Which of the following statements is unrelated to how important soil is to human life?

Soil is very important for us because:

1. It provides us with a source of food and water
2. It stores and purifies water
3. It provides a habitat for wildlife and animals
4. It provides us with minerals to construct machinery
5. it provides fuel and energy
6. it promotes the growth of plants which give us food and shelter to live.
7. it provides raw materials and resources for development

Different colours of soil do not provide any significant value in human life. Hence, it is unrelated to the importance of the soil.
