The Amazon rainforest

The Amazon rainforest, home to half of the world's species, is crucial for Earth's water cycle and climate. It holds 1/5 of Earth's freshwater and produces 1/5 of its oxygen. However, deforestation for wood, cattle grazing, and crops threatens its existence, potentially disappearing in 50 years. This would worsen climate change by reducing carbon dioxide absorption. Conservation efforts, including forest protection and replanting, aim to preserve this vital resource.
