Border Walls pose a dilemma for the USA and all Countries seeking to prevent illegal immigration from overwhelming their societies..........Is there a way to block the entry of illegal people into our Country( I am in favor of this) while simultaneously allowing for the movement of animal populations to and fro( I am in favor of this as well)?......................"In Europe, the Croatian-Slovenian border area is currently home to scores of bears that have long roamed freely between the two countries"............... "Of the 10 or 11 wolf packs found in Slovenia, five traditionally have regularly moved across the Slovenian-Croatian boundary where a border fence is now being erected"............... "The threatened lynx also counts as homeland this area that was for centuries a borderless frontier of valleys, hills, and farmland" "Carnivores tend to simply turn away from the fences when encountering them"................ "If a young male bear or a wolf can’t cross the border to mate they will look for a more accessible female on their side of the fence"............... "The result is genetic isolation and inbreeding, a problem already threatening the region’s dwindling lynx population"............... "This can lead to an increase in diseases and unwanted genetic mutations that may ultimately lead to localized extinctions"............. "A 2011 study pointed out that the fence along the U.S.-Mexico border blocks 16 key species from about 75 percent of their habitat"............... "The U.S. Fish and Wildlife Service has said that a fence proposed by President-elect Donald Trump would impact 111 endangered species and 108 migratory birds"................ "In Asia, nearly the entire 2,900-mile Chinese-Mongolian border is fenced,impacting species such as the Asiatic wild ass and the Mongolian gazelle"...............Truly a conundrum we face in remaining a sovereign nation governed by the rule of law and not overrun with illegal migrants,,,,,,, while simultaneously optimizing biodiversity in the Americas
