A study published in Science modelling species extinction in the Brazilian Amazon has concluded that the extinction of many species in certain regions is inevitable. The study models several future scenarios ranging from “business as usual” to a “strong reduction” and found that even in the best case scenario deforestation will lead to the extinction of around 38 species locally. Future threats to the Amazon come from planned hydroelectric power plants and the risks of deforestation which might follow the changes to Brazil’s Forest Code.
