How to make sustainable seafood choices this Christmas to ease the pressure on Australia’s oceans
"Last year the market traded about 350 tonnes of seafood over the Christmas period, with 120t of prawns and 70,000 dozen oysters among the top sellers...Australian Marine Conservation Society’s GoodFish guide aims to showcase the most environmentally friendly seafood sources."

https://www.theguardian.com/environment/2025/nov/22/how-to-make-sustainable-seafood-choices-this-christmas-to-ease-the-pressure-on-australias-oceans'Sustainable Fishing' is a Lie
"Fishing sustainability is based on a pseudoscientific theory that justifies taking the most marine life for maximum profit. Sustainable fishing is a deception, a myth motivated by the ideology that life on Earth belongs to humankind."

Global oxygen decline in the ocean
Ocean hypoxia: The science of climate change in the sea"... The field will need to draw on ... advances to meet demands for adaptation solutions to the continued progression of global ocean deoxygenation, particularly in conjunction with ocean acidification and marine heatwaves in a multi-stressor scenario."

So, something else that is a key element of ensuring #HumanWelfare remains in the SW range is to make sure folks are fed -- without destroying the environment! That's where #RegenerativeAgriculture , #SustainableAgriculture, #FoodForests, #CommunityGardens, etc., come into play. But #Rewilding and restoring key natural systems are also very important!
7. #Wildlife faces #extinction cascades as #ecosystems collapse.
"Vertebrate populations have declined by an average of 69 percent since 1970, with some regions experiencing losses exceeding 90 percent as habitat destruction, climate change, #pollution, and direct #exploitation combine to trigger ecosystem-wide collapse that eliminates the #biodiversity necessary to maintain stable #FoodWebs. Species extinction rates now exceed background levels by 100 to 1,000 times, representing a mass extinction event comparable to the asteroid impact that eliminated the dinosaurs but compressed into a timeframe measured in decades rather than millennia.
"The collapse of insect populations threatens #pollination services essential for agricultural production, while marine ecosystems face #acidification, warming, and #overfishing that eliminate entire trophic levels and destabilize ocean food chains supporting billions of people. Domestic animals face parallel threats as #IndustrialAgriculture concentrates genetic diversity into vulnerable #monocultures while climate change disrupts feed production and increases disease pressure on livestock populations already stressed by intensive production methods designed to maximize short-term yields rather than long-term #resilience."

#NPR: The U.S. takes a step toward allowing #mining on the ocean floor, a fragile #ecosystem
by Julia Simon, April 25, 2025
"President #Trump signed an executive order Thursday aimed at making it easier for companies to mine the deep seafloor, saying it would create 'a robust domestic supply for critical minerals.'
"There is currently no commercial-scale deep-sea mining anywhere in the world. But companies have long eyed the ocean floor as a potential source of metals like nickel, cobalt, manganese and copper, which are used in batteries for electric vehicles and other technologies.
"The world has no rulebook for deep-sea mining. One company is pushing forward anyway
"These metals can be found in potato-sized nodules lying on the ocean floor. Many of the nodules are in the middle of the Pacific ocean, beyond the legal territory of individual countries.
"Thursday's order might circumvent ongoing international negotiations to regulate deep-sea mining.
"Those regions have traditionally been overseen by an international organization, the #InternationalSeabedAuthority (#ISA). The ISA has hosted talks for years to try to hammer out a rulebook to govern a potential seabed mining industry. The U.S. did not ratify the treaty that governs the seabed, and is not a voting member of the ISA, though in the past under previous administrations it has respected the ISA process.
"In his executive order, Trump instructed federal agencies to expedite the process for reviewing and issuing permits for mining on the seafloor in both U.S. and international territory. It will use a U.S. law from 1980, the "#DeepSeabed Hard Mineral Resources Act."
"Scientists and environmental groups condemned the order, arguing that opening the deep seabed for mining could disrupt important marine ecosystems, and damage the fishing industry.
" 'This is being planned on some of the least resilient #ecosystems on the planet,' says Douglas McCauley, professor of ocean science at the University of California Santa Barbara. 'It would have #catastrophic biological consequences.'
"Underwater mining can create plumes of sediment that could suffocate marine life, and degrade the #FoodWebs that fish depend on, McCauley says.
"There are also important questions about whether we actually need to be mining the seabed to get enough of these minerals for technologies like batteries, says Micah Ziegler, assistant professor of energy and chemical systems at Georgia Institute of Technology.
"While a couple of years ago researchers were concerned about the limitations of land-based mining for metals like cobalt and nickel, a variety of alternative #battery chemistries have been developed that might reduce the need for those elements, Ziegler says."

#Ocean #heat is changing #marine #foodwebs – with far-reaching consequences for NZ #fisheries and #sea life
Warming is already threatening #coralreefs – #GreatBarrierReef is hottest it’s been in 400 years – and marine life. But it is also reshaping #ecosystems at the very basis of #ocean food webs. Scientists are observing a downward trend in #phytoplankton leading to expanding “ocean deserts” and the depletion of beneficial microalgae in favour of harmful algal blooms.

Models may gain to consider multiple diversity facets and their corresponding sources of trait adaptation. Read more at https://doi.org/10.1111/oik.10544.

What the #Dragonfly Knows https://nautil.us/what-the-dragonfly-knows-331829/
"They crisscross the globe in search of breeding and foraging grounds, and some species can travel at up to 30 miles an hour. In the process, #dragonflies connect distant #ecosystems and #FoodWebs—like other migrating #insects.
#Researchers have begun trying to trace their #MigratoryRoutes to better understand the impact they have on food cycles, the distribution of nutrients, #pollination, and the spread of disease-causing #microorganisms."

#Summer is here. Where are the #fireflies? In so many spots where scientists look, #insects of all sorts are #vanishing, w potentially disastrous results. Populations are plunging in Germany, the Netherlands, in Puerto Rico and American West, leading to fears of a potential-though-still hotly debated #bugpocalypse which could unravel #foodwebs for #birds & other #insecteating #animals and cause calamity for #farmers who need #pollinators to grow crops. #NoMoreButterflies https://www.washingtonpost.com/climate-environment/interactive/2023/firefly-summer-extinction/?itid=hp-more-top-stories_p003_f003

A gradual #decline in #biodiversity may have led to a more devastating #ecosystem #collapse during the #PermianTriassic #MassExtinction , according to #NewResearch .
#Scientists #recreated #ancient #FoodWebs to determine how #species were #impacted during this event. But how well can our knowledge of past #extinction events #inform us about the #CurrentCrisis of #SpeciesLoss ?

The 'brown #FoodWeb': Dead vegetation found to play essential role in #desert ecosystems https://phys.org/news/2023-01-brown-food-web-dead-vegetation.html
#Herbivores’ Impacts Cascade Through the Brown Food Web in a #Dryland https://link.springer.com/article/10.1007/s10021-022-00810-4
Overgrazing can disrupt the desert #FoodWebs that exist between dead plant material, #termites and #animals that rely on termites as their main food source.

Jet-Propelled #Tunicates Pump #Carbon Through the Oceans https://eos.org/research-spotlights/jet-propelled-tunicates-pump-carbon-through-the-oceans
Populations of these gelatinous #zooplankton are episodic, patchy. Sometimes they bloom and form huge aggregations. Their feces, daily migrations, and sinking carcasses sequester carbon into the #DeepSea. This is especially prominent in retentive or low-export #FoodWebs.
