Existing borders restrict natural migration patterns from "summary" of The Next Great Migration by Sonia Shah
When humans draw lines on a map, they are not just marking territory; they are also creating barriers that disrupt the flow of life. Animals, plants, and even microbes have been migrating for millions of years, following the rhythms of the Earth and the changing conditions of the planet. But when humans erect fences, walls, and other boundaries, they impede these natural migration patterns. These restrictions have devastating consequences on the environment. For example, animals that used to roam freely across vast landscapes are now confined to isolated pockets of habitat, leading to inbreeding, loss of genetic diversity, and ultimately, extinction. Similarly, plants that once dispersed seeds over long distances are now trapped in fragmented habitats, unable to adapt to changing climates or diseases. But it's not just the plants and animals that suffer from these artificial borders. Humans also pay a price for disrupting natural migration patterns. For centuries, people have moved across the globe in search of food, shelter, and better opportunities. But as borders have become more rigid and enforcement more stringent, many are now trapped in regions plagued by poverty, conflict, or environmental degradation. The irony is that while humans have the ability to move freely across the planet, they have chosen to restrict the movement of other species. This shortsightedness not only harms the environment but also undermines human well-being. By allowing natural migration patterns to resume, we can restore the balance of ecosystems, promote biodiversity, and create a more sustainable future for all life on Earth.
