Listen to the following passage:
Today, we are focusing on the significance of the Amazon rainforest. The Amazon is not only the largest tropical rainforest in the world but also plays a critical role in regulating global weather patterns. It is home to an enormous variety of wildlife and plants, many of which are not found anywhere else on the planet. Additionally, the rainforest contributes significantly to the planet's oxygen supply and absorbs carbon dioxide, which is essential in combating climate change. Our discussion will touch upon the various threats the Amazon faces, including deforestation, agriculture expansion, and climate change, and the importance of protecting this vital ecosystem for future generations.
