The London Independent says that Trump’s Mexican wall could emit nearly two million tons of carbon dioxide and cut off endangered animals from their territory. Trump has not said exactly what the wall will look like, or what it will be made from, but it could be 10-17 meters high.Environmentalists are worried about emissions and also that the wall will prevent many animals from moving into different areas and from heading north as the climate warms.

The Sierra Club’s Borderlands project Dan Millis said “In terms of climate adaptation, building a border wall is an act of self-sabotage”.
