Re: Plastic in Pacific Ocean Gyre

If you've bought sturdy, reusable bags from your supermarket, it's likely they're made from non-woven polypropylene - and they are less damaging, but only if you use them at least 52 times.
That's according to a report* by the Danish government, which weighed up the varied environmental impacts of producing and disposing of different kinds of bag.
And if your reusable bag is organic cotton, don't feel smug - the researchers reckon they need 20,000 uses to justify themselves. That's a shopping trip every day for over half a century.

This is an interesting article, and it does highlight that just banning the plastic grocery bags is not just a straightforward solution. As with most things its more complicated and requires more than just one thing to make things "Better".

It also really makes you stop and think before just changing your habits before you really understand the issues.

With all the talk of this giant island of plastic, I have never once seen a picture of it.

With the amount of utterly ridiculous pictures I do see.....................

Speak for yourself. My household produces less than five gallons of garbage a week, with a majority of that recycled in my red worm compost pile, including junk mail.

My energy bill reports that I am 45% more efficient than the modern so called high efficiency homes.

Guess that proves that most of this big 'my new stuff is more efficient than your well maintained old stuff' is BS.

There oughta be a LAW!!!!

Re: Plastic in Pacific Ocean Gyre

We try to reduce the number of single use plastic bags in my household. We have the re-useable ones that I use almost every single time I go to a store. I sometimes leave them at home as I need to restock my supply to pick up after my dog when we go on walks.

Recently CA had an outbreak of Hepatitis which they could trace back to the lack of sanitation for the homeless. The homeless used to use a plastic bag in many cases from the grocery store instead of it being left on the ground or street. The lack of access to plastic bags helped to increase and speed at which the disease spread. One of the unintended consequences of the plastic bag bans.

Published today. Its limited to macro plastics, although there’s 60 years worth of plankton samples to look through for microplastics if anyone’s interested?


And of coarse worms will break it down to make it more bioavailability....

That URL did not work for me. But this one - to the open publication of Ostle et al., The rise in ocean plastics evidenced from a 60-year time series, should work:

https://www.nature.com/articles/s41467-019-09506-1

Only the Atlantic Ocean, mind.

Re: Plastic in Pacific Ocean Gyre

I wonder why they don't build boats out of plastic bags? Sounds to me, like they are the one thing the ocean can't destroy. 500 years? I'll take one.
