This sounds more like theater than a protest. I especially like the part about the student in the dinosaur costume.

The College Fix reports:

Students chain themselves to tree to protest climate change-induced ‘human extinction’

Students involved in an “Extinction Rebellion” protest at the University of California-San Diego last week chained themselves to a tree in order to alert the public to the hazards of climate change.

The Extinction Rebellion, “most prominent” in the UK according to The Guardian (the UCSD student paper, not the far-left UK publication), is an “international movement that uses non-violent civil disobedience to achieve radical change in order to minimise the risk of human extinction and ecological collapse.”

This UCSD event, dubbed simply “Tree,” also featured student organizer Gio Tamacas in a dinosaur suit laying “next to a pool of fake blood” who “growled at students passing by.”

“The dinosaur […] symbolizes our similar fate if we continue our catastrophic trajectory,” Tamacas said. “Business as usual equals human extinction. The dinosaurs didn’t know what was coming. We knew climate disaster was coming — mass starvation, mass migration, and the sixth mass extinction. We have no excuse if we perish.”

From the story:

[T]hree students tied themselves to a tree in front of the Bookstore during the whole duration of the demonstration, which lasted between 12 p.m. and 1 p.m.

Eleanor Roosevelt College philosophy student Greyson Sims was one of the students chained to the tree. “This is the first among the couple of protests that we want to do to recruit and also to have a presence on campus,” Sims told the Guardian.

One of the group’s goals is to work with the UC Regents to create campus-wide solutions to climate change.
