Denmark’s government has begun constructing an iron fence in border line with Germany، her neighbor in the south. That fence extends for 70 km. Authorities declared that fence protects Denmark for invasion of pigs herds coming from German territories. Reports indicated that this procedure aims to prevent infection of African pigs fever that inflicted animals in some German states. Such a disease could threaten meat industry in Demark. It is worth to mention that meat products are among main exports of Demark to the other countries. The iron fence’s height is 1.5 meters. It originates from Badenborg city، some 220 km off Copenhagen، the capital city of Denmark.
