Dirt is dirty and I would not think that it matter or play a vital role in the ecosystem. This is of course wrong. There are minerals and other important substances in it that keeps everything in and on the ground living. Plants and animals living underground, as well as the ‘health’ of the ground to keep erosion away.
I was blown away the fact that people that own lands to grow plants really took care of their dirt and know whether their dirt is good or not by smelling and tasting it. I would never think that just from this two factors we can actually determine the health of dirt.
It’s very scary how us human have the power to kill the ground; killing the ecosystem. Turning a land covered in water into a desert wasteland. It is devastating, if this keeps happening. In the end, we might actually kill the world by not only causing the global warming but also by hurting the ground which can lead to a chain effect to the ecosystem.
