A core group of about 35 people is marching the entire way, with other supporters joining in for smaller distances. The goal is to inspire action and discussion about climate change.
Chris Ververis is coordinating activities in Colorado. He says the 8-month march helps spread the word and helps citizens feel as though they have a voice.
"Environmental activists and concerned citizens see it as a profound expression of self-sacrifice," says Ververis, "to demonstrate the seriousness of climate change and its consequences."
The march is also passing through other parts of Colorado, including Penrose, Palmer Lake, and Denver. The stop in Colorado Springs includes a rally and a mini-march from America the Beautiful Park to Acacia Park.
