  1. A study off the California coast has uncovered a sharp decline in blue whale songs during marine heatwaves—an effect linked to collapsing krill populations and rising ocean stress.

    With less food and disrupted foraging patterns, the whales spent more time searching for prey and less time calling. In some years, vocalizations dropped by nearly 40 percent. Similar patterns have been recorded in New Zealand, suggesting a broader climate-driven shift across the Pacific: [https://on.natgeo.com/BRRD20250730](https://on.natgeo.com/BRRD20250730)

  2. Such a terrible evil being committed by some human beings, a heinous crime against nature

  6. Face its just a matter of time before oceans die, then we will too

  7. But all these climate deniers keep telling lies to everyone and they are now pushing back pollution controls.  Everyone needs to speak up and make your voice heard before it’s too late for all living things on this planet!  The US is a huge culprit and now going to be worse to help corporate greed at the cost of all of us.
