It’s not just toxic chemicals. Radioactive waste was also dumped off Los Angeles coast – the Los Angeles Times

For decades, a graveyard of corroding barrels has littered the seafloor just off the coast of Los Angeles. It was out of sight, out of mind — a not-so-secret secret that haunted the marine environment until a team of researchers came across them with an advanced underwater camera…Startling amounts of DDT near the barrels pointed to a little-known history of toxic pollution…but federal regulators recently determined that the manufacturer had not bothered with barrels. (Its acid waste was poured straight into the ocean instead.)…

Along California’s 1,200-mile coastline, the overheated Pacific Ocean is rising and pressing in, imperiling both wildlife and the maritime towns and cities that 27 million people call home. In California Against the Sea, Los Angeles Times coastal reporter Rosanna Xia asks: As climate chaos threatens the places we love so fiercely, will we finally grasp our collective capacity for change?
How does sea level rise challenge modern notions of property lines? – Los Angeles Times

The (California) Coastal Act is a remarkable commitment to the public trust doctrine, which traces back to Justinian I, who declared in 533 C.E. that “the following things are natural law common to all: the air, running water, the sea, and consequently the seashore.” This notion — that certain lands should be held in trust by the government for the benefit of all people — evolved into English common law, which the United States then adopted and California later wrote into its state constitution…
