CNN adopted a world workforce of whale specialists during 2023, from Friedlaender’s lab on the University of California at Santa Cruz to humpback breeding grounds off the Pacific coast of Colombia, трип скан and their feeding grounds at the bottom of the planet.
Using a playlist curated by astronomer Carl Sagan and impressed by the way humpbacks use reduced frequencies to deliver messages across whole oceans, they had been launched on NASA’s two Voyager probes in 1977.

“And that’s what feeds the food for whales, birds, seals — anything. They’re fundamentally farmers recycling nutrients and there’s more foodstuff available to them the greater they’re around.”
But Just about a fifty percent-century afterwards, the comeback from the humpback is arguably the best good results Tale inside the record of conservation.
