosystems and reversing 200 years of ecological damage, they are setting a powerful example of what conservation can accomplish.
Environmentalism is not bound by time or borders. The passion of one generation inspires the next, and the actions of individuals ripple outward, creating a force for change that stretches across continents. Just as Rachel Carson’s warnings about pesticides ignited a movement, just as American conservationists helped establish the first global environmental treaties, the work we do today will inspire those who come after us. The story of conservation is still being written—and we each have a role to play.

The pursuit of science and truth can create a false sense of optimism—the belief that because truth reflects reality, it will inevitably prevail. And in one sense, it will: climate change is not a matter of debate, but a fact that is already reshaping our world. But will truth prevail where it matters most—in the consciousness of people, in our institutions, in the decisions that shape the future? The fight against climate change has made it painfully clear that we cannot take this for granted.
Unprecedented wildfires tear through forests and communities. Drought strikes even the rainforests. Coral bleaching ravages fragile marine ecosystems. Species are vanishing at catastrophic rates, and entire ecosystems are being pushed to the brink of collapse. This is the painful and undeniable reality—yet half of Americans refuse to accept the science. They continue to vote for leaders who shape domestic and international policies based on denial and misinformation. Despite the tireless efforts of scientists, activists, journalists, and policymakers, climate denial remains deeply entrenched.
Environmental protection is, without question, one of the most urgent challenges facing humanity—but we are not confronting it as a united front. Instead, the fight for the planet is waged in countless, scattered battles: scientists racing to document vanishing species, activists working to reclaim their institutions, Indigenous communities defending their land and culture against destruction.
“The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.” - Rachel Carson

On the frontlines of deforestation, the Kayapo people are safeguarding over 9 million hectares of rainforest. Their decades-long success stands as proof of the power of Indigenous knowledge, sustained philanthropy, and strong institutions. Despite political challenges and external pressures, the Kayapó have remained resilient—demonstrating that sustained support and institution-building are key to long-term conservation.

Even in times of division and isolationism, there is strength in connection. Across borders and disciplines, across movements and generations, we are part of a vast and interwoven network of people fighting for nature. In this web of defenders—scientists, advocates, land stewards, and educators—our power lies in learning from one another, supporting each other, and standing together. The work ahead will not be easy, but it is shared. And together, we can push forward.
Despite the challenges we face, there is good news: the network of individuals fighting for conservation is real, and it is stronger than ever. Across the globe, people have been building knowledge, protecting ecosystems, and defending biodiversity. Indigenous communities have not only safeguarded their lands but have also built institutions to ensure their voices are heard. Scientists and conservationists have spent decades exchanging knowledge, expanding our understanding of species and ecosystems, and developing solutions that will guide us forward.
In this era of political uncertainty and geopolitical instability, we must do everything in our power to maintain and strengthen these connections. Conservation has always been a collective effort, and the institutions that support it—whether scientific, governmental, or grassroots—are more important than ever. The International Conservation Fund is privileged to work alongside incredible partners around the world, many of whom face great challenges and uncertainty. But we remain committed to this work, to them, and to building upon the hard-won achievements of those who came before us.
There are thousands of conservation projects around the world that go unnoticed and millions of individuals holding invaluable knowledge and skills—each representing a piece of a puzzle we must solve together. The pieces fit; we just need to connect them, strengthen them, and ensure they endure. Take a moment to explore the partners that ICF supports. Learn about their projects, amplify their work, and contribute to conservation efforts that will leave a lasting impact—one that ripples across generations and ecosystems.
The future of conservation is still being written, and it is up to us to ensure that this legacy not only endures—but grows.
