What is a major consequence of deforestation near waterways?

Deforestation near waterways significantly disrupts the natural environment, leading to increased sediment runoff and reduced water quality as the correct answer indicates. When trees and vegetation are removed, the soil loses its structural integrity and ability to retain moisture. This results in more soil being washed away during rain events, leading to higher levels of sediment entering nearby rivers, streams, and lakes.

This sedimentation can cloud the water, making it difficult for aquatic plants to photosynthesize and reducing habitats for fish and other organisms. Furthermore, erosion can carry nutrients and pollutants into waterways, which can exacerbate issues like algal blooms, further harming aquatic ecosystems. The loss of vegetation also affects the natural filtration system that forests provide, which helps to maintain clean water and overall ecosystem health. Thus, the consequence of increased sediment runoff and reduced water quality reflects the significant environmental impact of deforestation near aquatic systems.
