AMARILLO, Texas – A new report examines how the expansion of cropland in Texas and other states under the federal ethanol mandate has contributed to climate-change pollution. The mandate originally was enacted to cut energy imports, reduce pollution and lower fuel costs.

But Collin O'Mara, president, and CEO of the National Wildlife Federation, says in addition to generating pollution, the measure has caused the loss of millions of acres of uncultivated land.

"In the years following enactment of the mandate in 2007, more than 7 million acres of wildlife habitat were plowed under," he says. "This is grasslands and wetlands and other habitat that threatens monarch butterflies, bees, ducks and other wildlife."

The report, produced by the University of Wisconsin, ranks Texas second in the nation for its release of more than 2.7 million metric tons of carbon. Across the country, the ethanol mandate has caused the release of 115 million metric tons of carbon, the pollution equivalent of putting 20 million more cars on the road each year.

Seth Spawn, the lead author of the report, says cropland expansion, no matter the cause, is having profound impacts on the land and the carbon that it holds.

"For so long, we've heard about the importance of tropical rain forests as an important carbon reserve, this research shows now is the time to also recognize the importance of the less charismatic carbon reserves here at home," he explains.

O'Mara says the ethanol mandate has not lived up to its original goals.

"These findings should serve as a wake-up call to all elected officials and EPA administrator Pruitt that it's time to that we have to act with purpose and urgency to fix the ethanol mandate and to confront climate change to protect our health, our environment, our economy and wildlife," O'Mara adds. "Delay is only going to make the problem worse."

He says after initially announcing plans to scale back the ethanol mandate, the EPA recently did an about-face and set the 2018 standard at or above current levels.

New research from the University of New Hampshire could help dairy farmers increase profits while reducing their effect on the climate.

Scientists said adding a plant-based essential oil blend to cow feed can improve a cow's digestion and reduce the release of methane, a potent greenhouse gas.

Andre Brito, associate professor of dairy cattle nutrition and management at the University of New Hampshire, said the findings are especially true for pasture grazing cows and shows a happy cow makes for a healthier environment.

"If those animals are provided those conditions, they'll be more productive," Brito pointed out. "Then the amount of methane that's being emitted by those animals is diluted because they're producing more product."

Brito reported adding the plant oils led to a more than 6% increase in milk production, which is good news for the majority of New Hampshire dairies, especially small to mid-size operations with smaller profit margins and higher equipment costs.

Still, Brito noted the research findings could translate to larger, industrial-size dairies. The factory farms often hold thousands of cows, generating significant methane emissions through their hearty burps and manure, which is often stored in large, polluting lagoons.

Brito acknowledged although the plant-based oils are readily available for use, farmers must weigh the economic benefits and overall environmental impact.

"Any investment that the farmers would make in a product has to be tied to economics," Brito stressed. "Even though farmers overall, they are conscious about the environment and they want to make sure that there is less carbon, nitrogen footprint out of their farms."

Brito's research was conducted on cows as they transitioned from the winter indoor-feeding schedule to eating their favorite plants in the pasture, a diet change which can increase the cow's emissions.

Brito added he hopes the research can help farmers better understand when to add the oils to the cow feed to potentially reduce the cow's overall climate effect.

State officials in Maine are highlighting apprenticeships as a way to earn a living wage and contribute to the state's growing green economy.

They'll kick off the first-ever Youth Apprenticeship Week by exposing high school students to the numerous ways they can learn and earn in offshore wind energy development, passive home construction, aquaculture, and more.

Maine Department of Labor Apprenticeship Program Manager Kristine McCallister said about 90% of apprentices choose to stay with their employer after their training is complete.

"Apprentices have a mentor and they're earning wages and they're earning pay increases as they go," said McCallister, "so it's a really great way to attract talent to Maine and to keep talent here."

McCallister said apprentices will earn $300,000 more over their lifetime. The state aims to add 75,000 more workers to the economy over the next five years by growing career training pipelines.

A report by the Maine Labor Climate Council finds the state can create tens of thousands of jobs by building a zero-carbon transportation system.

Workers will be needed to install EV charging stations, electrify school bus fleets, and potentially build a high-speed rail line from Bangor to Boston.

McCallister said new Mainers, like those studying with Portland Adult Education, are using apprenticeships to fill these roles and other clean-energy jobs.

"Those pre-apprentices just graduated and have interviewed with some of our apprenticeship programs," said McCallister, "so we're really hoping they're going to help feed that pipeline as this economy is booming in Maine in terms of the renewable-energy sector."

McCallister said some companies are even offering on-the-spot interviews and job offers this week. All apprenticeship events are listed on the Department of Labor's website.

Climate watchers are predicting this summer's temperatures may set records, which could aggravate some medical conditions.

A 30-year study of health records from more than 200 countries and territories suggests a connection between stroke and climate change. The online publication "Neurology" reported the growing number of global deaths and disabilities from strokes are linked to -- but not caused by -- climate change.

Dr. Ann Jones, stroke neurologist at Indiana University Hospital, said when the body feels extreme heat and sweat evaporates, hypercoagulation, or blood thickening, occurs, which increases the chance for blood clots. Winter weather can also produce an instinctive response.

"The cold makes us kind of react with our fight-or-flight kind of drive, and it makes our blood vessels close down or vasoconstrict," Jones explained. "That can raise blood pressure up and that can predispose you to stroke."

Jones noted an ischemic stroke involves a clogged artery preventing blood from flowing to brain tissue. A ruptured artery during a hemorrhagic stroke causes blood to travel outside the artery wall into the brain tissue.

The Centers for Disease Control and Prevention reported almost 43% or 3,500 per 100,000 Hoosiers died from a stroke in 2021. Indiana ranks 34th in the nation for the rate of strokes.

The Yale Center on Climate Change and Health found heat can increase the risk of a stroke. Recent global burden-of-disease studies found 2 to 5 million deaths per year are linked to extreme temperatures globally. And climate change can also indirectly impact health through poor water quality, air pollution and increased spreading of infectious diseases.

Jones maintained good health is a start toward prevention and recommends the Mediterranean diet; consuming less red meat for optimal well-being and getting 30 minutes of exercise five times per week.

"Some things are out of our control," Jones acknowledged. "But just taking care of yourself in the ways that we can; focusing more on vegetables, fish, and staying hydrated, working on blood pressure with that reduced goal of less than 130 over 80."

The study indicated more research could identify the impact of temperature change on stroke as a way to address health inequalities including the burning of fossil fuels, deforestation and industrial processes.
