Brazil's Amazon deforestation fell to 3,335 square kilometres in the past year — the lowest since satellite monitoring began in 1988, and 41.8% below the prior year. The previous record was beaten by 1,236 sq km, an area the size of Rio de Janeiro. Since Lula took office in 2022, the rate has dropped 71.2%, driven by enforcement funding and restored environmental agencies. The neighbouring Cerrado savanna hit its own low since 2001, down 48.4% over four years. These are not marginal gains. They represent the most successful large-scale deforestation reversal on the planet. The problem is that every mechanism behind this success is reversible by executive action. Lula's predecessor Jair Bolsonaro oversaw a 59.5% increase in Amazon deforestation between 2019 and 2023 — roughly a million trees destroyed per day — by gutting enforcement budgets, reducing penalties, and openly encouraging illegal miners, loggers, and land grabbers. His son Flávio, now in the presidential run-off against Lula on 25 October, has followed the same playbook: courting extractivist landowners, ignoring climate in his manifesto, and promising to free his convicted father and install him in government. The electoral geography tells the structural story. Bolsonaro won votes near degraded forest, mines, ranches, and soy monocultures. Lula's support concentrated in cities and areas of intact vegetation. This is not a culture war — it is a map of who profits from destruction and who doesn't. The geopolitical overlay makes it worse. The Bolsonaro family has cultivated deep ties to the Trump administration. Eduardo Bolsonaro lives in Texas and has publicly called for US punitive tariffs against Brazil. Jair has saluted the US flag and led "USA, USA" chants. A Bolsonaro presidency is expected to redirect Brazil's trade priorities — particularly critical minerals — from China and Europe to the US. The Amazon becomes a bargaining chip in great-power resource competition. Lula frames the Amazon as sovereign Brazilian territory, an Indigenous homeland, and a global climate asset. The Bolsonaro vision treats it as an extractable resource to be sold to the highest bidder. Former environment minister Marina Silva has warned that Flávio Bolsonaro will attempt to finish his father's "perverse project" to destroy the Amazon. The states with the worst deforestation records — Pará (33.9% of all Amazon clearance), Mato Grosso (25.5%), and Amazonas (15.7%) — still improved by over 45% year-on-year under Lula. The one state where deforestation increased, Roraima (up 0.4%), is a Bolsonaro stronghold. The correlation between political alignment and forest destruction is not subtle. Marcio Astrini of the Climate Observatory captured the stakes plainly: "The country will decide whether we move toward the end of deforestation or toward the end of the forest." This is not hyperbole. The data shows both trajectories are achievable. The question is which government holds the chainsaw.
