  • This episode starts with a proposition:

  • how about we rip the United States and Mexico

  • apart from each other?

  • Geographically speaking.

  • It would open up new trade routes

  • that would make a ton of money

  • for both countries,

  • and it could create a whole new

  • tourism industry for cities along the canal.

  • The U.S./Mexico border

  • is 3,111 kilometers (1,933 miles) in length.

  • As of early 2019,

  • approximately 2,058 kilometers (1,279 miles)

  • is unfenced due, in large part,

  • to the Rio Grande River

  • acting as a natural barrier

  • between the countries.

  • If we're going to go ahead and build a canal

  • along this border, this giant river

  • seems like a natural starting point,

  • don't you think?

  • But before we bring our big machines

  • down there to expand the river,

  • maybe we should stop and ask ourselves:

  • how is this going to impact the surrounding environment?

  • The Rio Grande provides water to six million people,

  • so having ships of all sizes passing through it,

  • and creating pollution, probably wouldn't be a good idea.

  • Plus, if we were to expand the Rio Grande along the border,

  • we'd be crossing through six separate eco-regions.

  • Along this stretch, there are 62 species of animals and plants

  • that are currently listed as critically endangered.

  • Our Rio Grande canal could be just enough to push these species

  • over the edge from endangered to extinct.

  • It could also wreak havoc with seasonal migration for some species,

  • and severely limit food sources and mating.

  • Okay, I agree, this is starting to look pretty complicated.

  • So how about we look at an existing canal for guidance?

  • The Panama Canal cuts across the Isthmus of Panama,

  • connecting the Atlantic Ocean with the Pacific Ocean,

  • using a series of locks to adjust to the changing elevations from ocean to ocean.

  • In total, 14,000 ships a year make use of it,

  • with larger cargo ships having to pay upwards of $1 million to use it.

  • That's a lot of money that could be funneled to North America instead.

  • If we were to build a canal that matches the width of the Panama Canal,

  • we'd have to move about 53 billion cubic meters of earth, at a price of $11 trillion.

  • And that number is just for the length of the Rio Grande,

  • which is the shared border from the Gulf of Mexico to El Paso, Texas.

  • The Rio Grande would need reinforced concrete walls,

  • and barriers installed along its shores.

  • And it would need to be dug deeper in some areas.

  • If we follow the operations guide of the Panama Canal,

  • a specially trained canal pilot

  • would have to navigate any large boat for the duration of its trip through the canal.

  • This might present some issues since, in the case of the Panama Canal,

  • we're dealing with hours to go across the canal,

  • whereas here it would be days that another person has charge of the ship.

  • We'd also have to find a way to deal with border crossings on foot or by car.

  • There are 47 legal points of entry between the U.S. and Mexico.

  • Sure, we could replace those with bridges, but

  • each of those bridges would cost approximately another $600 million.

  • Even though this project would bring a lot of benefits,

  • it seems like it would bring even more questions.

  • Such as, who would be paying for all this?

  • How much would be covered by the U.S., and how much by Mexico?

  • It wouldn't be economically feasible for either country,

  • since it would cost trillions of dollars

  • just to finish construction across a couple of states.

  • To fund such a massive project,

  • could mean taking that money from more vital social or medical programs,

  • anything deemed expendable by those with interests in the canal.

  • The political fallout from this could also be significant.

  • we'd literally be making a cut through North America.

  • This could create a new source of global instability,

  • something that may be viewed as an

  • us-against-them mentality by other countries.

  • Maybe all this international trade talk would be easier

  • if we just didn't have those pesky oceans dividing us all,

  • but that's a story for another WHAT IF.
