How is it that this is waterproof and durable packaging material, but also easy to decompose at home? It seems to me on the surface that those two things are at odds with each other.

That was my question exactly. A big reason why plastics are useful are because they are so difficult to biodegrade, and can thus form a water, air and germ proof barrier.

They can actually choose whether they want to be milked every morning. One line leads to a tiny milking station. There, retired surgeons use designer nanopumps to relieve silk gland tensions.

It seems rude to trivialize efforts that reduce the unnecessary suffering and killing of billions of animals every year, don’t you think? The last paragraph is ripe with ignorance, too. What exactly were you trying to achieve with your comment?

Seems to be a pattern with human thinking. Plenty of noble causes, some recent and very very public, get tarnished because of select bad actors. I don't know why but so many of us seem to look for reasons to say that X isn't a problem.

Whether or not i agree with (loud) vegans shouldn't affect the idea that our treatment of animals in large scale slaughter is abysmal. By nearly any measuring stick.

Why are we so prone to write off large, obvious movements? I see it so frequently.. yet i look for a reason to not hate the people that write-off, because it feels like so, so many.

Here in the NL, plastic bags are an extra charge (at least where I shop), it costs just a tiny bit extra to get nice reusable ones or bring your own - you can return most other single use plastics — like bottled water — and get your money back. This alleviates #1 above, but I don’t think it would ever fly in the US. Here, grocery shopping is almost a daily experience in the city. You can’t walk 10 minutes without pas…

The problem with bags is - let's call it the bachelor shopper. A modern man's clothes may have pockets, but he rarely wears any kind of handbag in which to hold the reusable shopping bag. So it doesn't matter if they cost 1c, 10c or 1 eur - I am always buying new bags, have nowhere to put the bag when I am going outside. At least I also use them to throw away trash.

Since NY doesn't have plastic bags for most shopping anymore, you see a lot more men carrying bags for shopping.

Fwiw, I throw a canvas bag in my pocket when I'm going to shop somewhere. And a lot of people carry backpacks anyway.

> It has been at least a decade since the futility of plastic recycling has been known. To you. Not to the general population.

I do not think it would make a difference. Replace plastic recycling with the harms of carbon emissions, surely that has been known by sufficiently many people. When push comes to shove, sacrifices on a collective basis are hard to make. Especially when you can point to others that are not making them.

>Especially when you can point to others that are not making them.

Each country is only responsible for x% of global emissions. The rest of the world is responsible for 100%-x%. As 100%-x% > 50% each country has to do nothing as the rest of the world is always the worse polluter.

What is this type of fallacy called? I see it all the time.

It was meant in jest, but if you must take it seriously, my opinion is that veganism as a movement has largely been coopted by high-gloss, low-impact "plant based foods" marketing that follows all the aesthetics and few of the values of older movement. There isn't a measurable decrease in meat production or consumption, just a noted increase in overpriced prepackaged vegan food products.

I say that as a vegan of more than a decade. Its recent popularity is more indicative of successful marketing than consciousness raising. It's just another fad diet to folks, not a lifestyle change resulting in better livestock conditions.

Because single use plastics are transformatively essentially for the entire modern way of life? Until we acknowledge that reality any solution will only sound hypocritical and be ineffective in the end. The only real solution I see for plastic waste is just to incinerate it and try to build carbon capture plants to undo that fire.

What's to acknowledge? Paper bags work just as well, much of the products absolutely don't need that much plastic packaging, and people lived fine with reused glass bottles/jars (at least some countries still recycle that).

For those interested Ted-Ed did a neat video on the topic of grocery bags.

Looking at a full lifetime you need to reuse cloth bags thousands of times to break even on their higher impact. For sturdier plastic reusable bags you need to reuse them a few hundred times to break even.

Could you explain what you mean? I find it hard to believe that the environmental impact of one sturdier plastic bag is equivalent to hundreds of slightly flimsier bags. I’ve shopped in a few European countries, and found the reusable plastic bags have maybe twice or three times the mass of the “non-reusable” one. I can’t see how they would have multiple orders of magnitude environment impact.

I have not yet verified the references, but this SciShow episode seems to propose exactly that: https://youtu.be/JvzvM9tf5s0

The unnecessary inclusion of 'spider' in the article makes the claim 'vegan' suspect. It's plant-based silk. There are many creatures that spin silk, no need to mention "spider-like" specifically.

I agree it's confusing in the title, but in context in the article it's more clear that the researchers call it "vegan spider silk" to capture their intention of creating a material with the properties of spider silk, using the same structure that makes spider silk strong at a molecular level, but using raw materials that can be sustainably derived from plants.

I took it in jest. I just thought the spiders were eating what they normally do, but consenting to give us milk somehow, despite the fact they don't have nipples.
