Walls vs. Coexistence

A long time ago in a land far away, there once was an emperor who wanted a wall. It is always one grandiose scheme or another, and that one was defensive. The longest defensive barrier ever built to keep out invaders. Begun in the Qin Dynasty, and later rebuilt in the Ming Dynasty, the Great Wall of China covered much of the northern border of China.

We all know how well that worked out. For over 2,000 years the nomadic Mongol tribe of the north regularly invaded and conquered the Chinese Empire.

Extending through all types of terrain including mountainous regions, the Great Wall itself took its toll on the Chinese. Thousands of workers died in the construction, and many are thought to be buried under the very wall they were assembling.

And what of the wildlife? On that continent: wild boars, oryx gazelle, and the Chinese monal pheasant. Red fox, Siberian Roe Deer, Hog badger, and African Hoopoe in forests. Whatever became of the wildlife with the wall?

As in China, the U.S./Mexican border runs through a delicate ecosystem. Traversing mountains, rivers, desert, and scrub brush, various species have been crossing it for billions of years. On this continent: mountain lions, bobcats, cougars, desert bighorn sheep, the endangered N.A. jaguar, and ocelot. Roadrunners and low flying birds such as the pygmy owl, as well as annual  migrations of Monarch butterflies.

“Border infrastructure not only blocks the movement of wildlife, but… destroys the habitats, fragments the habitats and the connectivity that these animals use to move from one place to another,” notes Sergio Avila-Villegas, at the Arizona Sonora Desert Museum, in Tucson.

As it is, with approximately 40% of the U.S./ Mexico border presently fenced, desertification, erosion, pollution, groundwater depletion, and distressed animals are already evident. Construction of a wall would further disturb watersheds and waterways, resulting in possible flooding.

“For some species, the desert bighorn sheep, for example, you have decent populations on both sides of the border. But they depend on these movements for maintaining genetic diversity, for recolonizing habitat where they’ve suffered long extinctions,” states Dr. Clint Epps, a biologist at Oregon State University.

According to the World Wildlife Fund, world wildlife biodiversity is diminishing at an alarming rate. A complete divide along the US/Mexican border would isolate subpopulations of many animal species, hampering gene flow. Plants too are dependent on wind to spread their seeds. A wall would disrupt pollination and have effects on the ecosystem as a whole.

You have to remember, nature doesn’t know borders. A wall, any wall—one for defense, another to control immigration, can easily create more disorder than order.

In the words of Michael Crowther, CEO Indianapolis Zoological Society, we “… must recognize that we are a part of this world, and trying to become apart from the rest of it is not a viable solution in the long term. We must create a new focus on what our countries share in common—our biodiversity, our ecosystems and our planet—rather than what makes us different. Then, and only then, can we begin to have a meaningful dialogue around flexible solutions that benefit humans, ecosystems, and wildlife on both sides of the border.”

  1. Beautiful, Kim. I’m going to China next month–your words will be on my mind as I view the Great Wall for the first time in my life.

    Excellent — and different — take on the wall, and Paul’s photo says you were there and that your facts were (at least partially) learned there.

    I’d suggest you send it as an OpEd to Seattle Times, NYT, San Francisco Chronicle, etc.

    FYI: I know that Paul is your husband, but no where does your first nor last name appear: not in the sender nor reply info, not in the info at the very bottom.

    There are probably reasons for protecting your identity, but I would seriously recommend that you at least sign your blog, Kim Mayer.

    All best, Alice

    Love the blue marble view of one planet. Walls are schemes that we forget to talk out what connects us.

  4. This is a really great point, people forget about the fauna and flora that they will impact with their politics. If we don’t care for our planet we ALL die, I don’t understand why people don’t “get” that.

  5. “You have to remember, nature doesn’t know borders. A wall, any wall—one for defense, another to control immigration, can easily create more disorder than order”–Beautifully said!
