Global nutrient transport in a world of giants | PNAS
Animals play an important role in the transport of nutrients, but this role has diminished because many of the largest animals have gone extinct or experienced massive population declines. Here, we quantify the movement of nutrients by animals in the land, sea, rivers, and air both now and prior to their widespread reductions. The capacity to move nutrients away from hotspots decreased to 6% of past values across land and ocean. The vertical movement of phosphorus (P) by marine mammals was reduced by 77% and movement of P from sea to land by seabirds and anadromous fish was reduced by 96%, effectively

Studying Humpback Whales to Better Communicate with Aliens
"In this video, a pair of scientists talk about their work in studying the communication patterns of humpback whales to learn more about how we might someday communicate with a possible extraterrestrial intelligence. No, this isn’t Star Trek IV. For one thing, whales have tailored their communication style to long distances, when it may take hours to received a reply, an analog of the length of possible interplanetary & interstellar communications. The scientists are also using Claude Shannon’s information theory to study the complexity of the whales’ language and eventually hope to use their findings to better detect the level of intelligence in alien messages and perhaps even the social structure of the alien civilization itself."

P.S. Fascinating whale facts are sprinkled throughout the video. Humpback whales “have had the Ocean Internet for millions of years” and can communicate directly with each other up to 1000 km away. That means that a whale off the coast of Portland, OR can chat with another whale near San Francisco.

Dead Sperm Whale Washes Up With 150 Plastic Cups in Its Stomach
The waters along Southeast Asia suffer from an inordinate amount of plastic pollution as the world’s top plastic polluters are concentrated in this area: China, Indonesia, the Phillippines, and Vietnam. Between 55 to 60 percent of the plastics that enter our oceans come from this rapidly developing region, according to a 2017 report from Ocean Conservancy.
