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.

But Lula has promised to achieve “net zero” deforestation, allowing clearances only if an equal area of trees is replanted elsewhere.

Campaigners say the possible change of government has sparked a rush by criminal logging gangs.

Researcher Dionela Ferreira said: “People are racing to get hold of land because of the uncertainty. This is a very decisive year.”

“First they knock down trees, take away the valuable wood and then set fires to clear the land. The final stage is sowing grass and putting a cattle herd there for three to five years, then it’s soya beans.”

Scientists have forecast that the ecosystem, which acts as a buffer against global climate change by absorbing carbon dioxide, could be heading towards a “tipping point,” where swathes of forest will turn into dry savannah.
