Soil erosion steals fertile topsoil from farms

Soil erosion rapidly strips away the fertile topsoil vital for farming, a layer that takes centuries to form naturally. Human activities like deforestation and intensive plowing accelerate this loss dramatically. For instance, an estimated 24 billion tons of fertile soil vanish annually, about 100 times faster than it can regenerate. This depletion reduces crop yields and increases reliance on chemical fertilizers, impacting over 1.5 billion people in developing countries. Sustainable practices like contour farming can slow erosion by up to 90 percent, offering a hopeful solution.
