An almost 700 mile long fence between the US and Mexico border is raising alarm with environmentalists concerned about impacts to wildlife and the surrounding ecosystem. The fence is being created to help curb the flow of illegal immigrants into the United States; a construction move that Mexican officials claim will cause irreparable environmental damages. From the article,

A report prepared for the Mexican government by experts and environmental activists from Mexico and the US said the barriers could isolate border animals into smaller groups, affecting their genetic diversity. These include jaguars, Mexican black bears and the endangered antelope-like Sonora Pronghorn.

Additionally, the massive strong lights and other equipment adorning the perimeter line will upset animals with nocturnal systems and natural radar.

Proposed additions to the fence to help abate environmental concerns include "green corridors" — to easily allow the passage of animals, pollen, and other organisms — but not humans. These corridors would not have roads and would be difficult for peope to transverse. Additionally, environmentalists are petitioning for permeable sections that would allow water, pollen, and insects to pass — thereby keeping some form of connection between habitats.

Something tells me that the US Government is not going to let environmentalism stand in its way to keep out illegal immigrants. A 700 mile long fence seems like a rather crude and ancient way of dealing with the situation, but I’m at a loss on the subject to suggest alternatives. One does feel that animal habitats or migration routes will be cut off as a result. Have we given this construction project any thought beyond its intended use? Hit the jump for more.
