Biden becomes first sitting US president to visit Amazon rainforest

US President Joe Biden recently became the first sitting American president to visit the Amazon rainforest, where he witnessed the devastating effects of deforestation and drought. The Amazon region is the world's largest tropical rainforest and stores significant amounts of carbon dioxide, a greenhouse gas that contributes to climate change. Biden pledged $50 million to Brazil's Amazon Fund to support conservation efforts.
