The Amazon is the largest rainforest in the world, spanning 9 countries in South America and encompassing 7 million square kilometers. It is home to 10% of all known species and produces 20% of the world's oxygen. However, the rainforest is being cut down at an alarming rate, with more than 3,200 square kilometers being deforested in just 5 months of 2007. At this pace, over half of the Amazon could be destroyed by 2030, endangering countless plants, animals, and ecosystems as well as the global climate.
