    The world's largest rainforest, the Amazon, grows over eight counties and covers 40 percent of South America. It makes about one—fifth of Earth's oxygen. People call it "the lungs of our planet.

However, the rain forest is in danger now. A large fire broke out in the Amazon last moth. As of Aug 27, it had lasted for 22 days.

In fact, the Amazon has seen a large number of fires this year. Between January and August, there were over74, 000fires —the highest number since 2013, the BBC reported.

Most of the fires came from human activities" CNN noted. Farmers in the Amazon have long used fire to prepare land for planting. But these fires can easily get out of hand.

The Brazilian government has sent soldiers to fight the fires. But scientists have said that it will take around 20 to 40 years to rebuild the forest's ecosystem. They have also said that the fires have destroyed 15 to 17percent of the rainforest, China Daily reported.
