This booklet examines both the challenges and opportunities agriculture offers for improving water quality and, in turn, human and environmental health. It also explores why implementing sustainable farming practices—like planting cover crops, rotationally grazing livestock, and maintaining riparian buffers—is one of the most straightforward and cost-effective solutions available for alleviating water pollution. Although the geographic focus for this booklet is Pennsylvania, the core issues discussed—water, farming, and a sustainable future—are global.
