How The Amazon Rain Forest Contributes To 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.
