Brazil has committed to ambitious goals, including the reforestation of 12 million hectares (1). However, a recent proposal by Brazil’s Congress (2, 3) puts at risk the Atlantic Forest, one of the world’s most threatened biomes (4). The Provisional Measure (MP) 1150/2022 aims to change the Atlantic Forest Law (11.428/2006) and the Forest Code (12.651/2012) by loosening restrictions on removing native vegetation. After Brazil’s Chamber of Deputies and Senate approved the proposal in May, President Lula rejected it, but the Congress could overturn the presidential veto. National and international pressure are essential to persuade Brazil’s Congress to comply with the presidential veto and prevent further attacks to the Atlantic Forest.
