According to a new study，the Amazon rainforest（亞馬遜雨林）may become grassland in a few years.
The Amazon is the world's biggest rainforest.Climate change（氣候變化）and human-activities make it "sick".Usually，the rainforest can fix itself.But now，it feels too "tired" to get better.The trees may die and the rainforest could turn into a hot and dry grassland.
The Amazon was one of the world's wettest places.But since 2005，three droughts（干旱）have hit the rainforest.They were caused by climate change.The trees don't have enough water to grow.What's more，as they become dry，they can easily catch fire.
What's more，people cut down rainforest trees for wood.They burn the forest to make farmland.They clear trees for minerals（礦產(chǎn)）.All these activities have caused about 17 percent of the rainforest to disappear.
The Amazon is like the lungs（肺）of our earth.They make more than 20 percent of the planet's oxygen（氧氣）.If the Amazon "dies"，there will be more CO2 and our Earth will become even hotter.The Amazon is also home to over 3 million animals and plants.Many of them can't live anywhere else.They could possibly just disappear.
