Yeah, I only bring up oceans because OP specifically mentions them as the reason plastic production is bad in their letter.

Re. plastic foam, it's interesting: because it's so light, I'm guessing relatively little material is used in manufacturing what feels like so much wasted stuff. It's difficult for me at least to trust my intuitions about what policies are good for the environment: see the recent study showing that disposable K-cups use less energy than making coffee from scratch.

For sure. This is very much the "electric car" problem. Electric cars are terrible for the environment, but electric cars are still a good thing because we need to push for renewable energies. It's more about framing and making sure you know what issue you are addressing. In this case, it's about reducing plastic waste, especially microplastics in our water and plastic in the ocean. While paper bags don't necessarily help the forests, they do reduce microplastics

While I 100% support all waste-reduction incentives, what's interesting is that our instincts may actually often be backwards when it comes to plastics.

Take single-use plastic bags. If you have an organic cotton bag, it would need to be re-used hundreds of times to have the same carbon impact as a single-use plastic bag, and thousands of times to have the same water impact as that plastic bag. (Source 1, Source 2)

If, like me, you have 5-10 reusable bags, you need to use them tens of thousands of times to offset the emissions and water impacts they had, compared with if you had used single-use plastic bags the whole time.

And paper bags, from that source, would have to be reused 40 times, which is unlikely ever to happen.

(Note, my take-away from that study is not to not use my reusable bags, but to make sure I use them as many times as possibly possible. But also, if I forget my bag, I should use single-use plastic rather than paper (bad) or buying yet another bag (much worse).)

Our instincts usually come from a "visible trash" perspective, we assume that what we see littering is the worse thing. But actually from a climate change and water freshness perspective, this is not always correct. (And, interestingly, studies have shown that all plastic bags make up less than 1% of litter.)

I'm not sure the point I'm trying to make: initiatives to stop trash and waste are definitely good. But that our good intentions aren't always correct when it comes to plastics, so we should try to look at the available research, and let that guide our decisions, more than our gut instincts.

Mostly developing countries, China, and India.

But that's only for the oceans. The US puts its plastic waste in landfills instead. And yes, large-scale uses like shipping material is far more than what you use as an individual. Any time I get a pallet of something at work, I have to throw out so much plastic foam. At least we're the end consumer and not repacking it with new material to be shipped out again.

But what is congress supposed to do about the Philippines? There is no reason we should say "those guys are worse so we don't need to do anything". Microplastics are everywhere, and companies like Amazon generates billions of tons of plastic every year, most of it single use. It's certainly going to help the planet much more to hold Amazon accountable than for you to stop using a plastic straw
