Which of the following is NOT a solution to soil erosion?

Removing natural vegetation is not a solution to soil erosion; in fact, it can exacerbate the problem. Vegetation, particularly trees and plants, plays a critical role in stabilizing soil through root systems that bind the soil together. It also helps to reduce the impact of rainfall on the soil surface, protecting it from being washed away by water runoff.

In contrast, planting trees, creating drainage diversions, and building terraces are all effective methods for controlling soil erosion. Planting trees increases soil stability and slows down water runoff, while drainage diversions can redirect excess water away from vulnerable areas to prevent erosion. Building terraces transforms steep terrain into a series of steps that reduce the speed of water flow, further preventing erosion. Thus, removing vegetation contradicts the principles of soil conservation and is detrimental to efforts made to combat soil erosion.
