Dozens of State College residents joined students Friday afternoon to take part in the State College Climate Strike. Some skipped their classes or left work to take part in the event to advocate for the cause, joining fellow protesters in more than 150 countries.

These climate change activists began the strike at the Allen Street Gates before congregating on the stairs of Old Main.

Here’s a look a how the strike unfolded Friday afternoon:

Many students brought homemade signs to support climate action and the fight to save the environment.

Put some respect on Mother Earth’s name!

This student turned Penn State’s famous “We Are” chant on its head to advocate for climate reform.

While the university has recently supported sustainability projects such as a massive solar farm in Franklin County, there’s always room for improvement. Perhaps the State College Climate Strike will encourage local leaders to do their part in the near future.
