But that would all change if the fence goes up. The massive structure would interrupt range patterns and cut off access to many species’ food and water sources. And the animals can’t simply go around the fence, which will extend well past their territories. “We can’t just shrink down the amount of available habitat and expect everything to be OK,” says Heather Zichal, who works on environmental issues for Sen. John Kerry. “Animals will die off, stop reproducing. It’s the basic law of ecology.”
Maybe the fence, which will stretch in sections from Brownsville, Texas, to San Diego, will have a series of giant doggy-doors to let the wildlife through? Doubtful. Over the years, the federal government has spent millions building vehicle barriers that keep vehicles out but let animals pass through, but they will be torn down to make way for the fence. In fact, because the bill falls under the purview of Homeland Security, the department can bypass environmental regulations that protect fragile terrain and animal habitats.
