Transboundary Ecological Impacts of a Border Wall

For all the recent talk about a U. S.-Mexico border wall, most rhetoric has ignored its significant environmental impacts.  Funding efforts for this massive, concrete wall are temporarily shelved; yet No Water No Life wants to promote discussion of the important watershed threats this wall poses, as the proposal is likely to reappear.

Those who think the almost-2,000-mile borderline from Texas to Tijuana would not have environmental impacts don’t understand that this corridor is more than an empty, arid space.  There are tenuous desert ecosystems within critical and vulnerable watersheds.  The health and very existence of local flora and fauna would be threatened.  Resultant flooding would increase.  Meanwhile, many argue that little – if anything – would be gained from constructing a border wall.

Cost of Wall – According to the Washington Post, the Wall will take over 3 years to construct at an estimated cost of $21.6 billion using taxpayer dollars.  This does not even include the $10 million/year for repairs that is currently spent .

Wildlife – The desert is home to bison, saguaro cactus, desert tortoise, prairie dogs, blackbirds, foxes, hawks and countless other species. Added wall construction would impact more than 100 endangered species, 108 migratory bird species, 4 wildlife refuges and critical wetlands.  More than 30 environmental and cultural laws have already been waived in the name of “national security” for just the present border-wall sections.

Migration Corridors – One of the most devastating qualities of the border wall would be the abrupt blockage of migration corridors.  The wall wouldn’t just keep out unwanted people.  It would prevent species from moving freely to habitat crucial to their survival and to lands they have used for thousands and thousands of years.

Flash Floods – Most of the year, the desert is a very dry place to be; but when it rains, torrents come down ferociously.  Flash floods dump more than 1,000 cubic feet of water per second into the ecosystem, which carry debris downstream with it. A concrete border wall would further exacerbate severe erosion, chaos and destruction in nearby border towns above and beyond the flooding already caused by existing border-wall sections.

Tohono O’odham Tribe – The Tohono O’odham are a nation of indigenous peoples on the American continent. Their tribe is in a unique transboundary situation because their territory spans both the U.S and Mexico. This tribe is vehemently opposed to a larger border wall as it would directly overrule their sovereignty and would prevent them from reaching their sacred lands.  They also know it would disrupt regional ecosystems.

Microbeads – Harm Behind the Product

July 7, 2016

It’s time to rethink the hygienic products we use. Those tiny little beads in our peach scented facial scrub are doing much more than just exfoliating our skin. A large number of studies have shown that these tiny microbeads have extremely harmful impacts on the environment.

Once they get swept down the sink, the beads don’t just simply disappear. Microbeads are too small to be caught in wastewater systems, and end up flowing out to pollute our rivers, lakes, and oceans.

In 2011, a survey of the Great Lakes showed that Lake Eerie had up to 600,000 plastic particles per square kilometer.

Thankfully President Obama signed a bipartisan bill in December that bans microbeads, but it won’t take affect until 2017. Just last week, Canada listed microbeads as toxic, and are likely to pass a ban on the product as well.

In the meantime, be conscious of the beauty and hygienic products you are using!

To find out if a product you are considering purchasing has microbeads, there is an app available from Beat The Microbead that will give information on any product when they are scanned.

Here is a list of common products that contain microbeads.

USGS Studies Pharmaceuticals in our Streams

The USGS just released a study of 59 streams in the Southeastern United States ranging from Georgia to Virginia. Alarmingly, the study showed that every single one of these streams tested positive for pollution by pharmaceutical compounds.

These compounds have a wide variety of negative impacts on the entire aquatic ecosystem including altering the base of the food web, affecting neurotransmitters for many aquatic insects, and affecting the reproductive health of fish.

One of the main causes of this pollution is homeowners’ tendency to flush unused medications down the toilet. There are alternatives to this harmful habit.

There are many community based drug “take-back” programs you may use to dispose of your medicine – call your local government to find out more information. Otherwise disposing your medicine in the trash is the best option. Take action today to prevent your medicine from polluting local waterways.

Share this information with your friends, and let us know how you help keep your streams clean.
