Soil and human beings are inseparable. Please give an example.

It is no accident that humans and other creatures can survive on the earth. This is because all life on the earth depends on a fragile and loose soil covering the earth's surface. Without it, living things will never climb up from the ocean; There will be no plants, crops, forests, animals and humans. This precious topsoil is the soil on which we live. Soil, like the earth's plastic film, is located at the interface of the earth's atmosphere, hydrosphere, biosphere and lithosphere, which constitutes the PEDOSPHERE of the earth.

Soil is not only the foundation of our human life, but also the most important substance on the earth, and it is also the source and guarantee of human basic life. "Food is the most important thing for people, and food is based on soil", which shows that soil plays a great role in human survival, especially in agriculture. Due to the increasing population and the increasing demand for food, soil plays an increasingly important role in human life.
