How did world war 1 and 2 effect the environment?

World War I and II significantly impacted the environment through widespread destruction and resource exploitation. The extensive use of chemical weapons, deforestation for military operations, and the destruction of infrastructure led to long-term ecological damage. Additionally, the wars accelerated industrialization and pollution, contributing to habitat loss and soil degradation. Post-war reconstruction efforts, while aimed at recovery, often prioritized economic growth over environmental sustainability, further complicating ecological restoration.
