I can't believe I didn't already know this, but apparently, the guys in the band Linkin Park are a bunch of tree huggers.

The rock band started a project in 2004 to support victims of the Indian Ocean tsunami. Today, their work has expanded to address the root causes of erratic and devastating weather events: climate change.

Take two minutes to hear what the band's frontmen have to say.

Mike Shinoda

Wants young people to stay optimistic about our potential to change the world — especially when it comes to our consumer choices.

Chester Bennington

Knows climate change is a huge challenge but believes young people with technology are a powerful force for change.

And after seeing these interviews and seeing what these guys are all about, this song makes a lot more sense.
