Sting has publicly condemned Brazil's response to the fires raging across the Amazon rainforest. In a post on Facebook, the music icon criticized President Jair Bolsonaro -- who rejected a $22 million aid package to help fight the fires.

Sting wrote, "Populist leaders citing nationalist agendas, or claiming that climate change and its handmaidens are a hoax, are guilty of much more than standing by and doing nothing. This is criminal negligence on a global scale."

He continued, "Amazonia is on fire at an unprecedented rate – 80% up from last year and with 39% more deforestation – and the world is suddenly taking notice. This is no place for the outdated bromides of nationalism in a world where we all breathe the same air and where we will all suffer the consequences of this willful negligence."

He added, "Calling Amazonia the 'lungs of the Earth' may not be exactly anatomically correct, but it does convey that it is a vital and irreplaceable link in the chain of wellbeing on our planet in the increasingly narrow band of climatic vectors where human life can survive. We simply cannot afford to let it burn.
