Brazil: a mural made with the ashes of the Amazon

Tired of seeing the lush Amazon destroyed for many years, Brazilian street artist Mundano decided to let nature speak for itself: he painted a giant mural in Sao Paolo using the ashes he collected from the burned rainforest, in order to raise awareness about climate change.

The giant 1,000-square-meter mural, titled "The Forest Firefighter," features a heroic character helplessly facing a raging fire.

Mundano, 36, gathered 200 kilograms of ashes from different areas affected by fires to create the mural on a building near Avenida Paulista, the main avenue that runs through Brazil's largest city.
