The Trump administration is using its final weeks to push through dozens of environmental rollbacks that weaken protections for migratory birds, expand arctic drilling and increase future threats to public health.
One proposed change would restrict criminal prosecution for industries that cause the deaths of migratory birds. The Migratory Bird Treaty Act of 1918 currently protects over 1,000 species of bird including hawks and other birds of prey, and it is used to recover damages in situations like the BP oil spill in 2010 that killed more than 100,00 seabirds, according to an AP article. The Trump administrations wants to ensure that companies face no criminal liability for preventable deaths such as this in the future. Officials advanced bird treaty changes to the white house two days after news organizations declared Joe Biden’s win.
Another recent proposal put forth by the Trump administration would set emission standards for dangerous particles of pollution emitted by refineries and other industrial sources. Others would allow mining and drilling on public lands around the Chaco Canyon National Historical Park in New Mexico and in Alaska.
Most of these proposed changes directly benefit gas and oil industries, and some of them could be difficult for President-elect Joe Biden to reverse once he takes office. Biden could easily reverse some with executive action, but others, like putting protected lands up for sale or lease, could pose a bigger challenge.
Most of the proposed changes will go quickly through the approval process. It is not unusual for presidents to push rule changes through at the tail end of their terms, but many environmentalists and former officials believe this environmental deregulation reflects a pro-industry agenda taken to the extreme. It could have serious negative impacts on the safety of imperiled wildlife, climate change and human health.
Researchers created a non-invasive tool to sample environmental contaminates in honeybee hives.
Bees are good bioindicators of environmental contamination because they get coated with everything in their surroundings, including pollutants. Because they have a wide flight range and sample from a range of spaces, they can pick up build-up from the air, water, ground and trees. They also spread the nectar they collect to other bees and throughout the hive.
Researchers have used honeybee hives to understand the environmental contamination in their area in the past, but the process was often harmful. It involved capturing bees and extracting whatever they had ingested or transported on the surface of their bodies. Sampling could also be done with pollen reserves, larvae and honey. Not only was this often very difficult and time-consuming, it also often disrupted the normal functioning of hives, according to a PHYS.ORG article.
Professor José Manuel Flores, from the Department of Zoology at the University of Cordoba, collaborated with researchers at the University of Almeria to put a new device into operation. APIStrip (Absorb Pesticide In-Hive Strip) is a non-invasive polystyrene strip that is placed in a hive and can absorb a variety of pesticides and other pollutants for testing. This device will allow researchers to continue to use honeybees as sample collectors and improve environmental health without jeopardizing the safety of honeybee colonies.
The #BoycottBigMeat campaign launched Tuesday and calls for consumers to boycott meat products from large corporations.
Over 50 organizations are backing the campaign, including Iowa Sunrise Hub, Cedar Rapids, and Iowa Alliance for Responsible Agriculture. Those behind the effort cite a number of issues with large-scale meat producers including worker safety, animal welfare, consumer health and environmental impact, according to a Public News Service article.
While some groups involved in the campaign are focusing on holding corporations accountable for exploiting workers during the COVID-19 pandemic, others are hoping to confront longstanding issues with the negative impacts these businesses have on the environment. Feed sourcing is a leading cause of natural prairie loss in the Midwest, and the chemicals and fertilizers used to treat the fields that grow feed crops are polluting waterways, according to Clean Water Action. Large corporations are also responsible for huge carbon emissions that contribute to climate change.
“We really want to push for policy that helps to transform these rural communities where these operations exist – these industrial operations, meat-packing plants, as well as the concentrated animal feeding operations – that we want to help transition to a better food system,” said Sherri Dugger, executive director at the Socially Responsible Agricultural Project.
The coalition hopes that consumers and policymakers will help promote local producers who sell products considered organic and regenerative that come from pasture-raised, grass-fed animals.
April 22, 2020, is not just another Earth Day. It is the 50th anniversary of the first Earth Day – the one that changed my life forever. Naive and over my head as student body president at Iowa State-1970, my world was on fire with righteous indignation against a compulsory draft for an unjust War in Vietnam. At times I actually thought that it would tear the country apart.
The first Earth Day strangely diverted my immediate attention, and the diversion would last a lifetime. Brainchild of Senator Gaylord Nelson and organized by Denis Hayes as a national Teach-In, Earth Da
y spawned immense bipartisan gatherings of 20 million people in the streets for one unifying goal – a healthy Planet Earth. Earth Day ignited in me a realization that my chemical engineering education from ISU could morph into something green and more fascinating, that is, trying to understand water quality, biodiversity, and the biogeochemistry of Earth’s processes. Discerning remedies for the massive disruptions that 7.7 billion people and an $80 trillion GWP can inflict on the earth has proven even more challenging.
This year we celebrate Earth Day with digital gatherings due to coronavirus. It’s not the same, but perhaps the pandemic can teach us some valuable lessons. Some people were slow to accept the dismal science of a spreading pandemic – they lacked trust in health professionals’ recommendations for social distancing, staying home, and closing businesses, sporting events, churches and social gatherings. But the flattening curves of Wuhan, South Korea, Singapore, and even Italy, Spain, and New York bear testament to the wisdom of their call.
Our national plan for the pandemic Covid-19 was non-existent, like the Emperor’s new clothes, plain for all to see. Pandemics are “global disease outbreaks” and they require national plans and concerted global action. As recently as 2003-2004, WHO mitigated much more rapidly a similar virus, SARS, by careful messaging and international cooperation of 11 labs in 9 different countries. U.S. and Chinese scientists together developed a vaccine within a year. Far too little cooperation exists today, both at home and abroad. Politics and hyper partisanship are disastrous in a time of global need. We can do better.
Analogies between climate change and our pandemic response are obvious. We have no national plan for either. As a young egg-head professor at the University of Iowa, I published my first modeling paper on climate change and its consequences in 1994, many years after others had done so. It projected (surprisingly accurately) the concentration of carbon dioxide in the atmosphere today with business-as-usual. That’s exactly what happened – business as usual. If you had told me that the U.S. would still not have comprehensive climate change and energy legislation in 2020, I would have told you, “you’re crazy”.
But it’s in the history books. We have failed to listen to the science and failed to reduce our gargantuan greenhouse gas emissions — the planet cannot take it anymore. Now it really is a Climate Emergency. What’s more, we are threatening to extinct 1 million species in the next generation as well – the Biodiversity Crisis.
Coronavirus humbles us all. How can one not be moved by the sight of doctors, nurses, custodians, and admissions clerks risking their lives for the rest of us? How can one not weep to see the miles of cars lined-up at food banks because families have nowhere else to turn? Playing out in the richest country in the world gives great pause.
Yes, we need science-based decision making on coronavirus and on climate change, but we need compassion and understanding as well. Noted columnist Sarah Van Gelder writes, “Changing hearts and opening minds begins when we listen”. Imagine the world we want, where everyone is safe and healthy, where the air is clean and the water is pure. Then, let us celebrate the 50th Anniversary of that spontaneous, bipartisan, original Earth Day by speaking from the heart and listening to each other.

Forty-three deer killed by hunters and vehicles in Iowa during the 2019-2020 hunting season tested positive for chronic wasting disease, also known as “zombie deer disease.”
This brings the total number of confirmed cases in Iowa’s wild deer population to 89 since 2013, according to an Iowa Department of Natural Resources press release. That’s a 93% increase in one year.
Chronic wasting disease is a 100% fatal neurological disease found primarily in deer and elk that causes loss of bodily functions. An abnormal protein causes the infection, spread via bodily fluids from deer to deer. Some symptoms include excessive salivation, weight loss, listlessness and drooping ears and head.
The disease is in the same family as bovine spongiform encephalopathy, also known as Mad Cow Disease. The Centers for Disease Control reports that there is no conclusive evidence of the disease transferring to humans, but the center recommends avoiding contacts with infected venison.
The Iowa DNR collected samples from about 7,000 deer hunted or killed by cars across the state during the 2019-2020 hunting season. Samples from Woodbury, Winneshiek, Fayette and Decatur counties tested positive for the first time.
Officials have identified chronic wasting disease in wild deer populations in eight counties overall. Deer in several captive populations have tested positive as well (see this interactive map for more information).

A news story published last week featured an Iowa farmer who illegally built to un-permitted barns containing about 2,400 hogs. State officials were unaware of the concentrated animal feeding operations (CAFOs) for years.
That farmer and others are fighting in what Associated Press correspondent John Flesher called a “battleground” in Iowa. Questions of pollution and regulation have inspired lawsuits, anti-CAFO alliances and neighborly tensions throughout the state, as animal feeding operations continue to proliferate.
Below are four key takeaways from Flesher’s in-depth report. Read the full-length story on apnews.com.
The federal government relies state data for animal feeding operation data. In many cases, states keep tabs on only the largest operations (in Iowa, a true “CAFO” has a minimum of 1,000 species-variable “animal units” per confinement). The EPA counted about 20,300 CAFOs nationwide in 2018. The U.S. Department of Agriculture estimates there are about 450,000 animal feeding operations–places animals are raised in confinement (of any size)– nationwide.
Under the 1972 Clean Water Act, especially large livestock operations need permits for discharging waste into waterways. Since such discharges are often unintended, however, state and federal environmental agencies can only mandate permits for operations caught discharging waste. In some cases, farmers have been able to make spill-proofing improvements instead of applying for permits.
Studies show that livestock operations and anaerobically decomposing waste release massive amounts of ammonia and greenhouse gases. Because such emissions are difficult to measure, though, they are unregulated by the Clear Air Act. Studies have additionally correlated these emissions to human health issues such as childhood asthma. Cause/effect is impossible to prove, however.
The UI Center for Global and Regional Environmental Research is excited to announce the revival and reimagination of our EnvIowa podcast. This weekly podcast will feature 10- to 20-minute interviews with Iowa environmental experts, mainly our own member scientists.
While these researchers are certainly well versed in the complicated jargon of their disciplines, our interviews aim to make their ideas accessible to a general audience. Questions focus not only on the research itself, but how the experts believe it can be applied to solve environmental challenges.
Today’s installment features an interview recorded January 28 with Dr. Silvia Secchi, an interdisciplinary economist and geographer at the University of Iowa. Listen to learn more about Dr. Secchi’s fascinating research on human/environmental interactions in the Mississippi River watershed and how agriculture in particular plays a role within the larger system.
In the 1960s, giant tortoises from Espanola, a part of the Galapagos Islands, were placed on the endangered species list. In efforts to save the species, Diego, a young adult tortoise was placed into a breeding program. 15 other tortoises took part in the breeding program, but no one committed more to the cause then Diego. The species now has over 2,000 tortoises, about 1,700 of which are descendants of Diego.
Diego weighs 176 pounds and when he’s fully stretched out, stands at five feet tall. Mr. Carrion noted that there are some characteristics that made Diego “special” and more attractive to the opposite sex. As the species continue to procreate, tortoises will continue to look like Diego. A process called the bottleneck effect, where a survivor’s gene dominates the gene pool. While little genetic diversity can leave the species vulnerable to diseases or changes in habitat, Dr. Linda Cayot of the Galapagos Conservancy said that “every species came from a bottleneck.”
Last week, the zoo announced that nearing the 80th year he’s been gone, they will be retiring Diego and returning him to the Espanola islands.
“He’s contributed a large percentage to the lineage that we are returning to Espanola,” Jorge Carrion, the Galapagos National Parks service director, told AFP. “There’s a feeling of happiness to have the possibility of returning that tortoise to his natural state.”
New observational research has found that people with high exposure to common “pyrethroid” insencticides were 56% more likely to die during a study period than others. Cardiovascular disease was the leading cause of death in the exposed.
CGRER member Wei Bao, assistant professor of epidemiology in the University of Iowa College of Public Health, is an author of the study, published Jan. 30 inJAMA Internal Medicine.
Pyrethroid insecticides are used in most household insecticides and some pet products and head-lice shampoos. The study followed a sample of 2,116 adults who took the United States National Health and Nutrition Examination Survey between 1999 and 2002, representative of the U.S. population as a whole. The researchers noted levels of pyrethroid-associated chemicals in their urine and found death records to determine how many had died by 2015, as well as their cause of death.
While those with higher pyrethroid exposure were more likely to die overall, the highly exposed were three times more likely to suffer cardiovascular deaths than others as well. Bao said in an Iowa Now feature that the study does not prove that the insecticides are the cause of death, only that death and exposure are correlated.
