understandable, but then we have wo1 and the old battlegrounds in Belgium and northern France are not wastelands. They do still find tons and tons of old bombs each year though farmers drive with a armor plates under there tractors and they pile up the unexploded explosives next to their field
“The Zone rouge (French for 'Red Zone') is a chain of non-contiguous areas throughout northeastern France that the French government isolated after the First World War. The land, which originally covered more than 1,200 square kilometres (460 square miles), was deemed too physically and environmentally damaged by conflict for human habitation. Rather than attempt to immediately clean up the former battlefields, the land was allowed to return to nature. Restrictions within the Zone rouge still exist today, although the control areas have been greatly reduced.
The Zone Rouge was defined just after the war as "Completely devastated. Damage to properties: 100%. Damage to Agriculture: 100%. Impossible to clean. Human life impossible".

The areas are saturated with unexploded shells (including many gas shells), grenades, and rusting ammunition. Soils were heavily polluted by lead, mercury, chlorine, arsenic, various dangerous gases, acids, and human and animal remains. The area was also littered with ammunition depots and chemical plants. The land of the Western Front is covered in old trenches and shell holes.
Each year, numerous unexploded shells are recovered from former WWI battlefields in what is known as the iron harvest. According to the Sécurité Civile, the French agency in charge of the land management of Zone rouge, 300 to 700 more years at this current rate will be needed to clean the area completely. Some experiments conducted in 2005–2006 discovered up to 300 shells per hectare (120 per acre) in the top 15 centimetres (6 inches) of soil in the worst areas. [better source needed]
Some areas still remain heavily contaminated. For example, at a site in the vicinity of Verdun known as the Place à Gaz (49.3116°N 5.5888°E), arsenic constitutes up to 176 grams per kilogram (18%) in the soil. In the 1920s, chemical warfare shells containing arsenic were destroyed there by thermal treatment.
