The correct answer is: A. World Soil Day

World Soil Day is an international observance held annually on 5 December to raise awareness of the importance of soil and sustainable soil management. It was established by the United Nations Food and Agriculture Organization (FAO) in 2002.

The theme for World Soil Day 2022 is “Stop Soil Erosion, Save Our Future”. The theme highlights the importance of soil conservation and the need to protect our soils from erosion.

Soil is a vital natural resource that provides us with food, water, and shelter. It also plays a vital role in the climate system and the health of our planet. However, soil is under threat from a number of factors, including deforestation, overgrazing, and unsustainable agricultural practices.

World Soil Day is an opportunity to raise awareness of the importance of soil and to promote sustainable soil management practices. We can all play a role in protecting our soils by making small changes in our daily lives, such as composting, reducing food waste, and planting trees.
