Clearly the kid is under the mistaken impression that leftists actually want to do something about climate change. They don’t. They just want it as a political issue to: (1) beat their opponents over their heads with, and (2) to build another constituent voting bloc, or cult if you prefer, that will vote for the Dems no matter what.
You see, the left only survives on single-issue voting blocs. Among other groups, this currently includes unions (especially Federal worker unions), blacks, baby killers, environmental wackos, PETA, rich-white-elitists, and the LGBTQ+ crowd. When these groups are no longer reliably Democrat, new ones have to be conjured up.
We have a train burning chemicals everywhere but there’s not been a peep out of Greta or Hollyweird or Harry and MEghan.
