“Trump says in a video on his campaign website, ‘It will be a great wall. It will do what it is supposed to do: keep illegal immigrants out.’ …
Far from being a barren wasteland, the US–Mexico borderlands have some of the highest diversity of mammals, birds and plants in the continental United States and northern Mexico — including many threatened species.
A wall could divide species that make a home in both nations. Bighorn sheep, for example…
Birds that rarely fly, such as roadrunners, or those that swoop low to the ground, such as pygmy owls, could also have trouble surmounting the wall.” (http://www.nature.com/news/trump-s-border-wall-pledge-threatens-delicate-desert-ecosystems-1.20431)
But for sure Trump also has a plan for all the ‘wall-kill’. “Short on detail”, long on sheep.
“The American Farm Bureau Federation has claimed on its website and elsewhere that EPA would take over all farming and land use, control ‘virtually all water,’ and even regulate puddles and wet spots.” (http://www.nrdc.org/media/2014/140715.asp)
The American ‘puddle’ is of course 20 fluid ponds, while the British ‘puddle’ is defined as three to five cubic centidrips, must contain at least 85% water and must remain in place for at least six months of the year. Seasonal puddles are not regulated.
