Often likened to the world's 'lungs,' the Amazon rainforest in Brazil seems to be suffering from a bad case of smoker's cough.br CNN reports that for the second year in a row, countless uncontrolled wildfires continue to rage at high levels there.br Scientists are concerned that the rainforest's destruction could eventually bring the Amazon to a point of no return.br Under President Jair Bolsonaro's administration, governmental measures to curb illegal fires have shown little impact.br Most fires in the Amazon are set by land-grabbers and wildcat ranchers, seeking to transform parts of the rainforest into their own lucrative agricultural enterprises.
