Tiny aquarium leads charge to heal coasts Cabrillo Marine Aquarium in San Pedro nurses endangered species to be reintroduced into wild

By Kim McGill The Cabrillo Marine Aquarium in San Pedro focuses on education, research and conservation to connect people to the underwater world of Southern California.

School visits, beach cleanups and interactive exhibits put people in contact with some of the region’s smallest aquatic species.

Despite the happy chaos, one section of the aquarium remained quiet—the aquatic nursery—where the gurgling of the huge cylinders “growing live foods” stretched to the ceiling could be heard.

The aquarium is using its nursery to raise criticallyendangered species that can be reintroduced to the wild, including the white abalone.

Native to Southern and Baja California, the marine snail was the first invertebrate on the endangered species list.

“A lot of the invertebrates found in the tide pools are taking the biggest hit,” Research and conservation curator Brenton Spies said.

The larvae being reared in the nursery exhibit how climate

change impacts marine life.

The aquarium researches how to properly intervene.

Other marine life rely on smaller animals for food. The destruction of the tide pools is altering the ecosystem, making algae dominant. Climate change, overdevelopment, severe weather and pollution has created a cycle that’s throwing off the ecological balance.

“Tide pools are getting filled in or deteriorating … That impacts a lot of the animals,” Spies said humans manipulate the coast.

Spies said development has dominated the coast, leaving little space for wildlife.

“For example, the barrier walls built to protect the cliffside homes are increasing erosion,” Spies said.

Instead of soaking into earth, the waves hit the walls and they bounce back stronger, increasing erosion.

El Camino student Glenys Rich has been working and volunteering at the aquarium for over three years.

Rich described how new currents bring pollution.

Sediment runoff from agriculture and the streets also poisons the

ecosystem. Erosion is shrinking the beaches.

“Climate change has affected a lot of the tide pools,” Rich said. “The water comes up too high, causing erosion that pulls away the sand on the beaches.”

Spies urges South Bay communities to become more active, get educated on climate change and eat sustainable seafood.

“Vote with the environment in mind,” Spies said. @KimMcGillLA

Climate change amplifies California’s coastal erosion Preventative measures needed to combat natural, human contributions to changing coastal climates

By Khoury Williams Most of California’s beaches could be washed away by 2100, according to a recent study from the United States Geological Survey.

The impact of coastal erosion, which refers to the soils, rocks and sands being carried away or worn down by changes in the climate, have worsened with climate change.

According to the California Coastal Commission, California’s beaches get visited more than 150 million times per year, making the ocean and coasts in California one of its most popular destinations for both tourists and local residents.

The Monterey Bay National Marine Sanctuary found 85% of California’s coasts are experiencing active erosion from human involvement and natural causes.

El Camino College’s earth sciences professor Sara Di Fiori said human interaction and misuse can contribute to the problem.

“All of these impacts and all of these collisions between the

Di Fiori added rising sea levels and rain storms also increase the “energy” that shapes its coastlines.

J.D.

Allen said coastal erosion can also worsen sewage, electricity and essential trading harbors that include access to fishing vessels and cargo ships. He noted that if people want to continue living and building along the coasts, they have to adapt.

“A lot of my podcasting work has been about climate adaptation,” Allen said. “If we want to continue to live somewhere, we have to figure out a way.” @williamskhoury

Sunken City’s dire coastal warning

What one tiny San Pedro neighborhood that slid into the sea can teach us about about the future Mother nature has a bigger budget

By Kim McGill Nearly 100 years ago, there was a neighborhood here.

Built by developer George Huntington Peck, 39 luxury homes were built on local cliffs overlooking the Pacific Ocean.

The final development of the elite San Pedro Hills.

But within a few years of opening, the land beneath the cliffs shifted, a water and gas line broke, the street cracked and dropped several feet.

By June 1929, the community had slumped over 7.5 feet. An earthquake in July hastened the movement further.

The community was evacuated. The area was renamed the Point Fermin Landslide.

In May of 1931, William M i l l e r, p r o f e s s o r a n d chairperson of the Department of Geology at the University of California, Los Angeles, published a study of the landslide in Scientific Monthly.

“A considerable body of bedrock is slowly moving into the sea,” he wrote.

Miller described the cause of the drop.

“Five acres of bedrock on land, as well as a larger portion of bedrock under the ocean, is breaking away from the mainland,” he wrote.

He added that the fissuring and cracking of the ground caused a number of buildings to be damaged.

“Where the ever-widening main fissure crosses the street, an attempt is being made to keep it filled with dirt,” he said.

But by the 1940s, all that was left was the crumbling foundations of the remaining two homes, now sitting more than fifty feet below from where they originated.

Miller’s report read that “the fundamental cause of the landslide lies in the character and structure of the rocks. It’s an anticline in a strong seaward dip likely to continue for years.”

A very dangerous area

26.3 million Californians live along the coast. Increasingly for these residents, the devastation of coastal erosion is becoming more evident.

From the rocky Bluff Cove beach on the Palos Verdes Peninsula, El Camino earth sciences professor Sara Di Fiori instructed her students to observe how erosion impacts the coastline. Close by the green and brown vegetation engulfing the cliff side was interrupted by a large section of

She says De Baca said. owners and developers also But developers’ quest to build make poor landscaping on every inch of the coast decisions.

“If you add water to clay, it swells up and if the layers are tilted toward the ocean, you slide right in,” Di Fiori adds.

For that reason, she says, the Tongva should be involved in every decision about development in LA County.

“Our indigenous elders remind us that the earth serves us, and we’re expected to serve the earth,” De Baca said.

Today, Sunken City is known worldwide as an essential destination for graffiti writers.

It’s a favorite spot for couples, people looking to get high and meditate on life, and teenagers too cool for school.

It endures as a warning to would-be developers who prioritize quick profits over long-term community.

On the inside of the barrier wall that people jump to enter Sunken City—between communities still intact and the desolation of a neighborhood that slid into the sea—a graffiti artist created a chubby blue water drop with mournful eyes.

As if warning us.

There are humans sounding warnings also.

“The cliffs have more time and more natural impetus to move,” DiFiori said.

She stands by beneath a sign at Bluff Cove that warns of falling rocks “They’re not going to care how much money you spend to preserve structures,” she added.

Mother nature has a bigger budget.”

situated right next to the Point Fermin Lighthouse park.

However, it is also home to one of the most infamous geological disasters of the early twentieth century.

Sunken City is a beachfront area that was abandoned after a slow-moving landslide in 1929.

Over the following decades, pieces of the coastline would slip into the ocean.

At one point, geologists measured the sinking of the coastline at an average of 11 inches per day.

The area was eventually fenced off and signs posted warning of fines after

complaints from the neighboring residents poured in about the loud music and roaring bonfires that occurred in the area.

That did not stop the art and artists from flowing into the landscape looking for an open canvas to create various pieces of art.

As AJ finally finds a place to make his canvas, he pulls out his cans and his friend sparks the tail end of a blunt.

“People come here for all the right reasons,” AJ said. “It’s a diverse place for people of all backgrounds to come together.” @itsecohen

Above left — Point Fermin community in the 1920s just before the landslide, or “slump,” began in 1929. The area that fell into the sea, now known as the Sunken City, is directly above the the Point Fermin lighthouse and park. The street and homes that fell are visible on the right along the edge of the cliff. The same street is above right after the landslide and below today.
