What were the reasons for the extensive loss of life and property damage in the ww1?

The extensive loss of life and property damage in World War I was primarily due to the scale of the conflict, involving multiple nations and advanced military technologies such as machine guns, artillery, and poison gas. Trench warfare led to prolonged stalemates and horrific conditions, resulting in high casualty rates. Additionally, the war's total nature involved not just soldiers but also civilian infrastructure, leading to widespread destruction and famine in affected regions. The mobilization of entire societies for war further exacerbated the human and material toll.
