an example on how humans damage soil are things like:
overgrazing, this is when a farmer stocks to many animals like cows or sheep the animals damage the soil surface by eating the grass, digging into wet soil or compacting dry soil with their hooves
Overcropping, this is when land is being continuously under cultivation and is not allowed to follow between crops. this constant farming of the land reduces the soils ability to produce humus for soil
deforestation, is the cutting of large areas of forests leaving an large open exposed landscape this occurs for many reasons like selling wood or for a source of fuel while cleared land is used for livestock
we can prevent all of this by doing things like:
planting vegetation, matting, building retaining walls for plants,reduce watering, avoid soil compaction and many more
