What is one of the reasons World War 1 was so much more destructive than earlier conflicts?

One of the primary reasons World War I was so much more destructive than earlier conflicts was the introduction of advanced military technology, such as machine guns, artillery, tanks, and chemical weapons. These innovations allowed for mass casualties on an unprecedented scale, as traditional tactics were often ineffective against the firepower of modern weaponry. Additionally, the extensive use of trench warfare led to prolonged stalemates and horrific conditions, further contributing to the war's high death toll and devastation.
