Billionaire Family Members to Receive Hand-Delivered Message from the Amazon

This nationwide tour comes on the heels of the unveiling of a massive 11 story, 15,000+ square foot mural in São Paulo, Brazil, which has already caught the attention of the New York Times. Created by globally renowned Brazilian artist-activist Mundano, the mural was crafted using the literal ashes of forests across South America—forests burned to make way for commodities traded by Cargill. This powerful artwork demands that the Cargill-MacMillan family honor their 2025 commitment to eliminate deforestation from their supply chains.

The stakes have never been higher. This summer has witnessed one of South America’s worst wildfire seasons in history. The vast majority of these fires are no accident—they are set intentionally to clear land for plantations that benefit corporations like Cargill. This ongoing environmental catastrophe threatens the worlds most important landscapes and the homes of Indigenous peoples.

The Cargill-MacMillan family, who own 90% of Cargill, Inc., the largest private company in the U.S. and the world’s largest agriculture corporation, are no strangers to profit at any cost. Cargill is infamous for its role in deforestation, Indigenous displacement, child labor, slavery, and other gross environmental and human rights abuses. With a combined family fortune exceeding $60 billion, they are the wealthiest family in America and have more billionaires within their ranks than any other family on Earth. And yet, they continue to turn a blind eye to the destruction their business empire fuels.

But this time, they won’t be able to ignore the message. Hand-delivered by Mathew Jacobson, these messages from the Indigenous peoples of Brazil are written in the ashes of the very forests Cargill has helped destroy. The message, penned by the Munduruku people of Sawré Muybu, is clear and direct: “Keep Your Promise. Stop the Destruction.” It calls on the Cargill-MacMillan family by name, demanding that they stand by their commitment to end deforestation. Twenty organizations have signed a letter urging the family to end Cargill’s legacy of human rights abuses and environmental destruction throughout its supply chain.

The crimes against South America’s ecosystems do not end with plantations. Cargill is also a driving force behind the proposed construction of the Ferrogrão mega-railway, which would carve a destructive path through over 600 miles of the Amazon rainforest. This railway would slice through Indigenous lands, conservation areas, and the homes of isolated tribes who have never been consulted. The projected toll: half a million acres of deforestation. All for the sake of feeding factory farms in China and Europe, while Brazil’s natural resources and Indigenous homes are sacrificed for corporate greed.

The message from Brazil’s Indigenous leaders is simple: Cargill, it’s time to stop. South America’s future—and the future of our planet—cannot be traded for short-term profits. The Cargill-MacMillan family must take responsibility and act before it’s too late. The time to end deforestation is now.
