The missing lynx: how the rise of border walls has split up wildlife populations

There are now an estimated 74 border walls globally, up from just six in 1989, with more in the pipeline. “The hardening of international borders through fortification and militarisation is on the rise,” researchers say in the paper on the impacts of the Polish-Belarusian border wall. The US-Mexican border wall – which was found to have the most impact of those studied – bisects the ranges of 120 mammals alone.
