Environmental biology addresses soil degradation by studying the processes that lead to soil erosion, nutrient depletion, and contamination. It examines the impact of agricultural practices, deforestation, and urbanization on soil health. Environmental biologists develop sustainable land management practices, such as crop rotation, cover cropping, and reduced tillage, to prevent soil erosion and maintain soil fertility. They also advocate for soil conservation policies and practices that enhance soil structure, increase organic matter content, and reduce pollution, thereby ensuring the long-term productivity of the soil.
