The Justice League bands together for a meeting, but when they call Aquaman, he’s just a corroded man-fish skeleton in the Aquaman costume who dies. So Batman says the acidic oceans must be getting worse than they thought, so maybe they’d better do something about it. (And then Superman says: “He wasn’t really that big of a help anyway, so it’s not that big of a deal,” at which point he is shushed by the others.) But then, Green Lantern says he’s needed for a space emergency and disappears; Flash takes off without explanation; Batman says he really needs to go fight the Joker, or the Riddler, or someone; Superman says Lex Luthor is probably plotting some dastardly deed, so he’d better go check on that; and Wonder Woman says she’s going to be busy tying someone up with her golden lasso; and so nothing gets done about it.
Then the announcer says: “Holy crap! Our leaders, and even our heroes, aren’t going to do anything about this? Who will save us? Maybe we have to do it: Call your Congressperson today and ask when they’re going to act on climate change!”
