Due to the acidification of the ocean, there's an overpopulation of squid in the seas. It would actually be beneficial if people started eating more of them, because they're predators of other fish species that we ourselves are already overfishing. Note: I'm not an environmentalist, it is just something I noticed.
In fact, I have a modest proposal to share with you on that front.
I'm Korean so dried squid is my favorite snack but it costs $50 for 10 of them in NYC. Would not recommend this snack though, I hear it's pretty harsh on your teeth.
I haven't seen as much evidence for squid intelligence as for octopuses.
