RALEIGH, N.C. -- Health experts worldwide are warning that breathing polluted air can worsen and even cause high blood pressure, diabetes and respiratory diseases -- and early evidence suggests these conditions put people at higher risk for severe COVID-19 illness.

In a recent study, Chinese researchers found higher air pollution levels were linked to larger numbers of people hospitalized with pneumonia.

In addition to ozone pollution, which is odorless and invisible, atmospheric scientist Brian Magi, an associate professor in the Department of Geography and Earth Sciences at the University of North Carolina at Charlotte, said cities produce massive amounts of fine particulate matter.

"There's a lot of work being done to try to understand the very diverse set of pollutants within an urban space," he said, "almost to the point that there's divergence in the field of air-quality science, to begin to kind of think about the urban space as a unique piece of chemistry in our world."

Magi said tiny pollutants become lodged in the lungs, increasing the risk of respiratory tract infections from viruses. One 2003 study found that people with SARS were 84% more likely to succumb to that virus if they lived in regions with moderate air-pollution levels.

With the near shutdown of the global economy and sharp reduction in air travel, satellite imagery is showing air pollution has dipped. When the pandemic eventually ends, Magi said, taking steps to keep the air clean will pay off in the long run.

"Every little bit of air pollution that we keep out of the air and out of our human bodies will generate a public health impact that is measurable down the line," Magi said.

According to the World Health Organization, breathing polluted air prematurely kills more than 4 million people across the globe each year.

A North Dakota task force meets again next month as it considers updating the scope of local zoning laws dealing with factory farms.

It is an issue weighing heavily on the minds of community members who have fought such projects. The task force is expected to submit a proposal to state lawmakers before next year's legislative session.

The main focus is setback ordinances determining where a large animal feeding operation can go. State leaders have been vocal about the need for North Dakota to expand its livestock output and keep pace with neighboring states.

Lois Steinhaus, who lives near Devils Lake, said if a rural area has second thoughts, residents can feel overwhelmed.

"I feel on the edge a lot of the time," Steinhaus observed. "It's not like we hate the smell of farms. We don't, we're comfortable with that, but there's a difference between a herd of cattle and a barn that's got thousands of animals inside."

Steinhaus and her husband were part of a contingent pushing back against a proposed large-scale hog farm amid concerns about the effect on air and water quality, which led to a lengthy court battle. Even though project activity is quiet for now, the couple worries about future legislative moves. Agriculture officials contended there is not enough consistency and clarity under the patchwork of zoning laws.

Supporters of adding more animal agriculture in North Dakota tout the potential economic benefits.

Clark Steinhaus, chair of the Pelican Township's board of supervisors, said a key concern is location. He pointed out Devils Lake, the largest body of natural water in the state, would have seen its tourism drawing power evaporate if the project had moved forward without opposition.

"They were very close to the shores of Devil's Lake, and we have a lot of campgrounds around here," Steinhaus explained.

While the project in their backyard is essentially stalled, other proposals are surfacing, including plans for mega-dairy farms in eastern North Dakota.

The Steinhauses advised smaller communities exploring their options to prepare for things such as legal expenses, as well as the need to raise awareness through local media. They said it can help residents learn more and decide whether a project is right for their town. The next zoning task force meeting is Oct. 25.

Communities in Colorado and across the U.S. are making time to connect with nature during Hispanic Heritage Month.
Hilda Berganza, climate manager with the Hispanic Access Foundation, said last week's Latino Conservation Week saw thousands of people gathering at over 300 events. That's up from just nine events held during the initiative's launch in 2014.

"It was born from a commitment to Latinos being exposed to the outdoors. To experience being and playing in public lands, to empower families and future generations to be stewards of the planet, of the land," Berganza said.

Families of color are three times more likely than white families to live in areas considered concrete jungles without access to parks and natural areas. Due to policies some people deem racist, including redlining neighborhoods, communities of color also disproportionately live near high levels of toxic air and water pollution.

In 2022, just over 10% of Latinos were able to participate in outdoor recreation activities. Berganza said a broad coalition of community groups, nonprofits and faith-based organizations are working to change that. They are inviting families to picnics and park clean-ups, to go kayaking and hiking, to join scavenger hunts and festivals, and attend film screenings and webinars on the importance of maintaining healthy ecosystems.

"We also have events at churches where community members are learning why it's important to take care of our earth from a religious and spiritual point of view," Berganza added.

Berganza said work is also being done to push towns and cities to create parks and other green spaces in historically under-invested neighborhoods.

"National parks, or state parks, or even regular parks. They are not usually around or built within the communities that Latinos live in," Berganza said.

A new report warned climate goals in Georgia and nationwide are threatened by the rapid growth of industries like data centers and electric vehicles.

Clean energy advocates said utilities are extending coal plant operations and planning new natural gas facilities to meet rising energy demands.

Laurie Williams, director of the Beyond Coal Campaign for the Sierra Club and the report's co-author, noted while companies set ambitious climate goals, utilities remain reliant on fossil fuels.

"As just one example, in late 2023, Georgia Power reported a 20% jump in expected electric demand, largely due to new data center interconnections," Williams pointed out.

She added Georgia Power later filed an emergency resource plan, citing rapid load growth as the reason for extending a coal plant's life span and adding new natural gas capacity. Williams stressed while clean energy can take center stage, it requires action from customers, regulators and advocates alike.

The report outlined 12 recommendations for tackling energy demands while reducing emissions and keeping costs sustainable.

Jeremy Fisher, principal adviser on Climate and Energy for the Sierra Club and co-author of the report, said one of them pointed to the importance of collaboration.

"A little bit can go a long way," Fisher emphasized. "We recommend that utilities and large customers work together to maximize demand response management capabilities."

The report's recommendations also included comprehensive utility decarbonization plans and 24/7 clean energy sourcing and transitioning backup generators to batteries. There is also a strong call for advocates and large companies to push for stronger clean energy standards at the state and federal levels.
