The Amazon River flows through the Amazon rainforest, which is the "lungs of the earth".

1. Poor soil, accelerating desertification

2. Soil and water loss, the amount of water flowing into the Amazon River decreases, and the amount of sand transport increases. The river channel is blocked, and floods and waterlogging disasters frequently occur in the Amazon Plain

3. Ecological damage in the river basin, and the number of animal and plant species decreases.

4. The role of the rainforest is weakened, the absorption of greenhouse gases decreases, the global climate warms, the sea level rises, and many lowlands of island countries are submerged, such as Singapore

5. Bringing extreme climate, such as the El Nino effect and the La Nina phenomenon

6. Changes in atmospheric circulation, weakening of high-latitude and low-latitude circulations, and strengthening of mid-latitude circulations, leading to frequent droughts and floods in coastal countries and more drought in inland countries.

7. Impact on agriculture. Agricultural production will decrease. Subtropical plants can be planted in the temperate zone, but the overall production will decrease, which will lead to a food crisis.
