Work with advocacy groups to bring lawsuits against polluters. Name, shame, and boycott polluters; undermine their social license to operate. Work with your state legislature to have the right to a clean environment enshrined in your state constitution, enabling lawsuits against them when they fail.
We’re in it for the long-haul, babes. Focusing on electoral politics every four years isn’t enough. Protests are important but they have to be promises (as @olufemiotaiwo.bsky.social says). If the environment is your thing, get local. Find an existing group and a friendly legislator and pitch in.
To be fair, I feel sorry for everyone losing their jobs, but having Trump's EPA hire new Heritage Foundation "scientists" to make up fake studies would be worse than no studies at all.
