Garbage-patch tale as flimsy as a single-use plastic bag – SFGate

Garbage-patch tale as flimsy as a single-use plastic bag – SFGate:


So the GREAT Pacific Garbage Patch is not real… Or maybe not nearly as big as originally expected.


Saunders does a great job of attaching the myth behind the original reports of “the size of Texas” and such.


Great sources of info included.


But now I’m really worried. The amount of plastic floating in the oceans amount to only (right, only) 7,000 to 35,000 Tons. But we know the amount of plastic produced each year, the % that gets recycle, the % that goes into a landfill and the paltry % that gets repurposed. That leaves a LOT of tons of plastic each year that go into the environment. If we estimate the amount that goes out the water systems into the oceans you get a LOT of plastics into the oceans. There’s a lot of large pieces but the small stuff is mysteriously missing.


There’s bit of a mystery working that is well discussed here at the SFGate with four possible theories by Leslie Baehr. None of them look good. The plastic found represent only about 1% of the plastic pollution in the ocean according to one of the researchers Cózar said. More could be hiding below the surface. 

“Indeed, the quantity of plastic floating in the ocean and its final destination are still unknown,” the researchers concluded.
It may take hundreds or thousands of years for plastic to degrade. In the warm ocean with lots of sunlight, maybe only 1 year. See here on degrading and the short artgument as to whether plastics ever really biodegrade (although the degrade to smaller bits of the same).  Here’s a nice little biodegadable table by the NH for the National Park Service, talking about 20 years for plastic bags and 450 for plastic bottles to biodegrade.

All that plastic is going somewhere. I was actually happier knowing where it was going… into the Great Pacific Garbage Patch. Now we don’t know, what we don’t know. That’s worrisome!

    A Tale of Two Reports: Why the DOE’s Climate Assessment Demands a Reality Check

    ByPiAdmin

    A Working Group (of 5) Came out with a “Moderate” Report for the DOE A new DOE climate report has been released by the U.S. Department of Energy at the end of July 2025. Authored by five “independent” researchers, it concludes that the economic damages of climate change may be less than believed and that aggressive action could be more harmful than the problem itself. Essentially, the report says that often doing nothing is better…

    Finding Where U.S. Forests Have Been Undisturbed for a Quarter Century « Landsat Science: This is a very cool study of the “old forests” that are undisturbed in the USA. The Northeast and the pacific maintained some undisturbed forests; the south was really bad. There are many plants, animals and entire ecosystems that rely on old forests. This study demonstrates how bad it is and how much worse it could get over the next few…

    Unsustainability as the Engine of Sustainability and Scenario Planning

    ByPiAdmin

    Sustainability and scenario planning Synergy. Sustainability and scenario planning may seem like two separate domains—one focused on resource stewardship and long-term resilience, the other on mapping uncertainties and preparing for multiple futures. Yet they are deeply intertwined. Anything that is not sustainable will eventually fail, and in that failure lies the seed of future scenarios. By integrating sustainability thinking with foresight methods, leaders can anticipate not only the risks of collapse but also the opportunities…

    California Becomes First State to Mandate Solar on New Homes – Bloomberg: California is 1/3 of the US economy and probably 1/3 of the US housing market. So, when California voted today to have mandatory solar on most new construction houses, this blows the top off of the non-solar rooftop. Headlines read that the CA house will now cost about an additional $10,000 to build with the energy efficiency and solar roof mandates. This Bloomberg…

    Monarch & The Milk Weed … to plant, or not to plant?

    BySustainMe

    Monarch Deformities — A Growing Concern There is a pesty parasite that is killing the monarchs in all stages of their life cycle. The parasite is called OE for short. It appears that with a warming climate, the monarchs don’t migrate and the non-native milkweed doesn’t die back in the winter, especially in Florida. This seems to perpetuate the life cycle of OE and negatively impact the monarchs.  Recent field observations have shown monarchs emerging…
