The fertile surface of the earth on which we depend to grow crops is constantly getting damaged. It is very important to stop this because this is the main basis of diet on earth. This soil fills the lives of uncountable creatures other than billions of humans, but the greed and changing climate of human beings is continuously deteriorating the health of our earth. Healthy soil is vital for the world's growing food needs - but 33 percent of earth globally is in a very poor condition. That's causing problems, from food shortages to erosion - a major issue in sub-Saharan Africa.
