Donald Trump's proposed border wall could threaten the survival of endangered species and disturb fragile ecosystems in the southwestern U.S. and northern Mexico, according to a top scientist. “We know how important the natural movement of wildlife is for the persistence of many species,” Clinton Epps, a wildlife biologist at Oregon State University, told scientific journal Nature. Building a wall “would be a huge loss,” Epps added. This "top scientist" doesn't understand that animals and wildlife always find a way around obstacles. Trumps wall might even help the animals, as the wall could provide shade and shelter for animals away from the hot desert sun. So the real fact hear is that wild animals will likely benefit from Trumps wall, and not get harmed from it. You would almost have to bet these are one of these government supported scientist, who has likely participated in Obama's and the UN push for climate change. Mankind has in fact built many obstacles for nature to figure out, and nature always tends to prevail in finding a way around those obstacles. Most animals in the southwest can climb stuff anyways, so this statement that Trumps wall will affect the environment is based in pure stupidity likely ordered by the Obama team. Trumps wall will benefit Americas security, and it will also benefit nature by giving wildlife animals a home and shelter in the desert southwest.
