World Soil Day is observed on December 5 every year across the world to bring the focus to the soil that nurtures us. Soil erosion is a major threat to the planet's soils. Soil erosion is the removal of the fertile top soil and if that goes away due to water, wind and tillage. Soil erosion affects soil health and productivity affecting quality of food. It also decreases crop yield. The theme of World Soil Day 2019 is "Stop soil erosion, save our future". The idea is to raise awareness on the importance of soil for healthy ecosystems and well-being of humans.
