My bad; I misunderstood your comment.
I was operating under the assumption that people would read the article and not think that at all, but you're absolutely right: the type of people who would say we should just keep churning out plastic are probably not the ones taking the time to actually look at articles.
That's actually the opposite of what the article is about! It's about reducing plastic production by creating biodegradable packaging using seaweed.
So, nothing to do with seaweed eating plastic, though I get why you would assume that. Seems every other week there's an article about a fungus or bacteria or magical plastic fairy that will make plastic disappear.
I hope the fact that this is a front-end solution to try and stop churning out plastic brightens your day. Wishing you a lovely weekend!
