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."

Water is emerging as the critical constraint shaping sustainable construction and urban development. A United Nations warning of “water bankruptcy” positions scarcity as a core determinant of sustainable building design, forcing developers to integrate hydrological data into every feasibility study. Growth strategies in arid regions are now being rebuilt around circular economy in construction principles—combining closed-loop water systems, onsite reuse, and lifecycle assessment to ensure resilience in resource-constrained environments. The shift highlights the rise of life cycle thinking in construction, where water efficiency aligns with carbon footprint reduction and long-term life cycle cost outcomes.
Reconstruction in disaster-prone areas is demanding a redefinition of sustainable building practices. Indian townships rebuilding after landslides demonstrate the limits of traditional resilience models. A data-driven approach grounded in environmental sustainability in construction is replacing reactive rebuilding with preventative planning. Projects now value green infrastructure and community-led hazard mitigation as core performance indicators, embedding end-of-life reuse in construction and low-impact construction techniques as benchmarks for sustainable design.
The fragmented global energy transition continues to disrupt the carbon footprint of construction. As the embodied carbon of steel, cement and modular components depends heavily on place of manufacture, procurement teams are pursuing environmental product declarations (EPDs) and low embodied carbon materials to manage embodied carbon in materials more transparently. Contracts increasingly price carbon volatility alongside inflation and currency risk. Design professionals are under growing pressure to evidence net zero whole life carbon performance through rigorous whole life carbon assessment and life cycle cost modelling. This progression marks the industry’s deeper commitment to decarbonising the built environment and achieving carbon neutral construction.
Corporate investment is translating ambition into deliverable outcomes. Housing and workplace projects benchmarked against BREEAM V7 and net zero carbon buildings standards are demonstrating measurable improvements in green construction efficiency, renewable building materials integration and circular construction strategies. The distinction between retrofit and replacement is being framed by whole life carbon considerations and building lifecycle performance metrics. Each project is an applied case study in sustainable material specification and eco-design for buildings, proving that low carbon design and resource efficiency in construction are now commercially viable rather than aspirational.
Sustainable construction is no longer an environmental choice but an operational necessity. The convergence of water scarcity, embodied carbon accountability and resilience-based planning ensures that sustainable building design now serves as the foundation for both climate adaptation and long-term asset value.
