In 2011, the National Park Service put in place a policy to encourage national parks to end the sale of bottled water. The aim was to cut back on plastic litter.

It was not actually an outright ban — but 23 out of 417 national parks, including Grand Canyon National Park and Zion National Park, implemented restrictions on bottled water sales. The parks encourage visitors to use tap water and refillable bottles instead.

Now, The Trump administration has reversed this Obama-era policy.

When was the last time you used the entire container of fresh herbs you bought at the store? Never? Me, too. Every time a recipe calls for 1-2 tablespoons of freshly chopped sprigs, I head to a supermarket and reach for a plastic container holding at least three times as much as I need. A few days later, I'm standing by the trash can observing a moment of silence before I discard a plastic coffin of wasted, withered basil.

Spectators around the country are gearing up, eclipse glasses at the ready, for the solar eclipse on Monday. But another group — perhaps more anxious than eager — is preparing as well: the people who run California's electric grid.

California is home to almost half of all the solar power in the country. So even a partial loss of the sun will mean a major dip in the energy supply.

President Trump's astonishing press conference on Tuesday was, ostensibly, an announcement about infrastructure. But his brief remarks on the permitting process were entirely overshadowed by his defense of attendees at a white supremacist rally, among other remarks.

The dangerous blue-green algae in Milwaukee's Veterans Park lagoon continues to pose a risk to human and animal health. Last weekend, organizers of a dragon boat festival moved the event elsewhere because of toxins created by the algae. And this coming weekend, water skiers had planned to compete in a two-day competition.

The water ski event was canceled Wednesday, due to the water's condition.

As a substitute for coveted elephant ivory, mammoth tusks can sell for hundreds of thousands of dollars. A rush is underway to dig them out of the frozen earth in Siberia and sell them, mostly to China. The hunt is making millionaires of some men living in this impoverished region — but it's also illegal.

Photographer Amos Chapple followed a group of tusk hunters in Siberia on assignment for Radio Free Europe/Radio Liberty. He recalled his three-week journey with NPR's Ailsa Chang.

Can We Feed The World With Farmed Fish?

Aug 15, 2017

For years, scientists and activists have sounded the alarm that humans' appetite for seafood is outpacing what fishermen can sustainably catch.

But new research suggests there is space on the open ocean for farming essentially all the seafood humans can eat. A team of scientists led by Rebecca Gentry, of the University of California, Santa Barbara, found that widescale aquaculture utilizing much of the ocean's coastal waters could outproduce the global demand for seafood by a staggering 100 times.

If, for some reason, you find yourself in a situation where you need to wash radioactive material from your body, don't reach for the bottle of hair conditioner. Conditioner can bind radioactive particles to your hair.

This week, you can't reach me by email, or text, or Tweet.

This week, I'm not taking anyone's calls, either.

That's because I'm walking the Appalachian Trail — alone. And while I am, without doubt, scared of being eaten by a bear, I'll be out there looking for that most precious of possibilities: solitude.

More than two weeks after they were first spotted, wildfires on the western coast of Greenland are still burning, worrying local residents and drawing the attention of scientists.

The Trump administration has begun the process of rolling back tough fuel standards for America's car and light truck fleet.

The Environmental Protection Agency and the Transportation Department have opened the public comment period on the rewriting of standards for greenhouse gas emissions for cars and light trucks for model years 2022-2025.

In preparation for your next Taco Tuesday, dining critic Ann Christenson wrote the cover story on the best tacos in town in the August issue of Milwaukee Magazine. She explains that what we’re talking about here is tacos - not, strictly speaking, Mexican food.

"For better or worse, if you take a flour or corn tortilla and put some really delicious ingredients inside, wrap it up....it is a different form of sandwich," she explains.

The State Assembly Committee on Jobs and the Economy will vote Monday afternoon whether to give Foxconn $3 billion in incentives.

Supporters say the huge factory would result in thousands of jobs and a significant boost to the state’s economy. Critics say the bill comes at too high a price - in terms of dollars and its environmental impacts.
