The Amazon Rainforest is the largest rainforest in the world, representing over half of the planet's rainforests. It contains an estimated 390 billion trees across 16,000 species and is home to one in 10 known species globally. More than 30 million indigenous people rely on the Amazon's natural resources for survival. However, the rainforest is threatened by deforestation mainly for cattle pasture and agriculture. Deforestation has negative environmental impacts such as increased temperatures in Brazil and damage to the region's water supply.
