Has Brazil’s president lost his marbles?

In this age, of unhinged presidents, it appears he has set a new low … er, standard.

Brazil’s President Jair Bolsonaro has accused Hollywood actor Leonardo DiCaprio of “giving money to set the Amazon on fire.”

The president gave no evidence but in the past has accused NGOs critical of his policies of starting fires that ravaged the rainforest this year, the BBC reported.

Several arrests have been made amid controversial and unproven allegations fires were started to obtain funding.

DiCaprio, who has pledged US$5 million for the Amazon, denied Bolsonaro’s highly questionable claim.

The latest comments appear to arise from the arrest of four volunteer firefighters from northern Pará state on allegations they started fires to generate NGO donations.

Rights groups, NGOs and critics claimed the police operation against them was politically motivated and an attempt to harass environmental groups, the BBC reported.

Fires that burned in August this year caused global concern for the “lungs of the planet.”

His latest accusation came during brief remarks at the presidential residence on Friday. “This Leonardo DiCaprio is a cool guy, right? Giving money to torch the Amazon.”

He gave no evidence and did not elaborate, although the statement appeared to echo a live webcast he gave on Thursday.

That revolved around the environmental organization, the World Wildlife Fund (WWF), and allegations, denied by the WWF, that it had paid for images taken by the arrested firefighters, who have since been released.

Bolsonaro said: “So what did the NGO do? What is the easiest thing? Set fire to the forest. Take pictures, make a video. [WWF] makes a campaign against Brazil, it contacts Leonardo DiCaprio, he donates $500,000.

“A part of that went to the people that were setting fires. Leonardo DiCaprio, you are contributing to the fire in the Amazon, that won’t do,” he said.

The actor and environmental activist released a statement saying: “Although they are certainly worth supporting, we have not funded the organizations that are currently under attack.

“The future of these irreplaceable ecosystems is at stake and I am proud to be part of the groups that protect them.”

He praised “the people of Brazil working to save their natural and cultural heritage.”

WWF also said it had received no donations from the actor, whose Leonardo DiCaprio Foundation focuses on environmental projects, the BBC report said.

Bolsonaro’s accusation was mocked by opponents.

Senator Randolfe Rodrigues tweeted: “How desperate. Our negligent and incompetent president, who is responsible for unprecedented environmental dismantling, blames DiCaprio but not his own administration which is incapable of taking a single step without destroying something.”

For several weeks in August, fires burned in parts of the Amazon at a rate not seen in years, sparking international concern over the condition of the “lungs of the planet.”

The Amazon is the largest rainforest in the world and a vital carbon store that slows down the pace of global warming.

In August there were thousands of individual fires, almost three times as many — 30,901 — as in the same month last year.

According to his critics, like Don Quixote, Bolsonaro is in constant fight against windmills, seeking imaginary enemies as a way to justify his actions and to please his supporters’ base — that’s shrinking more and more.
