Along some 70 miles of Southern California coastline, usually curious and playful sea lions are attacking humans in the water.
The animals are being poisoned by the ocean they live in, experts say, citing reports of sick sea lions at unprecedented levels. And many are dying.
Pheobe Beltran, a 15-year-old girl in Long Beach, was swimming on March 30, when a sea lion attacked her right arm.
"I was just so scared, so shocked, but I still felt the immense pain on my arms, like, over and over again," Beltran, who was finishing up a 1,000-yard swim during tryouts to become a junior lifeguard, told CNN affiliate KCAL.
Up the coast in Ventura County on March 21, a surfer near Oxnard, was bitten by a sea lion in open water. The attack left him "shaken" to his core, he said.
The cause is less demonic and more likely domoic acid toxicosis caused by toxic algal bloom, often referred to as red tide, experts say.
"The sea lions are coming in almost comatose by the time they're stranding. Something is happening in this particular bloom that seems worse on multiple levels," John Warner, CEO of the Marine Mammal Care Center in Los Angeles, told CNN.
"But volume-wise, it's definitely the worst we've ever seen."

Compressed earth block projects in Kenya’s drylands are signalling a shift towards sustainable construction that balances material performance with environmental sustainability in construction. By replacing kiln‑fired bricks and cement with locally produced low embodied carbon materials, these buildings achieve reduced embodied carbon while enhancing thermal comfort through passive design. The combination of thermal mass and vapour‑open walls supports sustainable building design adapted to warmer climates and delivers measurable gains in lifecycle assessment and life cycle cost efficiency.
As whole life carbon and embodied carbon in materials become central to regulation and procurement, codification and quality assurance will dictate how rapidly such natural materials scale to mainstream use. Compressed earth blocks in Kenya exemplify how local innovation aligns with sustainability targets and social benefits for communities adapting to climate stress.
European policy is steering the supply chain towards a circular economy in construction. Tighter controls on plastic imports are designed to foster a stable market for compliant recycled polymers and strengthen traceability. For manufacturers pursuing higher recycled content, this supports circular construction strategies and improves environmental product declarations (EPDs). For specifiers and project teams, it provides a stronger evidence base for whole life carbon assessment within sustainable building practices and reinforces the commitment to resource efficiency in construction.
The UK’s accelerating offshore wind capacity, now exceeding 16GW, deepens the transition towards net zero carbon buildings and reduces the carbon footprint of construction by decarbonising energy supply. As sites electrify and equipment integrates renewable sources, the alignment between energy‑efficient buildings and carbon neutral construction grows closer. This shift enables data‑driven evaluation of whole life carbon performance and encourages contracting models that value carbon intensity alongside cost, advancing low carbon design and net zero objectives across the sector.
In alpine zones and high‑risk regions, the integration of climate‑informed planning, geotechnical monitoring and enforceable safety zones underscores the need to view climate adaptation as a core aspect of sustainable architecture. Infrastructure such as Spain’s high‑speed rail demonstrates how green construction combined with whole life carbon accounting can deliver deep emissions cuts while improving resilience. The global construction industry must merge such systemic decarbonisation with eco‑design for buildings, green building materials and sustainable material specification, ensuring that every project contributes to long‑term building lifecycle performance and to decarbonising the built environment.
