Hey environment, here's a big middle finger to you.
From ABCNews "Trump has called for a 30-foot solid, concrete wall along the border to curb illegal immigration, and although Department of Homeland Security Secretary John Kelly recently acknowledged that a wall "from sea to shining sea" was unlikely, many experts said there was no way of telling the full impact on the surrounding environment. The wall would likely cost $22 billion and take more than three years to build, according to an internal DHS memo.
Scientists and conservationists said such drastic increases in border security could be devastating for hundreds of species, and potentially lead to extinction in the U.S. for endangered or threatened animals like jaguars, ocelots, and the Mexican gray wolf."
