What were the major environmental impacts of World War I?

Some major environmental impacts of World War I include deforestation, destruction of landscapes, pollution from chemical warfare, and disruption of ecosystems. The extensive use of artillery and trench warfare led to the destruction of forests and landscapes, resulting in loss of biodiversity and habitat destruction. The use of chemical weapons, such as mustard gas, caused severe pollution and contamination of soil, water, and air. Additionally, the war caused disruption to ecosystems due to the movement of troops, destruction of farmland, and the introduction of non-native species.
