2019 Gulf Dead Zone Could Set Records

The Gulf of Mexico “dead zone” is a region of oxygen-depleted water off the Louisiana and Texas coasts that results from staggering levels of upstream nitrogen released from farms and other sources. The nitrogen then kills marine life and creates toxic algal blooms, much like the ones we witnessed last summer. Each year the National Oceanic and Atmospheric Association (NOAA) makes its predictions for the size of the dead zone and this year the bloom is expected to hit “near record” proportions.

An Ugly Forecast: As Earther reported,

  • An area the size of Massachusetts (approximately 7,829 square miles) could see an algae bloom that gobbles up oxygen and crowds out all aquatic life, creating an ecological and economic catastrophe.
  • Other forecasts range even higher, but all peg this as one of the worst dead zones ever recorded in the Gulf of Mexico largely due to the Midwest floods.
  • A tropical storm spinning up could help break up the dead zone and prevailing winds could push it around. But the volume of the low-oxygen zone itself is unlikely to change.

Why This Matters: We all rely on the food that farmers plant but farming practices are causing great environmental and economic (for say, fishermen in the Gulf) harm. Fortunately, practices exist to benefit both farmers and the environment such as using cover crops, reduced tillage, crop rotation, and nutrient management. One of the biggest barriers to making these practices more widespread is that they can be costly to implement and farmers need federal help to do so. Federal programs that exist to help farmers enact conservation farming practices and are wildly popular but significantly under-funded.

Make it a Campaign Issue: President Trump proposed sweeping cuts to these programs but some 2020 Democratic candidates see the immense value in expanded conservation farming. For instance, Gov. Jay Inslee has proposed the creation of “ARPA-AG” (similar in nature to ARPA-E, a government-funded research agency) to promote research into climate-smart agriculture under the Department of Agriculture as part of his $9 trillion Inslee compares his “Evergreen Economy” climate action plan.

Possible Lead Contamination in Water Problem Hits More Cities

Possible Lead Contamination in Water Problem Hits More Cities

New Orleans city officials, according to BuzzFeed News, buried a 2017 city Inspector General Report that showed that they had failed to test for lead in the water and they claimed that the City’s water was safe even though they were unable to locate the city’s many lead pipes — both of which they are required to do under the federal Safe Drinking Water Act.  And last week, water samples from 27 schools in Virginia Beach, Virginia were found to have levels of lead higher than industry safety recommendations.

Why This Matters:   Lead exposure is extremely bad for children.  According to the World Health Organization, children are “particularly vulnerable” to lead poisoning. Experts say that young children absorb 4-5 times more of the lead they ingest than adults, and high levels of lead in the bloodstream can adversely affect the development of their nervous systems and brains.

Investigation By Associated Press Reveals More Than 1600 Risky Dams in the U.S.

The results of a two-year investigation by the Associated Press (AP) were published this week and the findings were shocking — nearly 1,700 dams located in 44 states and Puerto Rico were rated as “high-hazard” dams that are in poor or unsatisfactory condition.  Experts believe the actual number of risky dams is even higher — […]

PFAS Found On Hundreds of Military Installations, With Numbers Likely To Rise

PFAS Found On Hundreds of Military Installations, With Numbers Likely To Rise

The problem of toxic fluorinated chemicals or “PFAS” is pervasive nationwide — and of the more than 1350 sites that have been identified by the Environmental Working Group (EWG) roughly half of them are on military installations, and the numbers are expected to rise once testing at Navy and Air Force installations is completed

Why This Matters:  Service members and their families did not sign up for this kind of preventable hazard when they joined the military — fighting in conflict is, of course, life-threatening, but simply living on a military installation should not be.  And the fact that President Trump has repeatedly threatened to veto any legislation that comes to his desk that requires the Environmental Protection Agency to regulate PFAS shows his callous disregard for the safety and well-being of our service members and their families.
