At the United Nations General Assembly, Brazil’s Jair Bolsonaro opened the proceedings with the rather bizarre comment that the Amazon – which has been on fire for weeks – is ‘practically untouched’ and that a ‘lying and sensationalist media’ had been fanning the flames of fake news. The Amazon, 60% of which is inside Brazil, is not – Bolsonaro said – the ‘heritage of humankind’. It is Brazilian territory, he said, and if Brazil wants to cut it down, then so be it. Protests have taken place around the world against the Amazon fires, since it is well-recognised that the Amazon is one of the major carbon sinks on the planet. If there is 25% deforestation of the Amazon, then the rainforest would have reached a point of no return. At that point, the vegetation loses its capacity to regenerate and would likely devolve from a rain forest into a savannah. We are in the age of madness again, on the edge of the destruction of the Amazon, an age that calls to be brave and to be bold.
