The U.S.-Mexico border wall has been a point of contention in American politics since President Donald Trump made a promise to expand it during his 2016 presidential campaign. Along with political concerns about the effectiveness and morality of physical borders, worries about their environmental effects have also arisen.
Physical barriers have existed on the U.S.-Mexico border for decades, dating back to the early 1900s. In recent history, the fencing along the border was expanded under President George W. Bush when he signed the Secure Fence Act of 2006 — a move supported by former President Barack Obama, 2016 presidential nominee Hillary Clinton and Senator Chuck Schumer.
When Trump won the 2016 election, he came closer to realizing his promise of expanding the wall along the country’s southern border. Though he has been working against political opposition to building the wall, he has remained true to his promise. Soon after his inauguration, Trump signed an executive order to begin building the border wall — and in January 2019, the longest American government shutdown took place because, according to Trump, the federal government’s budget did not put enough money toward building the wall. In Trump’s final weeks in office, he is still pushing to fulfill his promise and continue building the wall along the southern border, making it harder for President-elect Joe Biden to be able to undo the actions of his predecessor.
Since the plan’s emergence, the expansion of the border wall has significantly alarmed scientists and environmentalists, as it has a number of negative environmental impacts. Bush-era fencing has resulted in flooding in parts of Arizona due to the buildup of debris blocking natural water flows during rainfall. The barriers do not allow animals to migrate within their habitats, limiting their ability to find food and water and escape from floods or fires. A Bioscience paper concluded that a full border wall would inhibit one-third of 346 native wildlife species from accessing 50 percent or more of their natural habitats. The border wall also disrupts wildlife refuges, national parks, Indigenous lands and surrounding communities.
The environmental effects of physical barriers have existed for years on the border between the U.S. and Mexico, but they have been exacerbated by Trump’s expansion plans. While Trump’s time in office may have only lasted four years, the environmental and social impact of the border wall will long outlast his presidency.
