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."

A tightening regulatory and technical landscape is redefining sustainable construction across the UK and beyond. The Building Safety Act is reshaping project governance by requiring transparent reporting and accountability that link safety with environmental sustainability in construction. Compliance processes are driving a shift toward whole life carbon assessment, embedding sustainable building design principles at the earliest design stage and quantifying both operational and embodied carbon.
Digital systems such as the government’s waste‑tracking initiative are enabling circular economy in construction practices, mandating traceable material flows and revealing the carbon footprint of construction through verified lifecycle assessment. These data‑driven mechanisms enhance resource efficiency in construction and reinforce the wider transition to low embodied carbon materials and eco‑friendly construction.
Investment is converging on decarbonisation at scale. A new £120 million waste‑to‑hydrogen facility is designed to transform residual waste into clean fuel, supporting low carbon design and resilient net zero carbon buildings. Growth in grid‑balancing storage improves the stability of renewable‑powered operations, a prerequisite for energy‑efficient buildings and low carbon building performance across portfolios.
Governance frameworks are also advancing. The creation of a dedicated leadership structure for the Greenhouse Gas Protocol elevates global consistency in measuring whole life carbon and encourages transparent benchmarking using environmental product declarations (EPDs). This maturity strengthens sustainable building practices, fosters green construction aligned with BREEAM v7 standards, and supports decarbonising the built environment through life cycle cost and performance management.
The cumulative effect signals a transition to net zero whole life carbon imperatives governed by robust data, certified materials, and measurable outcomes. The progress may appear administrative, yet it represents the essential infrastructure of sustainable material specification, circular construction strategies, and long‑term green infrastructure supporting a truly carbon neutral construction sector.
