12 year acct here. Uhhh. Yeah, probably. But there's also millions more users than ever before, and alot of people have alot of reasons to be unhappy. So it's not surprising alot of comments come of extra doomy lately if a large portion of the population is apprehensive af about the future. Having your worries come through casually in a .5 second comment you've thrown into the wind without even necessarily expecting to be replied to, or even intending to read any replies is pretty whatever behaviour, my dude. Is it unhealthy? To ocean conservation efforts, certainly, but maybe it's like a 2020's stress ball for the type of rando's who rightly believe alot what the UN does is lip service, or worse, what the musicians on the titanic did (or didn't do, I admit I'm pulling from the movie here)

The point is if there's more people you see on reddit that feel like doomers, maybe that's simply because there's more people lol. Welcome to the information age, where we get to share all the shitty things 24/7 more or less unrestricted to anyone else in the world at a moments notice
