Sadly it seems that for the younger generation writing most articles on the Internet today if they didn't see it in their lifetimes then it never happened. This ranges from moon hoax nutters all the way down to believing whatever they just learned about never happened before whatever event caused them to learn about it.

In spite of popular misconceptions caused by a lifetime of poorly conceived "creature features" from the 1950s onwards, radioactivity in the oceans is relatively harmless compared to the chemical pollutions that are of huge concern.

"Properly treated sewage" effluents from municipal plants are responsible for discharging wastes where the bacteria count has been altered and much reduced. However the treated wastes contain the entire modern pharmacology of everything humans consume, from human growth hormones to elaborate organic chemicals to oddball vitamin supplements from everywhere on Earth. Agricultural runoffs contain a huge abundance of fertilizers and pesticides and herbicides, as does human wastes from food crops grown with such chemicals.

Most of it causes widespread algae blooms, and huge unbalances in plankton growth. Eventually, these chemicals end up in the flesh of the "filter feeders", the fresh and salt water shellfish, which in turn are a major human food source the world over.

Places like China and other Eastern countries have long used human wastes as fertilizers to grow rice. The recycling of chemicals is even shorter there, and humans who have never received or consumed antibiotics for example have measurable levels of common antibiotics and when they develope infections, these are antibiotic resistent strains. Here in the Western World we are beginning to practice "sustainable agriculture" in many forms, including typically a compost pile that serves up a witches brew of everthing that was ever used on the soils being fortified with organic composts.

It's just one more symptom of an overcrowded planet. I actually think that most people get obsessed with radioactivity for two reasons. The first being the afore-mentioned "creature features", popular since the end of WW2 and the bombing of Japan (which of course afflicted that country with Godzilla). The second is to avoid thinking about the huge range of persistent organic and inorganic chemicals that now circle the planet in an unavoidable, all pervasive shroud of death. It is the message from Silent Spring, writ large and incrementally worse as the years pass by and we add more and more chemicals to our bodies.

Upthread, T mentioned using seaweed for cattle fodder. Apparently, there are some other benefits to this idea:

I can't take credit for the idea. Years ago I read an article about abandoned feral cattle on an island somewhere in the Pacific. The government scientists who eventually studied the place were astounded so many cattle lived on an island with limited grazing land until they figured out that the abundant seaweed that washed ashore every day made up a large percentage of their total diet.

If I could remember the name of the island I would post it, but this was at least a decade ago and my memory isn't as solid as it used to be.

I don’t think saragosum counts as seaweed, it’s an alge apparently.

All seaweed, including the kelp used to wrap sushi, are species of Algae.

Brittanica wrote:Seaweed, any of the red, green, or brown marine algae that grow along seashores. Seaweeds are generally anchored to the sea bottom or other solid structures by rootlike “holdfasts,” which perform the sole function of attachment and do not extract nutrients as do the roots of higher plants. A number of seaweed species are edible, and many are also of commercial importance to humans. Some are used as fertilizers or as sources of polysaccharides.

OK.

But does that mean saragosum is edible? Or even edible by cows? On Montserrat they brought in professional hunters to reduce wild cows. Didn’t see a lot of cows elsewhere, ones and twos. But also it’s not like there is a lot of beach, there are a LOT of cliffs and very steep land at waters edge.

I’ve tried to eat some seaweed they collect in Nova Scotia, nasty.

The only positive I saw of it was maybe stopping some beach erosion.

Someone in Texas of Mexico has been using Sargasso to supplement sheep feed, given what I know about their digestion if they can eat it cattle should be able to do the same.

I agree with you on this, and I was slightly encouraged because of the work done on substituting chemicals with a shorter half-life for those which are capable of doing so much harm.
Some places, however, still require extensive fire retardation in household furnishings (example: California still requires a 12 second flame exposure which is still accomplished by brominated flame retardants, which are known to cause retardation in infants.
Maybe this is another case of letting a government agency legislate engineering.

Declining oxygen in the global ocean and coastal waters

...Rising nutrient loads coupled with climate change—each resulting from human activities—are changing ocean biogeochemistry and increasing oxygen consumption. This results in destabilization of sediments and fundamental shifts in the availability of key nutrients... these conditions are unsustainable and may result in ecosystem collapses, which ultimately will cause societal and economic harm.

Off topic but some interesting photos. Worth a look.
