FILE - In this Monday Jan. 28, 2019 file photo, workers erect a fence along the Denmark Germany border at Padborg, Denmark. Officials say the number of wild boars in Denmark has fallen since a 70-kilometer (43.4-mile) fence was erected along the German border to protect the valuable Danish pork industry. The fence was put up last year in an attempt to prevent wild swine crossing from Germany and breeding with farm pigs or possibly passing disease. (Frank Cilius/Ritzau Scanpix via AP, File)
