So that climate change in mass media thread made me bring up a thought I haven't had in a while (and tbh I didn't want to bring it up in that thread cause it would veer off topic if I did), but I ask a question for the One Piece community:
How likely do you think One Piece will address climate change in the future?
So Oda likes to do these things in One Piece that I call "checkboxes." For better or worse, Oda is telling every story he's ever wanted to tell in One Piece. This can range from his comedic musings , how much he likes boobies, to his social commentary on real life issues. However one thing that's noticeably absent from the series is how it tackles climate change.
However, this doesn't mean the hints aren't there. From the very beginning of the crew entering the Grand Line, Nami made it very clear that the weather of the Grand Line was extremely abnormal. As the series goes on, we discover that "abnormal" doesn't sell it too well. I mean, for fuck's sake, there's a hole in the ocean at Eines Lobby for what reason exactly?! And that's just one example of the craziness.
Even in Wano, the entire country is dying due to it's dying ecosystem. Wano is an apocalyptic wasteland.
With the way Oda is pacing things, and how things get more and more higher stakes in the Grand Line, I wouldn't be surprised if climate change as an issue doesn't get brought up until the very end of the series. Maybe it was the ultimate damage the World Government put on the world in some way.
