What occurs when land is overgrazed or overfarmed?

When land is overgrazed or overfarmed, it can lead to soil degradation, loss of fertility, and increased erosion. The excessive removal of vegetation disrupts the ecosystem, reducing biodiversity and impairing the land's ability to recover. This can result in desertification, where previously productive land becomes barren and uninhabitable, ultimately threatening food security and livelihoods. Additionally, the runoff from degraded land can contaminate water sources, further compounding environmental issues.
