How Does the Amazon Rainforest Contribute to the Earth’s Atmosphere?

The Amazon Rainforest produces about 20% of the Earth’s oxygen.

The Amazon Rainforest produces 20% of the oxygen in the Earth’s
atmosphere. Spanning across nine countries in South America, it is the
largest rainforest in the world, about 2.3 million square miles (7 million
square kilometers) and represents 50% of the world’s total rainforest
land. The Amazon Rainforest contributes to regulating the temperature of
the Earth by absorbing carbon that is emitted into the atmosphere when
fossil fuels are burned, which is thought by scientists to cause the
average global temperature to increase. If warmer temperatures dry out its
water sources, the rainforest could contribute more carbon to the
atmosphere than it absorbs, as it did during a 2005 drought.
