Deforestation is primarily caused by human activities such as clearing land for agriculture, logging for timber and paper products, and building infrastructure such as roads and dams. These activities lead to the loss of forest cover, which can have significant environmental impacts, including soil erosion, loss of biodiversity, and increased greenhouse gas emissions. Among these causes, agricultural expansion is the most significant because it accounts for the largest area of forest loss globally. This is driven by the increasing demand for food and other agricultural products, resulting in the conversion of forests into farmland.
