When agricultural operations are sustainably managed, they can preserve and restore critical habitats, help protect watersheds, and improve soil health and water quality. in addition to preserving the earth's natural resources, sustainable agriculture benefits the environment through helping maintain soil quality, reducing erosion, and preserving water. Plants and trees in agricultural systems help to retain and add water to underground aquifers. ... Together, they act as an important buffer in the landscape, preventing flooding, reducing water pollution from agricultural runoff and preventing erosion, while providing us with nutritious food at the same time. Farming creates opportunities to lift people out of poverty in developing nations. Over 60 percent of the world's working poor works in agriculture.
