This weekend bicycles are ruling the road in Yellowstone National Park. Most park roads are closed until later this month, but every spring Yellowstone opens about 50 miles of its main thoroughfares to bikes only.

Humans have long looked to animals for design inspiration. From basic camouflage to a quiet bullet train in Japan to the Wright brothers' wings, the process called biomimicry is a basic tenet of human engineering.

Jonathon Keats has turned it on its head.

For the second consecutive year, Japanese whalers have returned to port after an Antarctic expedition with the carcasses of 333 whales. The five-ship fleet, put forth by the country's Fisheries Agency, killed the minke whales during a months-long voyage to southern waters for what it calls ecological research.

River Revitalization Foundation is a nonprofit headquartered in what originally was a brick ranch along the Milwaukee River, upstream from downtown Milwaukee. Surrounded by restored shoreline, the south-facing portion of the building’s roof will soon be topped with ten solar panels.

That’s if Mike Ballo achieves his goal to raise $10,567 to install the panels. The panels themselves were donated to the foundation.

As California water officials confirmed Thursday that the snowpack in the Sierra Nevada remains well above average, pressure was mounting on the state to lift emergency water restrictions that have been in place for two years.

The snowpack across the mountains is now 164 percent of average, a closely watched marker in the nation's most populous state — and biggest economy — where one-third of all the drinking water comes from snow-fed reservoirs.

Driving up the coast toward Bay Center, Wash., it's obvious when you start to approach Willapa Bay. Fifteen-foot high piles of empty shells begin to appear on the side of the road. This is an oyster town.

But it's also home to a sinking piece of history.

When President Trump signed an order to roll back climate policies, he promised more jobs for coal miners.

"My administration is putting an end to the war on coal. Gonna have clean coal, really clean coal," Trump said in making the announcement at the Environmental Protection Agency headquarters Tuesday.

After millions of dollars of flood damage and mass evacuations this year, California is grappling with how to update its aging flood infrastructure. Some say a natural approach might be part of the answer.

All the water that poured down spillways at the Oroville Dam in northern California did a lot of damage to the area — and for miles down the river.

"It looks like a bomb's gone off," says John Carlon of River Partners, a nonprofit that does river restoration. "That's what it looks like."

Update 7:06 P.M. Eastern: The EPA says it's reversing course and keeping chlorpyrifos on the market.

That's despite the agency's earlier conclusion, reached during the Obama administration, that this pesticide could pose risks to consumers. It's a signal that toxic chemicals will face less restrictive regulation by the Trump administration.

The Great Lakes Restoration Initiative came to life during the Obama Administration, but it's seed was planted during George W. Bush's tenure.  And, now President Trump's budget calls for defunding the program.
