The Amazon rainforest is the world’s biggest rainforest. It is in South America. It is so wide that it covers an area a little more than half the size of China. The Amazon River runs through the rainforest. It’s the world’s second longest river. The Amazon rainforest covers much of Brazil. The green colour on the national flag of Brazil stands for the rainforest.
However, climate change(气候变化) and human activities make it “sick”. Usually, the rainforest can fix itself. But now, it feels too “tired” to get better. According to a new study, many trees there may die, and the Amazon rainforest may turn into hot and dry grassland in a few years.
Why is the Amazon rainforest “sick”?
The Amazon rainforest is one of the world’s wettest places. But since 2005, three droughts have hit the rainforest. They were caused by climate change. The trees don’t have enough water to grow. What’s worse, as they become dry, they can easily catch fire.
Besides, people cut down rainforest trees for wood. They burn the forest to make farmland. All these kinds of activities made about 17% of the rainforest disappear.

The Amazon rainforest is like the lungs(肺) of our planet. The rich plants there take carbon dioxide(CO₂) out of the air and make oxygen. They make more than 20% of the planet’s oxygen. If the Amazon rainforest “dies”, there will be more CO₂ and our earth will become even hotter.
The Amazon rainforest is also home to over 3 million animals and plants. Many of them can’t live anywhere else. They would be very likely just disappear.
