[EX Q]: Paragraph: A recent count found 350 million purple sea urchins on one Oregon reef alone — more than a 10,000% increase since 2014. And in Northern California, 90% of the giant bull kelp forests have been devoured by the urchins, perhaps never to return. Vast “urchin barrens” — stretches of denuded seafloor dotted with nothing but hundreds of the spiny orbs — have spread to coastal Oregon, where kelp forests were once so thick it was impossible to navigate some areas by boat. The underwater annihilation is killing off important fisheries for red abalone and red sea urchins and creating such havoc that scientists in California are partnering with a private business to collect the over-abundant purple urchins and “ranch” them in a controlled environment for ultimate sale to a global seafood market. “We’re in uncharted territory,” said Scott Groth, a shellfish scientist with the Oregon Department of Fish and Wildlife. “You can’t just go out and smash them. There’s too many. I don’t know what we can do.” The explosion of purple sea urchins is the latest symptom of a Pacific Northwest marine ecosystem that’s out of whack. Kelp has been struggling because of warmer-than-usual waters in the Pacific Ocean. And, in 2013, a mysterious disease began wiping out tens of millions of starfish, including a species called the sunflower sea star that is the only real predator of the ultra-hardy purple urchin. Around the same time, the purple urchins had two excellent breeding years — and with no predators, those gametes grew up and are now eating everything in sight. “You can imagine all of these small urchins growing up, each one of them looking for food, desperate for food. They’re literally starving out there,” said Steven Rumrill, lead shellfish expert at Oregon’s wildlife agency. “I’ve seen some big-scale fluctuations in the populations of sea stars and urchins, but never on this magnitude.” Scientists are not yet sure if climate change is responsible for the sea urchin explosion, but they suspect it plays a role in the cascade of events that allowed the purple urchins to boom. And kelp, already under siege from warming waters, is not as resilient as it once was, said Norah Eddy, an associate director at the Nature Conservancy California’s oceans program. “We’re going to see climate change as a big driver of changes in kelp forest as we move forward, and we are already seeing that,” said Eddy, who is leading an effort to use drones to map and monitor Northern California’s last remaining kelp forests. The devastation is also economic: Until now, red abalone and red sea urchins, a larger and meatier species of urchin, supported a thriving commercial fishery in both states. But 96% of red abalone have disappeared from California’s northern coast as the number of purple sea urchins increased six fold, according to a study released this week by the University of California, Davis. Last year, California closed its red abalone fishery, which poured an estimated $44 million into the coastal economy per year, and Oregon suspended permits for its 300 abalone divers for three years. The commercial harvest of red sea urchins in California and Oregon also has taken a massive hit. “That’s a huge economic loss for our small coastal communities,” said Cynthia Catton, a research associate with the University of California, Davis Bodega Marine Lab. “In California, there were 30,000 to 40,000 participants in (the abalone) fishery every year for decades, and for the first time ever that fishery had to close.” And while the purple urchins have eaten themselves into starvation as well, unlike other kelp-dependent creatures, the species can go into a dormant state, stop reproducing and live for years with no food. That means the only way to restore the kelp is to remove or destroy the purple urchins. Scientists estimate that in Oregon alone, it would take 15 to 20 years to remove all 100 million pounds (45 million kilograms) of purple urchins recently surveyed on just one large reef. While urchins are in starvation mode, the edible part — known as roe — shrivels, making them commercially worthless. Against this backdrop, conservationists, commercial urchin harvesters, scientists and private interests are coming together with an unusual plan: Pay underemployed red sea urchin divers to collect the shriveled, but living, purple sea urchins and transfer them to carefully tended urchin “ranches” to be fattened up for sale to seafood markets around the world. One company, Urchinomics, is already working on urchin ranching projects in Japan, Canada and California and sees a future where the overwhelming demand for wild urchin roe is replaced by a taste for human-raised purple urchins collected from the seafloor, allowing kelp forests to rebound. “We’re turning an ecological problem into an ecological opportunity and an economic opportunity,” said Brian Takeda, the Urchinomics CEO. “It’s the first time we’ve ever had an economic incentive to get these destructive urchins out of the water.” In Oregon, red urchin divers are a tiny artisanal collective, but they are also exploring ways to try to turn the glut of destructive purple urchins to their advantage. Oregon’s urchin fishery had a boom year last year, when red urchins were scarce in California but before their purple cousins had spread north. Now, they too are hurting. Rumrill, the shellfish expert from Oregon, supports efforts to harvest excess urchins but strikes a less optimistic note when it comes to saving the kelp. “That’s a promising technique. But we shouldn’t fool ourselves into thinking that we’re going to solve this large-scale ecological problem, this literal perfect storm of events, by eating our way out,” he said. “It’s just too big a problem.” ___ Chea reported from Mendocino County, California. ___ Follow Gillian Flaccus on Twitter at http://www.twitter.com/gflaccus .

[EX A]: Tens of millions of voracious purple sea urchins that have already chomped their way through towering underwater kelp forests in California are spreading north to Oregon, sending the delicate marine ecosystem off the shore into such disarray that other critical species are starving to death.

[EX Q]: Paragraph: “Independents need to know they can invest their vote in the Democratic Party,” Carter said Tuesday during his annual report at his post-presidential center and library in Atlanta, where he offered caution about the political consequences should Democrats “move to a very liberal program, like universal health care.” That’s delicate — and, Carter admitted, even contradictory — advice coming from the 93-year-old former president, and it underscores the complicated political calculations for Democrats as they prepare for the November midterms and look ahead to the 2020 presidential election. “Rosie and I voted for Bernie Sanders in the past,” Carter noted. He was referring to his wife, Rosalynn, and their support for the Vermont senator, an independent who identifies as a democratic socialist, over establishment favorite Hillary Clinton in the 2016 Democratic presidential primary. At another point, he pointed to California’s environmental policies — limits on carbon emissions, stiffer fuel-efficiency standards — as the model for combating climate change. Still, Carter stressed, Democrats nationally must “appeal to independents” who are souring on the current administration. Trump’s job approval rating, according to Gallup, has dipped to 40 percent, mostly because of declining support among independents. Carter alluded to arguments from self-identified progressives that Democrats will sacrifice votes on the left if they don’t embrace the liberal base: “I don’t think any Democrat is going to vote against a Democratic nominee,” and he insisted that he’s not asking the left to sacrifice its goals, only to see that winning elections is necessary to accomplish any of them. There is some historical irony in Carter’s analysis. He came to the White House in 1976 from the moderate wing of the Democratic Party, and he clashed with party liberals, drawing a spirited primary challenge in 1980 from Massachusetts Sen. Ted Kennedy. Carter prevailed, but he was wounded, abandoned by Kennedy’s most liberal supporters and unable to win over independents who helped deliver a landslide for Republican Ronald Reagan. Carter’s latest handicapping comes near the conclusion of a midterm primary season that has seen Democratic primary voters move the party to the left. In some states and districts, that means nominating full-throated advocates of single-payer health care, a $15 minimum wage and abolishing or at least overhauling the federal Immigration and Customs Enforcement agency. In other races, it means nominees who back more cautious moves to the left, such as background checks before certain gun purchases, a “public option” health insurance plan to compete alongside private insurance policies, step raises for the minimum wage and an immigration overhaul that offers legal status to some immigrants in the country illegally. Carter did not delve into those distinctions, instead offering a sweeping condemnation of his latest successor to remind Democrats of the stakes. He denounced the administration’s latest environmental policy proposal to make it easier for energy companies to release methane gas that contributes to climate change. He singled out Trump’s policy of separating immigrant families at the border, including those seeking asylum. “America is inherently committed to human rights, and I think in the future we will let that prevail,” Carter said, “but for the next two years, I can’t predict the imprisoned children are going to be any better off — unfortunately.” Carter has previously criticized Trump for his repeated falsehoods, and he’s chided Trump for his hardline support for Israel over Palestinians. Yet Carter has found common ground with Trump on other foreign policy fronts, and did so again Tuesday. While avoiding any mention of the special counsel’s investigation into whether Trump’s presidential campaign coordinated with Russia in the 2016 U.S. election, Carter said he has engaged for years with Russian President Vladimir Putin concerning the ongoing Syrian civil war. “I have his email address,” Carter said, adding that he and Putin share the same Russian river as their favorite spot for salmon fishing. That friendship, Carter said, means when Russia and other nations hold multilateral talks about the Syrian conflict, “Quite often they invite the Carter Center. ... They do not invite the U.S. government.” Carter also praised Trump for meeting with North Korean leader Kim Jong Un. Carter repeated his frustrations with the last Democratic president, Barack Obama, for not engaging more directly with the insular Asian nation. Carter said he’s not sure Trump has made real progress yet with North Korea, but he endorsed calls for the U.S. to formally declare an end to the Korean War and normalize relations with Pyongyang. “Let them be part of the community of nations,” he said. “I think that would be enough in itself to bring an end to the nuclear program in North Korea.” ___ Follow Barrow on Twitter at https://twitter.com/BillBarrowAP Claim: Jimmy Carter: To beat Trump, Dems cannot scare off moderates.
