Vast soy monoculture abuts the remnant Amazon rainforest near Santarém, Pará, Brazil, where a newly cut access road slices through primary forest. Agricultural expansion for global commodity markets is driving deforestation, environmental degradation and the isolation—and eventual loss—of venerable Brazil-nut trees once integral to rainforest ecology. Conservationists warn that such land‑use change undermines biodiversity, carbon storage and the livelihoods of traditional communities.
