Final answer:
If deforestation continues on Earth, the most likely event to keep happening is soil erosion.
Step-by-step explanation:
If deforestation continues on Earth, the most likely event to keep happening is soil erosion. Deforestation disrupts the natural balance of vegetation, leading to the loss of tree roots that hold the soil together. Without trees, the soil becomes vulnerable to erosion by wind and water, causing significant damage to ecosystems.
