Biden is expected to take an aerial tour over part of the world’s largest tropical rainforest, meet local and indigenous leaders and visit an Amazonian museum as he looks to highlight his commitment to the preservation of the region.

Joe Biden will become the first sitting U.S. president to visit the Amazon rainforest on Sunday as he flags the dangers of global warming often dismissed by Donald Trump, who enters the White House in January vowing to scrap measures to fight climate change.
