Question

Quizplus · Accepted Answer

Urban development often involves clearing land and removing trees and other vegetation, which reduces the amount of oxygen released by autotrophic plants through photosynthesis. This can have negative impacts on air quality and local ecosystems. Choice A is unlikely, as human disturbance often leads to increased waste (such as construction debris) which could potentially increase soil bacteria activity, but this is not always the case. Choice C may be true in some cases, but this would depend on the specific urban development and location. Choice D is unlikely as human disturbance often leads to increased toxins in soil and groundwater due to construction and other human activities.
