Dirt! The Movie (2009) on Netflix

Plot summary

Dirt is the living source of life on Earth, created over four billion years of evolution, and humans are built from the same material. Its gifts include food and shelter, fuel and medicine, ceramics, flowers, cosmetics and color. For most of the past ten thousand years people recognized their dependence on dirt and on the natural world, and tended the soils that fed them. That connection was lost as the species became greedy and careless, and dirt was treated as something dirty. Agriculture, mining and the paving of land for cities now damage it.
