War causes problems, not solves them

War, it somehow solves our differences. Though, it hurts the enviroment, that is, the battlefield. Wherever it may be. Anyways, war solves silly stuff sometimes, and some mediocre not big problems. The bullet shells that get left behind from war aren't cleaned up, so an area that may have been untouched now is littered with bullet shells that take hundreds if not thousands of years to go away. Bunkers with barbed wire are left behind sometimes and pollute the once, a battlefield.
