While a border wall is built to the south — There exists a border wall to the north
Not built of concrete and steel — But of money, politics, and diplomacy
It’s not visual, but can be visualized — It’s existence seen circumstantially
When trespassed it grants sanctuary — To Canadian toxins and slag illegally
Squatters claiming possession adversely — To Columbia’s riverbed in perpetuity
Tho harmful to fish and benthics alike — Efforts at needed remediation
Result in collision — Against this wall unseen
Behind this wall extortionists lie — Wearing top hats, pinstripes, and tails
Canada making threats of reciprocation — If the U.S. pursues Columbia’s remediation
For past transboundary violations — by U.S. rust belt corporations
To this threat our government is complying — Hostaging Columbia, her inhabitants dying
Polluters escaping by recrimination — Victims subsidizing culpable corporations
Better both Nations not shield — Their transgressing corporations
For both Nations in violation — The Boundary Waters Treaty 1909
By allowing their pollutants — To cross the border line
The wall unseen is government — Constructed to protect their polluters
