More than five million people die each year from diseases caused by using polluted water for drinking, cooking, or washing.About one-third of Earths population lives in areas that are experiencing water stress. Windbreaks are rows of trees and bushes planted between fields of crops, reducing the erosive power of the wind on the soil. Throughout human history, soil erosion has affected the ability of societies to produce an adequate food supply. Last Hunters, First Farmers: New Perspectives on the Worms are critical to soil health, and without soil Planet Earth would be little more than a lifeless rock. Soil conservation also creates economic opportunity. They include coal, petroleum (oil), and natural gas. Managing for soil health allows producers to work with the land not against to reduce erosion, maximize water infiltration, improve nutrient cycling, save money on inputs, and ultimately improve the resiliency of their working land. As a result, land can lose its arability and become a desert. Charles Darwin described earthworms as one of the most important creatures on Earth. by agriculture.
