During the closing ceremony of the Terra Livre Indigenous camp in Brasilia, Brazil's President Luiz Inacio Lula da Silva decrees six new Indigenous reserves, the first after a dearth under his far-right predecessor Jair Bolsonaro. Under the decree, Indigenous people are guaranteed exclusive use of natural resources on these lands, considered by scientists as a bulwark against Amazon deforestation -- a major challenge in the fight against global warming.
