Chapter 29.4, Problem 2CYL
Summary Introduction
To describe:
The process by which human activities interfere with the nutrient cycles and results in causing acid deposition, damages aquatic systems, enhances the greenhouse effect, and climate change.
Introduction:
Human activities that include the use of fossil fuels and chemical fertilizers have disrupted the global nutrient cycles of carbon, nitrogen, phosphorous, and sulfur. The agricultural demand of a growing human population leads to the excessive use of fertilizers containing phosphate, nitrogen, and urea. Overuse of these chemicals to the farmlands results in acid deposition and change in global climate.
