As fish stocks continue to shift and decline in response to overfishing and warming ocean waters, what types of seafood can one feel good about putting on the table?

Here's everything you need to know.

For nearly 50 years the Clean Water Act has made our waters safer for drinking, swimming, and fishing. But now, in a gift to corporate polluters, President Trump and his EPA administrator, Andrew Wheeler, have proposed new rules that would effectively dismantle the core of the Clean Water Act. This Dirty Water Rule would put us all in danger.

Last week, the U.S. Fish and Wildlife Service announced that it intends to strip gray wolves of Endangered Species Act protections and return wolf management to states that are eager to reinstitute hunting. “For over a hundred years, wolves have been needlessly persecuted,” says Bonnie Rice, director of the Sierra Club’s Greater Yellowstone/Northern Rockies campaign. “[They] have barely started to recover in some areas, and still occupy only five percent of their historic range.”

Trump’s EPA is proposing to make it easier to build more coal-fired power plants by rolling back carbon-pollution standards that protect the public health and welfare and are required by the Clean Air Act. Let the EPA know it must withdraw its unlawful proposal and instead commit to fully enforcing and strengthening the standards that are currently in place.

Detroit Outdoors, a collaboration between Sierra Club Outdoors for All, the YMCA, and the Detroit Parks and Recreation Department, has been turning kids on to nature right in their own backyards. “The coolest part is giving them the experience of camping and being able to do it [right here] in Detroit,” says youth leader Catie Bargerstock. "Some of them had never even heard of camping before."

"Our modern natural world is a house of cards in which every species plays a supporting role,” says award-winning science journalist Rachel Nuwer. "With each loss, no matter how big or small, something fundamental and unknowable shifts." Nuwer considers the importance of the Endangered Species Act in a photo essay featuring extraordinary pictures by longtime National Geographic contributor Joel Sartore.

The Golden State is a leader in reducing demand for fossil fuels—except when it comes to oil drilling. But a new movement is calling on California, the nation’s third-largest oil-producing state, to retire its oilfields.

Read more about California's history of oil drilling and the push to discontinue oil production in favor of green jobs.

In Episode 5 of the Sierra Club's podcast, The Overstory, we talk with author-activist Paul Hawken about his new book, Drawdown, and why he thinks that global warming may be a blessing instead of a curse. Then we take you to Acadia National Park in Maine, where National Park Service biologists are experimenting with "assisted migration" to help tree species cope with climate change.

Former New York City mayor and “this-dude-totally-gets-it-on-climate” philanthropist Michael Bloomberg announced this week that he would not run for president in 2020 but would instead focus on fighting climate change and moving the United States to 100% clean energy—including weaning the U.S. off coal by 2030. A remarkable run of victories for the climate and clean energy over the past few weeks suggests there’s good reason to believe it’ll get done.

Zion National Park turns 100 this year, hot on the heels of neighboring Grand Canyon National Park, which celebrated its centennial last month. Team Sierra didn’t want to miss out on the celebration, so last week a group of teammates participated in the Zion Centennial Half Marathon. Money raised by Team Sierra athletes helps preserve public lands, protect vulnerable places, and make the outdoors more accessible to everyone.

Find out how much they raised, and check out their photos of the half marathon.

Translation: "Let's Get to Work!" That's what Sierra Club associate communications director Javier Sierra has to say about the Nuevo Pacto Verde, “un atrevido plan de inversiones masivas para llegar a un 100% de energía limpia y renovable que nos libre de la amenaza climática.

“We Latinos have been waiting for the Green New Deal for decades,” Sierra says. “Let’s get to work!”
