The purpose of a border wall separating two countries is to prevent the free, uncontrolled passage of denizens from one country into the other; however, I think all would agree that the non-human denizens of these countries, should be able to continue their natural migratory patterns unimpeded.

The wall proposed by Donald Trump, however, would harm hundreds of already endangered species. So what's the solution? Some might say to simply not build the wall, but that would just leave others unhappy. Therefore, I propose a solution that will please both sides. Doggy doors. By scattering doggy doors or entrances like them, across the base of the wall, this problem would be solved.

Species affected include Jaguars, Grey Wolves and, even the symbol of America itself, the Bald Eagle.
