What consequence is associated with deforestation from agricultural practices?

Deforestation due to agricultural practices leads to soil erosion as one of its significant consequences. When trees and vegetation are removed, the soil is often left exposed and vulnerable to the effects of wind and rain. The roots of trees and plants play a crucial role in anchoring the soil in place, maintaining its structure and preventing it from washing away. Without this protective cover, the topsoil, which is vital for agriculture due to its nutrient content, can be rapidly eroded. This loss of topsoil not only diminishes soil fertility over time, leading to lower agricultural productivity, but can also result in sedimentation in waterways, disrupting aquatic ecosystems.

While the other options may seem attractive, they do not accurately reflect the ramifications of deforestation associated with agricultural practices. Enhanced biodiversity is negatively impacted as habitats are destroyed, increased crop yields cannot be guaranteed indefinitely due to soil degradation, and decreased food prices are not a direct outcome of deforestation. Instead, soil erosion can lead to increased food prices in the long run due to declining agricultural output.
