What are the human activities that affects soil?

These include land use change, land management, land degradation, soil sealing, and mining. The intensity of land use also has a great impact on soils. Soils are also subject to indirect impacts arising from human activity, such as acid deposition (for example, sulphur and nitrogen) and heavy metal pollution.

What are the activities that destroy the soil?

Soil erosion occurs naturally by wind or harsh climatic conditions but human activities include overgrazing, overcropping and deforestation. Overgrazing occurs when farmers stock too many animals such as sheep, cattle or goats on their land.

What makes soil healthy?
