The description "Soil digger removes roots of large trees to plant oil palm" refers to a destructive agricultural practice of removing large trees and their root systems to make way for the planting of oil palm trees.

Oil palm is a highly profitable crop used for the production of palm oil, which is commonly used in a wide range of food products, cosmetics, and biodiesel. However, the expansion of oil palm plantations often comes at the expense of native forests and their ecosystems.

Removing the roots of large trees can have devastating effects on the surrounding environment. The roots of these trees help to stabilize soil and prevent erosion, and their removal can lead to soil degradation and increased risk of landslides. Additionally, the removal of large trees and their root systems can have a significant impact on the biodiversity of the surrounding ecosystem, displacing native wildlife and disrupting ecological balances.

Furthermore, the expansion of oil palm plantations often involves the use of harmful chemicals and intensive farming practices that can contribute to deforestation, soil degradation, and water pollution.

In summary, the practice of removing large trees and their root systems to plant oil palm is a destructive agricultural practice that can have significant negative impacts on the environment and the surrounding ecosystem.
