CAMPAIGNERS are warning that the second round of voting in the Brazilian presidential elections has sparked a rush to destroy more of the Amazon rainforest.

The Workers Party candidate, former president Luiz Inacio Lula da Silva, commonly known as Lula, is favourite to win the second round of voting against the incumbent Jair Bolsonaro on October 30.

President Bolsonaro has been accused of giving the green light to illegal loggers, gold-miners and ranchers.
