HARRISBURG, Pa. – Two dozen students held class in canoes Monday to learn first-hand the importance of clean water. It was the opening day of the Chesapeake Bay Foundation's fall 2017 Susquehanna Watershed Environmental Education Program, or SWEEP.

Students from the Steelton High School Science Club took to the waters of the Susquehanna River near Harrisburg to observe insects and aquatic life, test water quality and study the impact of human activity on the water.

Ryan McGrady, a co-manager of the program, says the experience gives the kids a real sense of the role they play in the environment.

"Students get that bright twinkle in their eye once they do come out with us, and you really see the light bulb go off on, 'This is what's in my backyard and this is how I can impact our ecosystem,'" he says.

Now in its 27th year, the SWEEP team will work with 19 regional groups in 11 counties, helping students build critical connections to the natural world.

McGrady points out that those connections extend beyond the lakeshores and river banks to adjacent land, the source of many of the pollutants that affect the river.

"We point out where farmers' lands may be right up against the water and those nitrates and manure may be flowing directly into that water," he explains. "We often look at just how the city roads are sitting right along the water, particularly in the winter and spring when a lot of that salt gets into the water."

The Susquehanna watershed is a major contributor to nitrate and sediment pollution flowing into the Chesapeake Bay.

Beyond the science, McGrady hopes the students who participate in the program learn that, from the headwaters in New York to the Chesapeake Bay, the Susquehanna is a living ecosystem.

"The importance and health of the river is something we can all play a part in our daily lives because we all live around the bay and everything we do up here affects somebody else downstream," he explains.

Amid U.S. Forest Service firings and layoffs by the Trump administration, conservationists are honoring a former employee this week considered by many to be the "father of wildlife ecology." Aldo Leopold was a supervisor of New Mexico's Carson National Forest before his eventual relocation to Wisconsin.

Each year a foundation named in his honor hosts "Leopold Week" -- a three-day event featuring acclaimed authors who, like Leopold, write about the natural world.

Richard Rubin, former New Mexico medical doctor and Forest Service volunteer, has seen firsthand the importance of forest management.

"The local Forest Service people are really devoted; a lot of good people doing the best they can," Rubin explained. "It's been tough work. Even before all these firings, the Carson Forest had 40% open positions they couldn't fill."

New Mexico's federal lawmakers have spoken out about the Trump administration's firing of federal workers, including the state's 2,200 federal employees in probationary periods. In addition to the Forest Service, those agencies include the Veterans Health Administration, the Bureau of Land Management and the Federal Bureau of Investigation, among others.

Rubin volunteered with others to help restore Leopold's craftsman bungalow in Tres Piedras, N.M., which became a national historic site in 1993.

"So the status of the place became significant then, and then completely restored in 2005-06, to the original appearance as Aldo built it," he explained.

Leopold wrote several books over the course of his life, but Rubin favors a quote from his most well-known -- "A Sand County Almanac," published in 1949: "That the situation is hopeless should not prevent us from doing our best."

In addition to his writings, Leopold is credited with the idea to create a protected area on the Gila National Forest in southern New Mexico, which was 100 years old in 2024.

New legislation would help build more wildlife crossings across Oregon highways to make roads safer for people and animals.

Research shows that Oregon has the highest likelihood of wildlife crashes among West Coast states, with nearly 5,000 damaging or deadly collisions in 2022.

Wildlife collisions are costly and dangerous for drivers and take their toll on wildlife as well.

New legislation would help build more wildlife crossings across Oregon highways to make roads safer for people and animals.

Research shows that Oregon has the highest likelihood of wildlife crashes among West Coast states, with nearly 5,000 damaging or deadly collisions in 2022.

The Oregon Department of Fish and Wildlife estimates that nearly 15 million animals are killed on Oregon's roads each year.

Karl J. Findling is on the board for the Oregon Backcountry Hunters and Anglers. He said it is time for Oregon to do more to address the problem.

"Oregon is behind nearly all Western states, with only five and a potentially new sixth crossing," said Findling, "where some states such as Colorado have 50."

Crossings have been shown to significantly reduce wildlife collisions. For example, an underpass near Bend cut them by more than 85%.

Findling said that along with driving population declines in many species, when you factor in medical and vehicle repair costs, collisions with wildlife are pricey.

"I've seen numbers around $7,000 per collision with a deer," said Findling, "but what's striking is $73,000 when someone hits an elk."

Although polls show wildlife crossings have broad, bipartisan support across the state, Findling said funding wildlife crossings remains a challenge due to high costs.

But, said Findling, with all the money they save, crossings pay for themselves within 15 years.

"When we see these crossings go in," said Findling, "the returns are close to $3 for every dollar invested."

Concerns are growing in Ohio over the use of oil and gas waste for dust control on rural roads, a practice some environmental groups argued is exposing communities to radioactive materials without their knowledge.

An informational symposium is coming up at the Ohio Statehouse March 6, featuring experts and activists discussing the potential risks.

Anton Krieger, symposium organizer for the Buckeye Environmental Network, said the event aims to raise awareness among lawmakers and the public.

"It's a public education campaign," Krieger explained. "We're willing to work with everybody. They may not even know the full health ramifications of oil and gas waste brine. They may not even know that they're being exposed themselves. We're going to be educating our legislators about why radioactive waste doesn't belong on our roadways in Ohio."

Current Ohio law allows brine from oil and gas drilling to be used as a dust suppressant on roads. Supporters argued regulated brine application is practical and cost-effective, particularly for rural areas with unpaved roads. However, environmental advocates said state testing has shown the waste contains radioactive elements, raising concerns about long-term exposure.

Roxanne Groff, a former Athens County commissioner and longtime environmental advocate, thinks many people are unaware of what is being spread on their roads.

"It's radioactive. It's radioactive. It's radioactive. And the State of Ohio knows this," Groff asserted. "They admit it. They've tested it. They've said it's radioactive."

The Ohio Department of Natural Resources, which oversees oil and gas waste regulations, maintains its brine management policies align with state law. The agency has said it continues to review environmental and public health concerns while working within legislative directives.
